Especially today, when urban environments are constantly gaining in importance, the questions of the hour are frequently: how can we draw on contemporary design concepts to create the degree of urban density that is essential for numerous urban qualities and facilities? How can highquality living and efficiency be combined? How to create pleasant urban environments while at the same time using our resources as sparingly as possible? Urban sprawl is easy to bring about; car-friendly settlement types do not require a lot of forethought. Compact cities are a different beast – they are characterised by a constant interplay of innumerable factors; solutions must be optimised and thought through to the last detail. This has always been the great achievement of cities, and this is why they are often so successful. New construction projects – no matter whether they concern urban expansion or restructuring – must attain these qualities as well. This publication is to give as comprehensive as possible an overview of the range of available solutions and elements at the disposal of urban developers. All examples shown have already been built, often following competitions or other procedures, and may be considered models for reflections on urban development. However, the word “model” should not be understood as a perfect example or gold standard to imitate, but rather as a prototype of urbanistic solutions that visualises and illustrates the communication of individual ideas and objectives and serves as a starting-point for the evolution of original ideas. Given this premise, we hope that the present catalogue will provide all actors of urban development – be they experts, interested citizens or political decision-makers – with a tool to facilitate and accelerate planning and fine-tuning processes and bring us all closer to the goal of vibrant new city quarters with high quality of life. 5 PATTERNS OF NEW URBAN DEVELOPMENTS Organisational Framework Role of SK-AT Programme The present publication was compiled in the context of the project CIDEP (City Development Patterns). The entire venture from project idea to printed publication was financially supported by the EU Cross-border Cooperation Programme Slovakia-Austria 2007-2013 (see also www.sk-at.eu). Co-financing enabled the participating partners to address the subject-matter of the project with the necessary depth and scope. CIDEP as part of SK-AT Programme European Territorial Cooperation is one of the European Commission’s objectives for the 20072013 funding period. One instrument towards attaining this goal lies in funding programmes geared at establishing and intensifying cross-border cooperation along the borders of EU Member States. The top strategic goal of the Cross-border Cooperation Programme Slovakia-Austria 2007-2013 is to create a region that due to its dynamic, knowledge-based regional economy, attractive social environment and intact ecological systems can act as a pioneer for Europe. The Slovak-Austrian border region presents excellent prerequisites for becoming one of the bestdeveloped economic spaces in the EU. The two capital cities Bratislava and Vienna are located at only 60 km distance from each other; most company headquarters, universities and research institutions of both countries are concentrated in this area. As a result, the region is ideally suited for evolving into a hub of economy and research in Central Europe. The Cross-border Cooperation Programme Slovakia-Austria 2007-2013 aims at supporting the emergence of a cross-border learning region. Activity field 2.2 “Sustainable Spatial Development and Sound Regional Governance” promotes several measures to which the present CIDEP project wants to contribute. 6 ◣ Support of a joint cross-border spatial planning perspective: the cooperation of experts from the urban planning departments of both Vienna and Bratislava as well as from the field of economy led to the development of a joint understanding of tasks and solutions. ◣ Setting-up of durable structures: the sustainability of the housing development types analysed was a constant element of research. Finding a joint answer to this issue was a key project goal. ◣ Cooperation to foster integrated and sustainable spatial and regional planning policies: by discussing and agreeing on joint values regarding viable housing development types, the findings and experience of the project will influence the administrative practice of the participating partners. Moreover, the contacts established can be reactivated when dealing with further questions at a later date. PATTERNS OF NEW URBAN DEVELOPMENTS Project goal It was the project goal of CIDEP to develop the present catalogue of housing development types potentially suitable for urban expansion ventures in the Vienna/Bratislava region. All types and examples are described in comparable fashion based on uniform indicators and parameters, visualised and illustrated in a clearcut, universally intelligible manner. Project structure/participants The project was initiated and managed by the Vienna City Administration, Municipal Department 18, and the Bratislava City Magistrate. The Viennese architectural studio Franz Kuzmich, the Institute of Urban Design and Landscape Architecture at the Faculty of Architecture and Regional Planning of Vienna University of Technology as well as the Faculty of Architecture of the Slovak University of Technology in Bratislava were commissioned with preparing and developing the content of this publication. In the context of moderated workshops and a study trip, the project team collaborated with a monitoring group composed of experts in order to integrate practical experiences from a wide range of disciplines. 7 PATTERNS OF NEW URBAN DEVELOPMENTS Introduction Importance of housing development types as a subject of analysis Urban growth Many European cities – let alone the Asian or African mega-cities – are expecting a phase of demographic growth. This also goes for Vienna and Bratislava including their environs. A notable population increase has already occurred in recent years and is likely to continue over the next few decades. This is compounded by two other demographic phenomena: the population shares of elderly persons and migrants are both markedly on the rise. Population growth and augmenting prosperity lead to a clear increase in floorspace requirements for housing, education, offices, services, etc. It is therefore an imperative of our time to systematically address the question of how the (presumably needed) hundreds of thousands of new dwellings should look like, as this will decisively influence the look of the inner and outer urban expansion zones of our cities, to specify the tasks they will have to fulfil and to clarify how residents as well as society will be able to afford them. Energy, efficiency and sustainability In addition to the fact that many new spaces must be created for a much higher number of people, the question of necessary restrictions comes again to the fore. Modern solutions must be “smart”, i.e. intelligent in making the most of relatively little. The times when the possibilities fuelled by cheap energy and resources seemed endless and suitably lavish structures could be created are over. Settlement types directly impact mobility patterns, land use, travel distances, self-determination in old age, dealing with the effects of climate change and resource consumption. New buildings and city quarters must be constructed in keeping with the available possibilities while yet creating high utility value. Many believe that cities can indeed be productive, efficient and sustainable and hence contribute significantly to successfully coping with topical and, above all, future challenges. Functioning density From the outset of the project, it was evident that one of the key achievements of urban structural types lies in their high density, and that many advantages of the city (walkable distances, efficient public transport, shops for everyday necessaries, ...) are in fact only made possible by this density. At the same time, high density entails drawbacks that partly nullify these advantages. The search for suitable urban settlement types mostly concerns solutions that enable high development density combined with equally high quality of living. The earlier we identify development types that balance the contradiction between required high density on the one hand and privacy on the other hand, the more easily can citizens be provided with attractive housing that is durably affordable and ecologically sound. Providing an overview of possibilities Any urbanistic plan begins by outlining a programme for its development area. Before decisions regarding land purchases, investments and architecture can be taken, the prime question is: what forms of use are possible in this site, and to what extent? This is where the present “catalogue” comes in to supply information. Already implemented projects highlight the range of available basic structural types and provide a quick overview of what can be done and how potential volumes would appear and look like. Moreover, important characteristics of the model projects are identified as well. In any case, the authors recommend that readers complete this first impression by visiting the development types proposed on-site and using them as “show-houses” to obtain a first-hand understanding of their real-life impact. 8 PATTERNS OF NEW URBAN DEVELOPMENTS This catalogue is to offer a largely complete overview of urban architectural and structural designs ranging from densified single-family units to maximum-density high-rise quarters. All available solutions were to be represented so as to provide a clear picture of potential options: as a kind of thought experiment, readers can try to select one (or several) of these possibilities to choose the “right” settlement type, i.e. the one most appropriate for their specific urban expansion area. This is why actually implemented projects from a comparable cultural setting were compiled for this catalogue. Many of the projects showcased were selected in the context of competitions or other qualification procedures or specially singled out for praise in relevant literature or local practice. Visionary projects that (possibly for good reasons) have not yet moved into the realm of actual implementation were deliberately, albeit reluctantly, excluded. “Patterns serve as a direct bridge to design”, urban planner Kevin Lynch states in his book “Site Planning”. Few urbanistic design tasks are so unique, he contends, as to defy apt description and communication on the basis of examples. Above all analogues and images based on experience allow for a quick run-through of design scenarios, thus triggering an iterative process involving stakeholders. Recurring, similar and hence typical solutions to specific tasks moreover tend to evolve over time and can serve as starting-points for urban design work. Regarding the quality of the projects presented: these examples are no collection of best practices but are to illustrate and concretise possible urbanistic solutions. Of course, many examples are successful, were planned by distinguished architects, chosen in the context of competitions and may be regarded as models. At the same time, however, quality standards are highly dependent on the subjective assessment and preferences of readers/users. This is borne out by the fact that some people prefer to inhabit Gründerzeit houses in condensed urban neighbourhoods, while others favour row houses with small gardens at the periphery. A family van most certainly is no sports car, and vice versa. The diagrams, statistics and texts of this catalogue are to render the characteristics, pros and cons of the different building types transparent. The set of qualities best suited for a concrete site and target group must be identified by the readers of this catalogue. How to use this publication The main body of this catalogue is structured into 12 chapters, each describing one urbanistic archetype. These development types were derived from research into an enormous variety of projects implemented roughly over the past 20 years. Every type is illustrated by several examples shown on one double page each. On the one hand, these examples are to provide a clearcut understanding of the type in question; on the other hand, they are to highlight the diverse application possibilities of this type. The chapter “Definitions and glossary” provides readers with a glossary of the most important terms used in describing the various development types to expound on their meaning and technical relevance. Time-tried and novel methods of research In part at least, the availability of new technical tools enabled the research for this publication to assume a wider scope than comparable earlier works. The present project made use of a great variety of information capturing and evaluation techniques, such as data from geographic information systems, satellite images, aerial images, oblique aerial views, project databases, online and library-based literature research, Google Street View, open-source maps, e-mail and webform communication, etc. Coupled with the involvement of seasoned experts and interdisciplinary study trips, these methods allowed for the implementation of a wide-ranging research project within the available framework. As a result, readers may expect a largely complete catalogue of currently possible development and estate types. The next section will look at the approach employed in greater detail. International search: whatever is possible The present compilation of housing development types and examples is the outcome of an extensive search process. As a first step based on a rough concept of types encountered in comparable cultural settings, the authors looked for suitable, already implemented projects. The construction histories of Vienna and Bratislava over the past two decades were duly analysed. Out of several 9 PATTERNS OF NEW URBAN DEVELOPMENTS hundreds of projects, the authors selected those that represented a certain type effectively or proposed interesting solutions within a given context. Projects outside this geographical area were moreover identified by means of literature research, personal contacts or experiences of the compilers of the catalogue. After collecting and roughly analysing these examples, the material gathered allowed for a review of the originally sketched typology in cooperation with the members of the expert monitoring group. Furthermore, projects representative of every type were selected as examples to give an overview of the full range of possible solutions. It became apparent that in some cases no examples of specific densities combined with specific building types could be identified, while examples were numerous for other types. The selection process was therefore fine-tuned until at least one example per density level could be selected for every type (where possible). In those cases where several possibilities were available, it was tried to highlight the range of possible solutions for one type. It had been a key motive in the selection process to include mainly projects that could be viewed as exemplary and future-oriented. However, this rigid logic had to be abandoned since the experts involved could not agree on what projects to define as exemplary; neither was it possible to identify unreservedly recommendable examples for all situations described in the catalogue. For the sake of completeness and as benchmarks, the publication thus also includes projects that suffer from weaknesses and drawbacks and thus will probably be applied less frequently in the future. Readers can derive the quality attributed to each project from the given parameters, illustrations, descriptive text and, ideally, also from on-site visits. Search for parameters The value of a catalogue lies in the possibility of comparing individual products and selecting a solution for an upcoming planning task. Thus a key first step in compiling the present catalogue lay in the question of what characteristics to draw on to describe settlements. At the outset of the project, a discussion focused on what traits of designs are most significant for the urbanistic scale and tried to operationalise these traits on the basis of indicators. This revealed that the number of themes considered relevant is much larger than those for which suitable measurement methods are actually available or could be established in the course of this project. In practice, reliance on verbal descriptions and expert assessments proved inevitable whenever no viable parameters were available for a given situation. This indicates that many qualities and needs of urban planning have not yet been defined or rendered measurable with sufficient precision and that the assessment of projects or project proposals will in practice be often incomplete. Finally, the present catalogue aims in three ways to enable readers to evaluate the development examples presented: 10 ◣ Graphical representations and photos of standardised situations ◣ Verbal descriptions of projects based on a uniform structure ◣ Urbanistic parameters and typologies where possible and useful PATTERNS OF NEW URBAN DEVELOPMENTS Moreover, all construction projects feature a map and detailed address and can thus be visited to obtain a first-hand, on-site impression. The subjects of this study were to be “urban components”, i.e. areas provided as fully as possible with a range of facilities that in addition to useful internal floorspace include ancillary spaces, such as green and open zones, as well as amenities serving the local community, such as kindergartens, schools and shops for everyday supply. Theoretically, these components are summable at an urbanistic level, which would produce some indication of the capacity and quality of newly built quarters. However, since contemporary urban planning largely discards such homogeneous ensembles in favour of diversity and mixed use, the subject of the present study had to be curtailed to the scope of actually implemented projects (often covering less than one hectare), hence abandoning the idea of measuring the full provision with public open spaces, local shops, etc. on the basis of concrete projects. To work around this problem, one can give a detailed description of the functions provided by the individual development and then aggregate the missing remainder as a fictitious notion. In assessing examples – in particular densities –, this aspect is highly relevant, because some settlement types integrate a comprehensive set of amenities (open areas, circulation areas, communal facilities and rooms, shop and office spaces, etc.), while others only provide residential floorspace but lack other functions or force residents to fulfil these requirements in the neighbourhood. In the verbal descriptions of the individual projects, these factors were identified in greater detail under the headings “Situation within the city”, “Prerequisites of success”, “Quality and flexibility of use” and finally “Quality of urban space”. The next sections expound on the structure of the descriptive texts shown on the left side of every project presentation. For the parameters given on the right side of the project presentations, please consult the following section (“Definitions and Glossary”). Context The following external factors influencing the quality of housing and living in the respective project are described to provide a context for the individual examples: ◾ Situation within the city, traffic/transport links and infrastructure This paragraph provides information about the distance between project and city centre and about the nearest means of public transport/high-level street and moreover lists relevant supply infrastructure in the closer vicinity (e.g. educational facilities, hospitals, shops, etc.). ◾ Location assets This heading describes specific quality-determining characteristics in the direct vicinity (e.g. situation next to a green corridor, adjoining a neighbourhood park, directly connected to an Underground station, …) that have a bearing on the (housing) quality of the individual settlement type. Project description Regarding the development or project area per se, the following aspects were described and visualised: ◾ Prerequisites of success Many qualities of settlements cited as examples cannot be generalised since they depend on specific local or historical aspects. The description of these decisive factors of influence is to enable readers to better gauge the achievements of the respective development or building type. These aspects e.g. include the kind of qualification or planning procedure employed (e.g. competition, developers’ selection procedure, participatory planning process) or special architectural or design challenges that were mastered or should be given particular consideration in connection with this project type. 11 PATTERNS OF NEW URBAN DEVELOPMENTS ◾ Quality and flexibility of use of individual structures This paragraph deals with such aspects as: ◾ ⚫ Suitability of rooms for daily use (quiet, daylight incidence, quality of layouts, natural ventilation, north-facing flats) ⚫ Fostering of a sense of neighbourship (number of dwellings per building/staircase/entrance, rooms for communication and joint activities, access solutions) ⚫ Possibility of integrating non-residential functions (number of storeys, possibility of creating offices or shops, wing depth/useful floorspace, attractive entrance/lobby zones for enterprises, accessibility by car, frequency and visibility, handling of noise/exhaust fumes, etc.) ⚫ Are safety needs of users met (anxiety-inducing spaces, social control of circulation routes, attractiveness of public spaces and entrance zones)? ⚫ Can shopping facilities within walking distance be created or are already in place? Experience shows that a supermarket needs the purchasing power of at least 3,000 local residents to flourish; a range of shops for extended supply (supermarket, drugstore chain outlet, tobacconist’s, bank, florist, cafés and restaurants) only makes economic sense starting at 5,000 residents. Availability and quality of open spaces This heading describes and assesses open spaces (from public to private) and their quality of use within the settlement type analysed, e.g. private gardens, areas for play, sports and communal activities as well as circulatrion routes inside the development. ◾ ⚫ What spatial qualities are generated by the individual project type? Can private, communal or public use be implemented with a good quality standard, given the project’s density and building type? ⚫ Do flats feature sufficient private open spaces? What open spaces encourage communal use? ⚫ How well are the twofold functions of open spaces - circulation vs. rest and communication - balanced? ⚫ Were open spaces designated for young people? What role is assigned to stationary traffic (parked vehicles) in the open spaces? Neighbourship, communal facilities This heading assesses the potential of the respective development type to promote a sense of neighbourship and community, e.g. by means of shared open spaces, communal rooms in buildings, arrangement of flats into moderatelysized groups or number of flats accessed via one staircase. ◾ Quality of urban space This paragraph addresses the impact of the project on the cityscape, streetscape and environs and explores to what degree the design chosen allows responding to these needs. In this context, the following aspects were assessed: ⚫ 12 Suitability for pedestrians (short distances, prospects, vistas and spots of interest for pedestrians, such as shops/cafés, etc., avoidance of areas experienced as uninteresting or unsafe, such as isolated base zones, garages/gates, parking lots, undefined spaces) PATTERNS OF NEW URBAN DEVELOPMENTS ⚫ Variety, small dimensions and human scale of buildings, mainly for the base zone (number of separate buildings and/or uses per front length, possibility of active ground-floor utilisation, possibility of also creating small units to enhance variety, design of transition zones between public space and buildings, façade structuring of large volumes) ⚫ Public space orientation of buildings by means of shop displays, windows, balconies, transparent building elements, illumination, design of transitions from private to public areas ⚫ Avoidance of shading and visual dominance of streetscape, unobstructed view of scenic spots, landmarks and points of reference Need for further research input The very intensive work for the CIDEP project has shown that despite massive commitment and a broad approach many themes identified at the project outset could by far not be dealt with exhaustively. Some reasons for this include the following: ◣ Recent urban development tends to eschew large-scale, homogeneously developed areas; multifaceted solutions and small lots dominate. The hypothesis that phenomena and parameters can be empirically observed on the basis of ideal-typical projects had to be largely curtailed. Such an approach would call for the construction of fictitious development zones. ◣ Many important parameters cannot be measured reliably on a reasonable time and cost basis and thus had to be eliminated or replaced by expert assessments or verbal descriptions. Therefore many questions, such as energy efficiency, resident satisfaction, construction costs or mobility behaviour of different settlement types, seem highly relevant for decision-making but cannot be operationalised. The relevant available literature likewise proved insufficient or inapplicable. ◣ Finally, the often required qualitative assessment proves a difficult or sensitive issue. While the project management team united a diversified group of planning and construction experts, the positions of other user groups were by necessity neglected. The widespread – certainly appropriate – reticence to criticise recent projects equally impedes the evaluation of design solutions. The experience made in compiling the present publication shows that many questions and aspects must remain unanswered or unconsidered for the time being; hence further studies would be highly welcome. 13 PATTERNS OF NEW URBAN DEVELOPMENTS Definition and Glossary Term Explanation A Aboveground parking (sq m) Surface exclusively used as parking lot at ground-floor level and mostly reserved for owners/tenants or customers of a development. Access type Defines the arrangement of corridors and staircases inside a building. The projects presented distinguish between the following types of flat access: Landing access: 2 or more flats are situated on one landing. Central access: 4 or more flats are situated around a staircase. Central corridor access: flats are situated on both sides of an access corridor. Covered walkway/arcade access: flats are accessed from an external walkway. Direct access: flats are accessed directly from the street. Amenities for residents and locals Private facilities and amenities for the population of a residential area, e.g. retail shops, cafés, restaurants, personal services, doctor’s surgeries, etc. Areas for third-party use Sum total of all useful (non-residential) floorspace for rent of a given project. Atrium house An atrium house receives daylight via a central space that is either an open-air internal courtyard or designed as a glass roof. Thus the building may also forgo outside-facing windows. Average flat size (sq m) Average useful flat surface of the individual project. B Base zone Ground-floor zone. This is the part of a building in closest visual and functional contact with the adjoining streetscape and usually extends over one (sometimes more than one) storey. This zone frequently offers the possibility of accommodating spaces for commercial use, e.g. shops, cafés, small offices or studios. The design of base zones is of prime importance for the atmospheric quality of the adjoining streetscape. Basic supply Cf. shops for everyday necessaries Blind wall Cf. fire wall Block grid Usually rectangular grid-type arrangement of > urban blocks in a city quarter. Brownfield site Area within city limits formerly used for industrial or commercial purposes and subsequently cleared for new forms of use due to closedown or relocation. Building line This publication defines the building line as the boundary between public circulation areas (footpaths, lanes, streets and squares) and private development surfaces. Built-up surface (hectares) The built-up surface results from the maximum area covered by a horizontal projection of all aboveground storeys. C Central corridor access Access type that allows for the individual flats of one floor to be accessed via a central corridor running parallel to the building’s longitudinal axis. This type is characterised by very low consumption of space for landings and stairs and allows very deep wings (up to 20 m) and hence high densities. A drawback lies in the fact that many dwellings often face only in one direction, which can entail problematic flat layouts and orientation. Circulation area (sq m) Public or semi-public open space of a plot exclusively used for traffic. Concierge service Service rendered in the management of multi-storey residential buildings. In addi tion to supervision and care services on behalf of residents, staff also renders a variety of personal services, such as transporting items, accepting parcels, runnings mall errands or taking care of pets during the owner’s absence. Covered walkway/ arcade Horizontal walkway along a building façade serving as access for upper-storey units. Walkways are vertically linked by staircases. Generously dimensioned walkways can also serve as communication areas. The advantage of this system lies in 14 PATTERNS OF NEW URBAN DEVELOPMENTS the fact that a number of flats arranged side by side can be reached via one staircase, which is not possible with just one landing; at the same time, the drawbacks of a central corridor are avoided. Cross-ventilation Flats with windows on two opposite sides allow for cross-ventilation, an important quality criterion to safeguard efficient air change e.g. on hot days. Some access types (e.g. central corridor) preclude this possibility. Cul-de-sac A cul-de-sac (dead end) is a street or path with only one inlet/outlet. Its purpose is traffic-calming and keeping residential areas free of through-traffic. D Developers’ competition Selection procedure for developers applied in Vienna, in whose context the City Administration or wohnfonds wien (Fund for Housing Construction and Urban Renewal) as land owners sell lots for social housing projects and grant subsidies in a competition procedure (focusing on quality, costs). Docklands Originally, the term “docklands” referred to part of the Port of London. With the decline of the shipping industry, the abandoned sites were redeveloped into flats and offices. Projects in similar locations and with similar characteristics are often likewise called docklands. Double-line arrangement Cf. central corridor access Dwelling (housing unit) Self-contained series of rooms normally connected and destined for residential purposes; permits conducting a private household. E Elementary school, compulsory School for children aged 6 to 10 Extended supply Cf. shops for everyday necessaries F Façade distance Average distance between the volumes of a project or surrounding buildings of relevance for users of the dwellings. This is significant because wider spaces between volumes tend to ensure greater privacy, better daylight incidence and views as well as less noise from neighbours. Due to the value distribution observed, the following classes were established: small = distance less than 12 m medium = distance between 12 and 25 m big = distance in excess of 25 m Fire wall A fire wall (fire partition, fire barrier) is a wall that divides a building into separate fire compartments and is to prevent a fire from spreading to other buildings or building sections. In most cases, fire walls built along a building’s boundary must present no apertures and therefore are also referred to as “blind” or “blank” walls. Flat sizes (sq m) Refers to the range of useful flat surfaces (excluding open spaces). Flats extending across entire building depth Flats with windows facing two opposite sides of a building. This design allows for cross-ventilation and daylight incidence from both sides. It moreover offers the advantage of having the flat face two directions, which permits functional optimisation (views, quiet, balconies, etc.). Flats/hectare of reference surface Refers to the intensity of use of a development type. The more flats can be accommodated on one hectare of building land, the more economical in land use and compact it will turn out. However, in comparing this parameter among projects, the size of the flats and the share of surfaces destined for housing in the overall useful floorspace must be considered as well. The number of flats can also be placed in relation to the size of the plot of the project (flats/hectare of plot suface). Flats with private open spaces (%) Proportion of flats within the overall project that offer annexed open spaces in the form of tenant/resident gardens, loggias, verandas, balconies or terraces. Floor area ratio (German acronym GFD) Ratio of how many storeys would have been built on a given plot if all floorspace were evenly distributed across the entire plot. To ensure comparability with earlier studies and meaningfulness within the overall urban-structural context, the present publication makes use of the entire reference surface (= gross development sur- 15 PATTERNS OF NEW URBAN DEVELOPMENTS face). Since the standard reference value commonly used is the net plot surface, this variable is determined as well. Gross floor area ratio (gross GFD) = gross floorspace/reference surface Net floor area ratio (net GFD) = gross floorspace/net plot surface G Garden wing Volume shielded from the street by other volumes and hence not directly accessed via a street. Green belt Continuous system of green and open spaces encircling a settlement area or city in the style of a belt. Normally, green belts are specially protected and legally safeguarded by means of corresponding land use plans. Gross floorspace (sq m) The gross floorspace (German acronym BGF) is the total floorspace of all aboveground storeys. It is calculated on the basis of the overall dimensions of buildings and hence includes walls and internal circulation routes. There are three BGF categories; their ratio is given in percent: Housing: flats with proportional share of annexed facilities and circulation/access areas Work: enterprises including studios, surgeries, etc. with proportional share of facilities and circulation/access areas Services: social infrastructure facilities, such as kindergartens, schools, social service offices, etc. H Head volume Independent volume at the end of a row or attached development if its layouts differ from that of the row and if it features a separate access system. Heat requirement The heat requirement (German acronym HWB) is the calculated amount of energy to be input into a building during the heating period to maintain the desired room temperature. Housing tenure Flats may be rented or owner-occupied. I Inner urban expansion Measures taken to mobilise/create development potentials in built-up, condensed urban zones, mostly as a result of the conversion of former industrial sites, barracks, railway stations, etc. Smaller lots, gaps between buildings and poorly used areas are also drawn upon for inner-city densification. J K Karree (court, rectangle) Closed, rectangular or trapezoidal arrangement of buildings enclosing a shared (often greened) courtyard. L Landing access Building type for multi-storey volumes where one to three flats (though there may be more) are accessed from the staircase of one storey. Line of sight Zone kept clear of buildings of any kind to allow for vistas and daylight incidence. Live/work units Dwellings conceived to allow for a combination of living and working in one place. The work function is often located at ground-floor level while the residential unit can be found directly above. These units are to take account of the space requirements of micro enterprises while improving the mixed-use situation and variety in a quarter. Lot coverage ratio The lot coverage ratio is the portion of the net plot surface covered with buildings (percent). Lot coverage ratio (%) = built-up area/plot surface x 100. Allows for assessing the degree to which a property was built up. Low-energy house, low-energy New and rehabilitated older buildings that attain legally defined energy engineering house standard requirements and energy standards. M Maisonette 16 A maisonette (split-level flat) extends over more levels than one, connected by an PATTERNS OF NEW URBAN DEVELOPMENTS internal flight of stairs. This design can be used to create flats facing in two directions despite central corridor access and also allows for providing more units with direct building access and a garden or roof terrace. Mean number of storeys Mean number of storeys = gross floorspace/built-up surface. Mixed timber-solid masonry construction Construction method that applies two construction techniques jointly in one building. Solid masonry is used e.g. for the underground garage and ground-floor level, while timber construction is employed for all other storeys. N Net plot surface (hectares) The net plot (or development) surface is equal to the areas designated for construction purposes, the open areas forming part of the property and the internal access and circulation routes. It results from the > reference surface after subtracting circulation areas, open and distance spaces as well as the half road widths added to the reference surface. Number of dwellings Sum total of all flats (dwellings) of a given housing project. Number of slots Number of all car parking slots available aboveground or belowground to residents and enterprises of a project/object. Number of storeys Number of aboveground storeys. In case of buildings of uneven height, the lowest and highest number of storeys is given. Fully developed rooftop storeys are assigned the letter “D” (for German “Dach” = roof), while recessed top storeys (terrace storeys) are assigned a “T”. Individual objects differing from this categorisation and forming part of a larger, uniformly structured development were disregarded (e.g. one-storey daycare centres, additions, etc.). O Open space (sq m) This category states open areas within a property or plot (public streets and parking lots outside the property or plot surface are excluded). Open spaces may be green spaces, footpaths, cycling tracks and other paved surfaces. According to accessibility, they are classified as: Public: everybody may enter and use these spaces. Partially public (semi-public): these spaces are entirely or primarily reserved for the residents of a development. Private: rented or owner-occupied open spaces, e.g. tenant or owner-occupied gardens, open spaces of kindergartens or children’s groups. Children’s playgrounds open to all residents of a housing development are specially marked as such. P Passive house, passive house standard Building whose room temperatures are attained by means of adequate heat insulation and largely “passive” resources, such as sunlight incidence, heat emitted by persons and waste heat of technical appliances. Patio Interior courtyard of a townhouse. Perforation In case of very long buildings, this is a transverse interruption in the volume (not ches extending over several storeys), usually a structure-creating device. Perimeter development Cf. urban block Permeability, permeable The permeability of a development refers to the possibilities it affords pedestrians and cyclists to cross the property as well as to the cross-vistas generated. Since pedestrians are highly sensitive to distances, the permeability of developments is an important contribution towards pedestrian-friendliness. Protection zone “Wald- und Wiesengürtel” The “Forest and Meadow Belt” of Vienna was stipulated under law to preserve and create green zones in order to protect the health of the urban population and ensure opportunities for open-air recreation. These areas may be used for agriculture or forestry. Public space Urban space that is freely accessible for everybody and built, managed and maintained by the municipal authorities. In addition to public traffic areas for pedestrians, cyclists and motorised vehicles, this category also includes parks and squares. 17 PATTERNS OF NEW URBAN DEVELOPMENTS Q Quarter, city quarter City quarters (residential quarters) are defined as moderately sized social reference systems often composed of only a few streets and felt to be a “homogeneous” part of the city that is delimited from other city quarters both spatially/geographically and on the basis of the social or ethnic composition of its population (no official boundaries). R Reference surface The reference surface (= gross development surface) is the total surface of the investigated area to which the parameters given refer. In case of larger projects, it also comprises internal access zones, public open spaces, distance spaces and half of the adjoining street width (where required to provide access to the project). Residential street Cf. traffic-calming Row Multi-storey building type whose layout is composed of rectangular attached units, resulting in an oblong shape. S Semi-public space This publication uses the term to denote open spaces that are part of housing projects and primarily designated for use by residents of the project in question. Service infrastructure costs Service infrastructure costs are construction and maintenance costs of road and utility networks (electricity, gas, water, sewers, ...). Usually, these are largely borne by the public authorities. Keeping these costs per dwelling as low as possible is a key objective of economically sustainable development. Service infrastructure costs per dwelling The present publication defines this term as the costs arising per dwelling for the construction of the local access street including supply utilities. The costs were estimated on the basis of the road type required (width, appointments), the necessary circulation route length and standard costs per running metre of supply lines. Finally, the projects were divided into three categories (< €/D 3,000: low; €/D 3,000-10,000: medium; €/D > 10,000: high). Shading Keeping sunlight incidence from buildings or open spaces. This may have positive effects by avoiding unwanted effects like dazzle, reflections, overheating of buildings, or negative ones, e.g. excessive shading of open spaces or neighbouring buildings. Shops for everyday necessaries Supply of everyday necessaries, mainly foodstuffs but also personal services; centrally located and within walking distance. Accessibility within walking distance is defined as approx. 400-800 m at most (12-15 minutes). Experience shows that a supermarket needs the purchasing power of at least 3,000 local residents to flourish; a range of shops for extended supply (drugstore chain outlet, tobacconist’s, bank, florist, cafés and restaurants) only makes economic sense starting at 5,000 residents. Single-flat landing Cf. landing access Social infrastructure Portmanteau term for a variety of municipal facilities, such as educational establshments (schools, daycare centres, …), services (assistance, craftspeople, …), healthcare (physicians, pharmacies, hospitals, ...), cultural and religious institutions (libraries, event venues, …). Solid timber construction Timber construction technique that makes overall use of solid elements for walls, roof and ceiling. Standalone volume A standalone building is not attached to any other volumes. Stiege (staircase) Specifically Austrian term that defines all flats accessed via one staircase; also part of a complete address in housing developments with several wings (and hence, staircases). Street courtyard Courtyard extending along an access road. T Temporary utilisation Temporary utilisation of a building, area or plot. Traffic calming Streets or zones where motorised individual traffic is strongly regulated or decelerated to favour pedestrian traffic. Includes residential streets, pedestrian zones and 30 km/h zones. Two-flat landing Cf. landing access Types of parking space One can distinguish between slots outside a building (open-air), in underground 18 PATTERNS OF NEW URBAN DEVELOPMENTS garages (UG) and multi-storey car parks (German acronym HG). U Urban block Urban blocks (city blocks, apartment blocks) are typical inner-city structures composed of multi-storey, continuous, closed volumes (cf. perimeter development). Urban wilderness Green zone, usually of smaller dimensions or part of a larger green area and without visible measures taken to cultivate/care for its vegetation (spontaneous/overgrown vegetation). Urbanistic master plan Integrated overall plan embodying an urbanistic vision to provide qualitative and quantitative pointers for the urban development of larger or multiple areas. It lays down a roadmap for further planning and implementation steps and targets authorities, owners, future users, investors as well as all actors affected by the planning and implementation process. Useful living area (sq m) Sum total of all flat surfaces of the project in question. Open spaces like balconies, terraces, etc. were not included; neither were general circulation and access zones, such as staircases, corridors and communal areas inside a building (e.g. storerooms for prams and bikes, waste container rooms, building utility rooms). V W Walking distance Distance covered by pedestrians. This distance is not always the same and increases with the attractiveness of the destination (big park, underground station, major public facility). Approx. 300 m can be covered in 5 minutes; approx. 800 m, in 15 minutes. Only a small part of the population is willing to walk more than 500 m for everyday chores; thus short and attractive walking distances are of the utmost importance for creating a pedestrian-friendly environment. Wing depth (m) Depth of a volume between the two façade surfaces on each side. Wing depth strongly influences development intensity as well as built floorspace quality. Thus useful floorspace increases markedly with wing depth; at the same time, however, this means that the number of windowless and hence badly lit rooms augments as well. X Y Z Zoning Distribution of functions and (partly) design types in space; defined by an urban development plan. 19 PATTERNS OF NEW URBAN DEVELOPMENTS 20 PATTERNS OF NEW URBAN DEVELOPMENTS Overview of Types and Examples 21 PATTERNS OF NEW URBAN DEVELOPMENTS Overview of Types and Examples GFD up to 1.0 1 1.0-2.0 2.0-2.5 Tamarisken- Traviata- Borneo2 gasse gasse over 3.5 Kabelwerk Borneo1 Nove Rusovce 2a 2b 3a 3b 2.5-3.5 Drotarska ul.

This type allows for the construction of floorspace densities of up to 1.5 with 1- to 2-storey developments. In case of multi-storey buildings (example from Amsterdam), densities of up to 2.3 are possible. Visually condensed impact due to private gardens shut off from the surroundings. Since every flat has its own private open space that is invisible from outside, there is little need for additional, public open spaces. Thus outdoor spaces are not designed for communication or leisure activities but mostly serve as access zones. Due to the internal circulation network, the houses are easy to access on foot or by bike. Access by car is possible but limited. Although very popular in Austria, this building typology is only viable for implementation in the urban periphery (due to high land prices). Access type: Preferred orientation: Ground-floor level suitable for non-residential use: Suitability for flat variety: Suitability for priv. open spaces: Privacy (invisible f. outside): direct access from outside individual houses face south no low high high Lot size (individual houses): Lot width: 200-300 sq m > 12 m Public open spaces: Open space quality: none low Parking spaces: multi-car parking lot or garage 23 PATTERNS OF NEW URBAN DEVELOPMENTS 01/ Wohnanlage Tamariskengasse (1220 Wien, Tamariskengasse 102) In brief Multi-element housing project with 231 flats in one-storey atrium buildings, two-storey terraced houses and three-storey residential blocks that shield the development along its northern and western edges. The private atmosphere of the open areas is strongly emphasised by walls. The open spaces enclosed by the built volumes are public, carfree and highly differentiated in design. Situation within the city The complex is situated in the north-eastern urban expansion zone of Vienna (22nd municipal district). An Underground station is situated in front of the development, while tram and bus stops are located at a distance of 100-400 m. Cars access the complex via two culs-de-sac at its western periphery (no through traffic). A school, kindergarten and shops for daily necessaries can be found nearby. Location assets Easily reached by public transport due to extension of Vienna Underground line. Prerequisites of success The residential complex Tamariskengasse is an example of how excellent housing quality can be attained with highly condensed low-rise buildings. Cars may only be parked in an underground garage; the adjoining section of Tamariskengasse between the garage entrances is likewise car-free (part of Tamariskengasse is a residential street). However, the narrow lanes permit only limited use. Quality and flexibility of use of individual structures This estate type exclusively serves housing purposes. Most flats face south. Threestorey structures along the western and northern periphery shield the complex against noise and wind from outside. The interior zone is tranquil and surrounded by buildings staggered in height. Flexibility of use was not aimed for. Availability and quality of open spaces Two large squares linked by a common form the spatial centre of the housing development Tamariskengasse. All flats have their own private open spaces designed as southfacing, secluded terraces, loggias and, in case of atrium or terraced houses, walled garden courtyards. Freed of the constraints of traffic logistics and road layouts, public space emerges as a differentiated tissue of narrow lanes, ample squares and green zones boasting trees and water basins. Young people find room to move both in these open spaces and in the residential street (Tamariskengasse). Neighbourship, communal facilities The differentiated range of open spaces fosters a sense of neighbourship. The range of communal facilities is limited to those stipulated under building law (rooms for parking prams and bikes, general-purpose storage room). Quality of urban space The entire complex is car-free and generates open spaces that are interesting for pedestrians. Since this project is a purely residential one, its appeal for non-inhabitants is limited. 24 PATTERNS OF NEW URBAN DEVELOPMENTS 01/ Wohnanlage Tamariskengasse (1220 Wien, Tamariskengasse 102) Reference surface, hectares Net plot surface, hectares 3.87 3.57 Built-up surface, hectares Lot coverage ratio, % 1.50 42 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % Floor area ratio, gross Floor area ratio, net Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % Circulation areas, sq m Aboveground parking, sq m Number of slots Type of parking Service infrastructure costs/dwelling Year of completion Planner Developer 6-12 direct, SP, LG narrow 1-3 1.7 26,000 100 0 0 0.67 0.73 19,000 231 60-120 82 65 60 229 73 14 13 0 20,700 0 11,150 9,300 250 336 0 231 TG low 1993 Rainer GESIBA 25 PATTERNS OF NEW URBAN DEVELOPMENTS 02/ Wohnhausanlage Traviatagasse (1230 Wien, Traviatagasse 21-29 / Pfarrgasse 67-73) In brief The housing development Traviatagasse is a purely residential complex with some buildings designed to create a sense of community. The settlement is composed of oneto four-storey single-family and terraced houses with highly urban character, high density and staggered heights that decrease towards the centre of the project. Two rows of buildings to the west and north shield the other volumes, thereby generating a spatially closed ensemble slightly reminiscent of a fort or castle. Three rows of four-storey terraced houses are situated to the east; open to the south, the project interior accommodates a diagonally rotated square block of three-and-a-half-storey courtyard houses (“castrum”). Situation within the city The settlement is part of a residential area at the southern periphery of Vienna and adjoins an industrial zone in the village of Inzersdorf. Bus stops are situated adjacent to the project, which is also connected to the road network on three sides. The distance from the village core of Inzersdorf with all its facilities (social infrastructure, shops) is approx. 600 m. Location assets To the east, the project is bordered by a protected green zone (green belt “Wald und Wiesengürtel”). Prerequisites of success On the basis of an urbanistic master project, four construction stages providing different solutions to the task of devising urban, condensed low-rise housing were implemented. As a whole, the residential complex – in particular the “castrum” at its centre – presents an extremely introverted character, indicating that maximum privacy was a key design goal. Quality and flexibility of use of individual structures The 169 flats differ in type but mainly face the block interior. The different types include one-storey atrium buildings, staggered two-storey maisonettes, four-storey terraced houses, arcade-style volumes and three- to four-storey courtyard houses offering multiple-use spaces on the ground floor, first-floor bedrooms and a residential storey with access to a roof terrace above. Flexibility of use was not intended. Availability and quality of open spaces The open spaces allocated to the individual flats are mostly paved garden or roof terraces. Most publicly accessible open spaces, too, are paved; the share of green spaces is overall low. The rhomboid contours of the open spaces do not favour communal use; the open spaces are unsuitable as a meeting point or play area for young people (surface problem). Neighbourship, communal facilities A sense of neighbourship is generated and fostered by the secluded open spaces inside the complex and the communal facilities, since the development accommodates e.g. a children’s house, a youth house and a sauna building. Quality of urban space This generously dimensioned residential development is reserved for pedestrians only but projects a closed and introverted visual impression. 26 PATTERNS OF NEW URBAN DEVELOPMENTS 02/ Wohnhausanlage Traviatagasse (1230 Wien, Traviatagasse 21-29 / Pfarrgasse 67-73) Reference surface, hectares Net plot surface, hectares 4.10 3.50 Built-up surface, hectares Lot coverage ratio, % 1.24 35 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 10/18 RH narrow 1-4 2.9 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 36.300 97 0 3 Floor area ratio, gross Floor area ratio, net Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface 0,89 1,04 20,400 169 121 47 40 Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % 169 55 0 45 Housing tenure Non residential use, sq m 600 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 22,600 0 72 28 0 Circulation areas, sq m Aboveground parking, sq m Number of slots Type of parking Service infrastructure costs/dwelling 130 0 TG medium Year of completion Planners Developer 1991 Abraham,Pruscha,Buck,Giencke Lautner, Scheifinger, Szedenik GSG 27 PATTERNS OF NEW URBAN DEVELOPMENTS 03/ Siedlung am Park / Kabelwerk, Bauplatz C (1120 Wien, Thorvaldsengasse 36-44) In brief The project Siedlung am Park is part of the new residential quarter Kabelwerk in a southern part of Vienna. The multi-coloured single-family dwellings with up to three storeys are densely packed. To yet ensure privacy, the angled structures are introverted, face south and boast small gardens or terraces. Situation within the city This former industrial site – hence the name ”Cable Works” – is situated in a densely built-up southern part of Vienna (12th municipal district) and connected to the road network by public streets encircling the entire complex, while the Vienna Underground is only 100 m away. The project includes a range of supply options for everyday necessaries and social infrastructure: the ground-floor zones of the quarter offers space for shops, offices, communal facilities, children’s playrooms, cafés and restaurants. A children’s daycare centre is likewise part of the development. Location assets Part of the large-scale project Kabelwerk with direct connection to the Underground network. A new park adjoins the project to the east. Prerequisites of success An urbanistic competition allowed future residents to codetermine the final outlook. This settlement type must not be viewed on its own but in context with the entire Kabelwerk project and its infrastructure. Quality and flexibility of use of individual structures “Siedlung am Park” offers many different types of dwellings: atrium buildings, single units stacked atop multi-flat structures, maisonettes, traditional one-level apartments. There are a total of 67 units, all of which face the private gardens to the south. This results in high living quality and individuality of the complex despite massive densification, yet precludes contact with public space. For its inhabitants, Siedlung am Park is an alternative to run-of-the-mill single-family homes. The project did not strive for flexibility of use. Availability and quality of open spaces Circulation is safeguarded by footpaths leading directly to the private gardens. Except for these gardens, the project does not offer space for young people to spend time in; however, such areas exist in the public zones of the Kabelwerk quarter as whole. The buildings are directly accessed from an underground garage. Neighbourship, communal facilities A sense of neighbourship is created by the single-family home character and the circulation routes inside the project. There are no communal facilities. Quality of urban space Siedlung am Park delimits the Kabelwerk quarter in its entirety vis-à-vis the older singlefamily homes to the south and the new park to the east. The structure of the open spaces renders the overall project permeable for non-residents as well. 28 PATTERNS OF NEW URBAN DEVELOPMENTS 03/ Siedlung am Park / Kabelwerk, Bauplatz C (1120 Wien, Thorvaldsengasse 36-44) Reference surface, hectares Net plot surface, hectares 0.37 0.26 Built-up surface, hectares Lot coverage ratio, % 0.17 64 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % Floor area ratio, gross Floor area ratio, net Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface 4-7 direct narrow 2-3 2.2 3,674 100 0 0 0.99 1.41 3,123 26 101-130 120 100 70 Flats with open space 26 Of which with private garden, % 100 Of which with balcony, loggia, % 0 Of which with terrace, % 85 (many flats with own gardens and terraces) Housing tenure Non residential use, sq m Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % Circulation areas, sq m Aboveground parking, sq m Number of slots Type of parking Service infrastructure costs/dwelling Year of completion Planners Developer owner-occupied 0 950 56 0 44 0 0 0 26 TG medium 2006 Schwalm-Theiss, Gressenbauer, Bresich Kabelwerk Bauträger GmbH 29 PATTERNS OF NEW URBAN DEVELOPMENTS 04/ Borneo Eiland 1 (Amsterdam, Feike de Boerlaan) In brief Borneo Eiland 1 is a quarter in the former docklands that reinterprets the traditional Dutch urban row-house. While the plots are small, shared courtyards meet the social objective of providing affordable housing for families with children close to the city centre, despite the high degree of densification. Situation within the city The project is situated at 4 km from the city centre. The surrounding quarter is composed of 1,950 townhouses and three blocks with 150, 204 and 214 apartments, respectively, as well as 5,000 sq m for commercial uses partly integrated into the blocks. The distance to the nearest bus stop is 300 m; to the tram, 600 m; and to shops in the vicinity, likewise approx. 600 m. The quarter is surrounded by residential streets. Densification allows for the proximity of shops and infrastructure within walking distance. Green areas and playgrounds are also situated close by. The project boasts shared courtyards and an elementary school at only 600 m. Location assets By the water’s edge, uncluttered views, residential streets with playgrounds. Prerequisites of success Urbanistic design embracing the two peninsulas Borneo and Sporenburg and stipulating the same rules for all architects working on the different lots. The 30% social housing share required under law was created elsewhere in this quarter. Quality and flexibility of use of individual structures The project is exclusively composed of maisonettes, with the flats facing either north/south or one side only. A garage for residents is located below the courtyard. The higher ground-floor premises provide flexibility of use. Availability and quality of open spaces The residential streets lead into spacious courtyards, from which several houses are accessed. The courtyards allow for group activities but also accommodate separate, individual “front gardens”. Each dwelling has a roof terrace or patio. Neighbourship, communal facilities A sense of neighbourship is engendered by the shared courtyards, especially for persons in the creative industries, due to courtyard studios. Quality of urban space Borneo Eiland 1 represents an introverted design but also offers street-side, groundfloor flats with direct access to the sidewalk and street as a gesture towards a more vibrant and lively urban space. 30 PATTERNS OF NEW URBAN DEVELOPMENTS 04/ Borneo Eiland 1 (Amsterdam, Feike de Boerlaan) Reference surface, hectares Net plot surface, hectares 0.56 0.35 Built-up surface, hectares Lot coverage ratio, % 0.25 71 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 8/12/14 narrow 2-3 2.4 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 6,100 100 0 0 Floor area ratio, gross Floor area ratio, net 1.09 1.74 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m 73 191 120 67 9 0 91 0 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % Circulation areas, sq m Aboveground parking, sq m Number of slots Type of parking Service infrastructure costs/dwelling Year of completion Planner Developers 4,880 67 2,020 0 35 65 0 0 0 36 TG medium 2000 Marlies Rohmer New Deal Amsterdam NL 31 PATTERNS OF NEW URBAN DEVELOPMENTS 05/ Borneo Island 2 (Amsterdam, Borneokade) In brief Borneo Eiland 2 reinterprets the traditional Dutch urban row-house, presenting two variations of the basic row-house type and five variations of the basic one-level apartment type. The location quality in the former docklands with an uncluttered view of the water is high, and despite massive densification and a small lot, it was possible to create largely individual housing options. Situation within the city The quarter is situated 4 km from the city centre near Sporenburg and Borneo on cleared areas formerly occupied by docks. The entire quarter is composed of 1,950 townhouses, three blocks with 150/204/214 apartments and 5,000 sq m of commercially used properties partly integrated into the blocks. Bus stops can be found at 300 m and a tram stop, at approx. 550 m. There are no shops inside the quarter; the distances from the social infrastructure facilities in the blocks, the elementary school or facilities in the adjoining quarters in the western part of the peninsula are relatively long (approx. 1 km). Location assets By the water’s edge, uncluttered views, residential streets with playgrounds. Prerequisites of success Urbanistic design embracing the two peninsulas Borneo and Sporenburg and stipulating the same rules for all architects on different lots. Quality and flexibility of use of individual structures Corresponding to the situation of the pier, the flats mainly present a southern/northern orientation. The introverted design allows for privacy despite high densification. No mixed-use approach was implemented to preserve the character of a tranquil residential area. However, flexibility of use is safeguarded: the ground-floor rooms have a ceiling height of 3.5 m, which allows for potential conversion of these spaces into service facilities or studios. The original concept of allowing for multiple use of the individual ground-floor garages to create a more vibrant and lively streetscape was taken up only in a few cases. Availability and quality of open spaces Access from the residential streets leads via the garage to a patio and on to the house entrances. There are no semi-public spaces in the quarter and no front gardens; the buildings directly adjoin the residential street. Thus there are no specially designated areas for young people to spend time in. Instead of a shared underground garage, the car slots were integrated into the buildings, i.e. cars can be parked at ground-floor level within the row-house lot. Neighbourship, communal facilities Neighbourhood appeal is generated to a limited degree; along the northern edge, every five flats share one common access zone at ground-floor level. All flat entrances are on the ground-floor. There are no communal facilities. Quality of urban space The residential streets with ground-floor shared entrances create an attractive streetscape for the quarter. 32 PATTERNS OF NEW URBAN DEVELOPMENTS 05/ Borneo Island 2 (Amsterdam, Borneokade) Reference surface, hectares Net plot surface, hectares 0.97 0.64 Built-up surface, hectares Lot coverage ratio, % 0.49 77 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 8.4 resp. 40 narrow 2-4 2.7 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 13,400 100 0 0 Floor area ratio, gross Floor area ratio, net 1.38 2.09 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m 10,720 126 60-100 85 197 130 126 0 14 86 owner-occupied/rented 0 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 3,220 0 22 78 0 Circulation areas, sq m 280 Aboveground parking, sq m 260 partly integrated into building (ground-floor) Number of slots 36 Type of parking aboveground Service infrastructure costs/dwelling medium Year of completion Planner Developer 2000 Rudy Uytenhaak New Deal Amsterdam NL 33 PATTERNS OF NEW URBAN DEVELOPMENTS 34 PATTERNS OF NEW URBAN DEVELOPMENTS 2a/ INDIVIDUAL HOUSES, SINGLE-FAMILY HOMES Description: Individual houses on plots of approx. 500 sq m Freestanding or semi-detached 1-3 storeys Plot coverage 17% Distance b. buildings 6 m lateral Floorspace density approx. 0.2 Flats/hectare 16-30 According to surveys, single-family homes are widely regarded as the ideal housing type. However, freestanding single-family homes are the building type with the highest land consumption. Hence their viability in urban areas is limited and hard to defend. Due to low development density, the public cost of creating access routes and supply and disposal infrastructure is above average. High share of individual motorised traffic; long distances to infrastructure facilities.

Situation within the city The project is situated at the southern periphery of Bratislava in the suburb of Rusovce. While the distance from the city centre is 13 km, it can be reached in only 20 minutes by car or bus. Public transport connections are good, since bus stops can be found at 200-600 m, and a train station, at approx. 500 m. Social infrastructure and a good selection of shops can only be reached by bike or car (at 1.5 km in Rusovce proper). Location assets The project itself and the borough of Rusovce combine the advantages of living in the countryside with quickly accessible cultural and community facilities typical of the city. Being close to water bodies (lakes, Danube canals) and the Danube cycling track, the area is a popular and attractive leisure magnet. Prerequisites of success The location is so attractive (e.g. good traffic and transport connections, recreation areas, green zones) that the property proved easy to sell. The objective lay in making maximum use of the plot. The project type presents ambitious challenges regarding both technical and transport infrastructure. Quality and flexibility of use of individual structures Nové Rusovce is a purely residential complex. Every unit faces all directions. The architectural type chosen corresponds to that of a single-family house offering maximum privacy and intimacy. Due to this design, interior spaces can be optimised in harmony with the exteriors (e.g. gardens face south, garages face north). Availability and quality of open spaces Apart from the private gardens, there are no semi-public or public open spaces, only access and exit routes. Car parking slots are situated individually on each property. Neighbourship, communal facilities Due to the single-family home character of the project, a sense of neighbourship can evolve solely through direct contact with the inhabitants of adjoining properties. There are no communal facilities. Quality of urban space As a result of its low height, the development is visually discreet but functionally and structurally rather monotonous and lacks intermediate stages between public and private spaces, which hampers the emergence of both a feeling of neighbourship and urban appeal. 36 PATTERNS OF NEW URBAN DEVELOPMENTS 06/ Nové Rusovce (Bratislava – Rusovce, Pri gaštanovej aleji) Reference surface, hectares Net plot surface, hectares 4.27 3.65 Built-up surface, hectares Lot coverage ratio, % 0.62 17 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % Floor area ratio, gross Floor area ratio, net Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % direct medium 1-3 1.9 8,212 100 0 0 0.19 0.22 8,212 54 152 14.8 12.6 54 100 owner-occupied 0 36,500 0 17 83 0 Circulation areas, sq m 6,153 Aboveground parking, sq m 0 Number of slots 107 Type of parking open-air slots, indiv. garages on the plots Service infrastructure costs/dwelling high Year of completion 2000-2003 37 PATTERNS OF NEW URBAN DEVELOPMENTS 38 PATTERNS OF NEW URBAN DEVELOPMENTS 2b/ INDIVIDUAL HOUSES, “TOWN VILLAS” Description: Freestanding individual buildings facing in all directions; number of (residential) units served by one vertical access core is maximised 3-8 storeys Plot coveragee 22-26 % Mean distance b. buildings 13-18 m Wing depth 10-30 m Number of storeys 3 3+T 4 5 8 Floorspace density 1,1 1,3 1,8 2,2 Flats/hectare 90 110 120 150 165 1,4 There are various embodiments of the freestanding individual house as building type: from minimal building density exemplified by freestanding, 1- to 3-storey single-family homes to 3- to 5storey town villas as shown above and high-rise clusters with high floorspace density. In contrast to typical urban blocks, this design has no “inside”, “outside” or main orientation, which calls for sensitive handling of the transition zones. Pros: adaptability to different plot layouts; avoidance of largescale architecture; possibility of design variety if projects are entrusted to several architects and/or developers. Possible cons: if the distance between buildings is small, this impacts privacy; some flats only face north; protection against street noise is poor.

(Bratislava, Drotárska ul.) In brief The urban villas in Drotárska Street with a view of Bratislava were built in the late 20th century. This group of nine five-storey residential buildings is arranged in a circle around the access road. Situation within the city The complex is situated on the slope of Machnáč Hill slightly outside the old city centre of Bratislava and difficult to reach by public transport. In this area, easy mobility definitely requires car use. The complex and its direct surroundings feature some basic infrastructure (crèche, kindergarten, elementary school, grocery stores). Location assets Close to city centre and Horský Park (gardens), hillside position with pretty city view. A multifunctional building complex will soon be erected in the immediate vicinity. Genesis and prerequisites of success The shape of the ensemble with its point blocks arranged in a circle makes good use of attractive features of the natural environment and acts as a prerequisite for the further spatial and functional enlargement of the complex. Quality and flexibility of use of individual structures Big balconies on every floor and the unconventional, arched top-storey roofing are special architectural characteristics. The flats face east/west. Communal facilities are minimal; the complex itself does not offer shops or other social infrastructure amenities. Availability and quality of open spaces The buildings boast large balconies on every floor and loggias for the top-storey units. Circulation within the complex is provided by a wide ring-road. Meadows between the point blocks are partly defined as children’s playgrounds. Due to the ample space available, the possibilities of use are varied. Cars are parked either in underground garages, along the ring-shaped access road or on parking lots. Neighbourship, communal facilities Overall, the point blocks arranged around the central circular ring-road create a pleasant housing environment that fosters a sense of neighbourship. Communal facilities fulfil only minimal standards, which falls short of the high quality of the flats themselves. Neighbourship appeal can emerge due to varied spatial qualities. Quality of urban space Despite its mono-functionality, the complex enters into synergy with the environs and hence offers high living quality in a beautiful location surrounded by greenery. The physical (by car, on foot) and visual permeability of the settlement enhances urban space. 40 PATTERNS OF NEW URBAN DEVELOPMENTS 07/ Drotárska ul. (Bratislava, Drotárska ul.)

The residential streets are quiet due to traffic calming; the individual structures are small-scale and low-rise (maximum four storeys). Narrow open spaces extend between the buildings. Situation within the city The estate is situated at approx. 9 km from the city centre in a quarter on Zijkanaal I with its narrow green corridors along the water’s edge. A bus stop is located at a distance of 300 m. Social infrastructure and shops for daily necessaries will be provided in future, not yet constructed phases of the overall project. Location assets Location on the water’s edge, close to green spaces (north of the canal, to be reached via a new bike tunnel currently underway). Further green spaces along the canal are planned. Prerequisites of success The settlement is the first phase of a “21st-century garden city” (as defined by its planners). So far, 150 housing units have been built; the overall concept provides for a total of 1,300 to 1,400 rented and owner-occupied flats. A good social mix is essential – 30% of the flats are state-subsidised; additional facilities for seniors are envisaged. Quality and flexibility of use of individual structures Depending on the building type, the flats face in different directions. Density is relatively high, with two to eight units per house. All structures are small-scale. Due to the designs chosen (single-family, duplex and multi-family dwellings), flexibility of use is practically nonexistent. Availability and quality of open spaces The combination of low-rise buildings with high density allows for only minimal individual open spaces. Some distance spaces between buildings are extremely tight. Due to ground-floor parking slots, cars are very visible. There is a small playground for use by residents, yet no areas designated for teens. However, the open spaces along the canal are generously designed. Neighbourship, communal facilities A sense of neighbourship emerges by necessity due to high densification (glimpses inside neighbouring flats due to minimal clearance between houses) but is limited to next-door neighbours. The only communal facilities are a very small children’s playground (for kids aged up to 6 years) and a small square. The canal offers infrastructure for houseboats. Quality of urban space Traffic calming in the residential streets ensures good quality of urban space. 42 PATTERNS OF NEW URBAN DEVELOPMENTS 08/ De Bongerd (Amsterdam Noord, Moestuinlaan) Reference surface, hectares Net plot surface, hectares 2.52 2.00 Built-up surface, hectares Lot coverage ratio, % 0.72 36 Wing depth, m Access type 10.5-14.5 DH, SP medium 3-4 3.1 Façade distance Number of storeys Mean number of storeys Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 22,000 100 0 0 Floor area ratio, gross Floor area ratio, net 0.87 1.10 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m 17,000 151 (40 houses) 72-144 113 76 60 151 84 0 16 owner-occupied/rented 0 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 8,650 0 15 83 2 Circulation areas, sq m 2,800 Aboveground parking, sq m 1,100 Service infrastructure costs/dwelling high Number of slots 174 Type of parking individual+open-air slots Year of completion Planner Developer 2000 Rudy Uytenhaak City of Amsterdam, ODP 43 PATTERNS OF NEW URBAN DEVELOPMENTS 09/ Siedlung Ruggächern (Zürich, Affoltern) In brief The densely built-up estate Ruggächern is composed of point blocks and rows of houses along a train line. The individual structures with their red brick façades present a homogeneous look and feature high appointment standards. Flat types are varied and spacious, with attractive communal facilities. A good social mix is aimed for. Situation within the city The development area Ruggächern in Zurich-Affoltern is situated at approx. 8 km from the city centre. A bus stop and the commuter train station Zurich-Affoltern are located directly south of the settlement. Social infrastructure and a good range of shops can be reached on foot. A school complex adjoins the settlement. Location assets Public transport connections are excellent due to the commuter train station situated directly south of the complex. Prerequisites of success The settlement Ruggächern creates an independent architectural gesture between the densely built-up surrounding area and the open spaces in the environs. Despite their high quality, rented flats are affordable. Quality and flexibility of use of individual structures The quarter was exclusively planned for residential purposes. A good social mix was aimed for not only at settlement level but rather within individual houses as well. Flats face two directions (corner position) or one direction only, while the buildings as such face all four directions. There are no flats on the ground floor. Half of the 278 units are spacious family flats with four big rooms and one small room. A total of 34 units are available for seniors or singles. Individual rooms for rent are also on offer. One building is especially geared towards the needs of seniors. Flexibility of use is partly provided by communal facilities on the ground floor and by the individual rooms for rent. Availability and quality of open spaces Every flat has its own private open space (loggia). Open spaces are ample and car-free. The settlement boasts two squares and several playgrounds. Cars can be parked along the train line and in underground garages. The communal rooms are always connected to the open spaces outside; areas were designated for young people to meet and play. Neighbourship, communal facilities A sense of neighbourship can emerge both in the buildings (contact on the stairs) and open spaces. Special facilities such as communal rooms with a kitchen, a health and wellness zone, a library with Internet corner and guestrooms at the ground-floor level of the perimeter buildings are available. This family-friendly settlement also features a daycare nursery. Quality of urban space With its open perimeter zones and generously sized courtyards, the project is characterised by an appealing urban quality. 44 PATTERNS OF NEW URBAN DEVELOPMENTS 09/ Siedlung Ruggächern (Zürich, Affoltern) Reference surface, hectares Net plot surface, hectares 3.78 3.38 Built-up surface, hectares Lot coverage ratio, % 0.80 24 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 16.5 SP, LG medium 4-7 5.9 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 47,300 99 0 1 Floor area ratio, gross Floor area ratio, net 1.25 1.40 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % 27,850 278 40-122 100 82 74 278 0 100 0 Housing tenure Non residential use, sq m rented 1,000 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 19,100 0 90 0 10 Circulation areas, sq m 5,570 Aboveground parking, sq m 420 Service infrastructure costs/dwelling medium Number of slots 210+22 Type of parking TG + open-air slots Year of completion Planners Developer 2007 Baumschlager/Eberle ABZ–Allg.Baugenoss.Zürich 45 PATTERNS OF NEW URBAN DEVELOPMENTS 10/ Wohnhäuser am Mühlweg (1210 Wien, Mühlweg 74-78 / Fritz-Kandl-Gasse 1-11) In brief The estate takes the form of a multi-storey residential project designed as solid-timber or mixed timber-solid masonry “town villas” with small-scale, car-free open spaces. The choice of materials aims for moderate energy consumption. Situation within the city Situated at the northern periphery of Vienna in the 21st municipal district with a commuter train station (Strebersdorf) at 800 m, tram and bus stops at 500 m and the nearest hook-up to the A22 (Danube Riverbank motorway) at 1,000 m from the development. Schools, kindergartens and shops for everyday necessaries can be found in the village of Strebersdorf at only 500-1,000 m distance. Location assets The project is situated directly along a green belt (Marchfeld Canal) to the east and a road with traffic calming (Mühlweg) to the west. Prerequisites of success Outcome of developers’ competitions, embracing three lots, for multi-storey timber structures designed as low-energy or passive houses. Quality and flexibility of use of individual structures Depending on their position within the respective building, the flats face one, two or three directions. Due to small unit sizes and storey heights, flexibility of use is largely absent. Availability and quality of open spaces The open spaces of the development are small-scale, manifold and may embrace the whole range from public to private. However, the proportions of these open spaces differ intentionally from lot to lot. Smaller open spaces for communal use are available. Neighbourship, communal facilities Circulation routes within the development (small number of flats per building entrance) and manifold open spaces foster a sense of neighbourship. There are no specially designated areas for use by young people; except for one lot, all communal facilities only correspond to the minimum stipulated under law (rooms for parking prams and bikes, general-purpose storage room). Quality of urban space No car traffic within the blocks; pedestrians can cross the project to reach the green corridor beyond. 46 PATTERNS OF NEW URBAN DEVELOPMENTS 10/ Wohnhäuser am Mühlweg (1210 Wien, Mühlweg 74-78 / Fritz-Kandl-Gasse 1-11) Reference surface, hectares Net plot surface, hectares 2.57 2.14 Built-up surface, hectares Lot coverage ratio, % 0.75 35 Wing depth, m Access type 12-22 LG, MG, central Number of storeys Mean number of storeys Façade distance Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 3+T / 4+T 4.0 medium 30,000 100 0 0 Floor area ratio, gross Floor area ratio, net 1.17 1.40 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m 22,526 252 60-130 89 118 98 252 22 68 10 rented/owner-occupied 0 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % Circulation areas, sq m Aboveground parking, sq m Service infrastructure costs/dwelling Number of slots Type of parking 14,150 0 68 22 10 0 0 low 252 TG Year of completion 2006/07 Planners H.Kaufmann, Riess, D.Untertrifaller Developers BWS, Arwag, BAI 47 PATTERNS OF NEW URBAN DEVELOPMENTS 11/ Karree St. Marx C (1030 Wien, Erne Seder Gasse 2-8 / Viehmarktgasse 1A-1B) In brief Six point blocks set among a park-type environment shielded from the road by an Lshaped perimeter structure. To the northwest, the project composed of residential units, a kindergarten and shops adjoins an “urban wilderness”, which is continued by the architectural design chosen. Resting atop glazed or open ground-floor zones, the structures seem to float. The visual impression of an unbroken cityscape is preserved. Situation within the city This project situated 4 km southeast of Vienna’s historic centre is part of a plan to develop the former slaughterhouse yards of St. Marx and hence should be classified as an “inner-city urban expansion” venture. Distances to tram and bus stops are 100-200 m; to the nearest Underground station, 600 m. Car access is provided via roads on two sides of the property. The social infrastructure and range of shops to be found on a major road west of the development and around the Underground station correspond to the city location. Location assets Location close to historic centre, topographically slightly raised vis-à-vis the adjoining northwestern lot, an “urban wilderness” that serves for leisure and recreation. Prerequisites of success Karree St. Marx C was implemented together with three separate teams of architects on the basis of an urbanistic master project (developers’ competition). The effect of heavily trafficked Schlachthausgasse west of the project is still palpable, but it is planned to shield the residential section by means of a block containing offices and shops. Quality and flexibility of use of individual structures The flats face the surrounding green zones on all sides. All units have spacious balconies; many flats occupy corner positions. The ground floor of the L-shaped perimeter structure accommodates a large unit designed for a flat-sharing community. The development boasts a kindergarten and three shops. The central access zone is well-lit. Flexibility of use of the ground-floor zones is ensured by generous room heights and building depth. Availability and quality of open spaces The entire project is characterised by a pleasant balance of built volumes and open spaces. Private open spaces such as balconies are provided. The settlement is permeated by greenery, is accessible for pedestrians from outside and offers generous spaces for appropriation by young people. Neighbourship, communal facilities A sense of neighbourship is likely to develop due to the generously sized communal facilities (children’s playrooms) and open spaces of the project. All ground-floor zones of the point blocks are dedicated to communal facilities. Quality of urban space The entire project is publicly accessible for pedestrians and directly adjoins a nature park-style “urban wilderness”. 48 PATTERNS OF NEW URBAN DEVELOPMENTS 11/ Karree St. Marx C (1030 Wien, Erne Seder Gasse 2-8 / Viehmarktgasse 1A-1B) Reference surface, hectares Net plot surface, hectares 2.94 2.67 Built-up surface, hectares Lot coverage ratio, % 0.76 28 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 15/28-30 SP/central wide 6-9 7.2 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 55,000 96 2 2 Floor area ratio, gross Floor area ratio, net 1.87 2.06 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % 35,355 406 41-112 87 152 138 406 0 95 5 Housing tenure Non residential use, sq m rented 1,110 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 19,072 0 92 3 5 Circulation areas, sq m Aboveground parking, sq m Service infrastructure costs/dwelling Number of slots Type of parking Year of completion Planners Developers 0 0 low 430 TG 2010 Prohazka, Querkraft Geiswinkler&Geiswinkler ÖSW, Bauhilfe, Sozialbau 49 PATTERNS OF NEW URBAN DEVELOPMENTS 12/ Wohnsiedlung Werdwies (Zürich, Grünauring / Bändlistraße) In brief The residential development Werdwies is a settlement composed of four free-standing, eight-storey point blocks and three buildings with air wells and was constructed following the demolition of a 1950s settlement. Integrated infrastructure facilities and public housing subsidies for the flats safeguard high quality of use. Situation within the city The suburb of Grünau is situated close to 6 km from Zurich Main Station near Limmat River. The housing development Werdwies is easily reached by public transport (only 20 m to tram and bus stops and 600 m to the nearest commuter train station). The condensed structure of this suburb allows for social infrastructure and a good range of shops within walking distance. Location assets Excellent connection to public transport network; proximity to urban recreation zone along Limmat River. Prerequisites of success The housing development Werdwies – the outcome of an architectural competition and the commitment of one housing developer – was to meet a high level of energy efficiency close to passive house standards. The innovative implementation concept also included identity-creating intermediate utilisation of the property (artistic interventions) between the demolition of the previous buildings and the construction of the new project. Quality and flexibility of use of individual structures Many of the 152 flats occupy a corner position and hence boast views of the city from two directions. The building arrangement safeguards particularly favourable lighting and minimal shading. The ground-floor zone integrates a bistro, supermarket, kindergarten and crèche as well as small service providers and studios, thus ensuring high flexibility of use. Availability and quality of open spaces All flats have loggias. Due to their position, the character of the settlement’s open spaces is public, highly attractive and appealing. Children and young people find play equipment scattered across the open spaces. Cars and bikes can be parked underground and on a one-storey covered parking lot. Neighbourship, communal facilities Neighbourhood communication is facilitated by the building lobbies. The development also features communal rooms and music rooms. Every floor of the point blocks boasts a soundproofed music room. Quality of urban space Good spatial quality is ensured by the ground-floor zones, whose shops and service providers are easily accessible on foot, as well as by the streetscape of the project. 50 PATTERNS OF NEW URBAN DEVELOPMENTS 12/ Wohnsiedlung Werdwies (Zürich, Grünauring / Bändlistraße) Reference surface, hectares Net plot surface, hectares 2.04 1.69 Built-up surface, hectares Lot coverage ratio, % 0.49 29 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % Floor area ratio, gross Floor area ratio, net Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % 17-37 SP wide 1-8 6.4 31,300 1.53 1.85 16,430 152 66-154 108 90 75 152 0 100 0 Housing tenure Non residential use, sq m rented 2,030 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 13,680 0 51 26 23 Circulation areas, sq m 580 Aboveground parking, sq m 340 Service infrastructure costs/dwelling medium Number of slots Type of parking TG + open-air slots Year of completion Planners Developer 2007 Adrian Streich City of Zurich 51 PATTERNS OF NEW URBAN DEVELOPMENTS 52 PATTERNS OF NEW URBAN DEVELOPMENTS 3a/ 2- TO 4-STOREY LINEAR DEVELOPMENTS Description: Oblong, narrow volumes set closely side by side; ground-floor flats with gardens 2-4 storeys Plot coverage 34-44% Distance b. buildings 12 m Wing depth 6-20 m Number of storeys 1-2 2+T 3 3+T Floorspace density <1.0 1.3 1.4 1.8 Flats/hectare <100 110 120 140 Linear ribbon-type developments with narrow volumes are both well-suited for low row houses and multi-storey buildings.

The ground-floor flats have their own front gardens; those on the floor above feature balconies, while the top-floor units boast terraces. The complex is part of a larger development, with which it shares a children’s playground and an underground garage. Situation within the city The project forms part of an urban expansion zone along the northeastern periphery of Vienna and, surrounded by single-family homes, occupies a long and narrow plot typical of the Marchfeld Plain. On one side, the complex is accessed by a public road that is also used by a bus line. The village core of Aspern with social infrastructure (school) and a variety of shops can be found at a distance of approx. 900 m. Location assets A public park with play areas for younger and older children is situated north of the project. Prerequisites of success Exemplary low-rise, condensed settlement with ample green spaces at the urban periphery. Quality and flexibility of use of individual structures All 110 housing units face east/west and have their own open spaces (front gardens, balconies, roof terraces). The ground-floor units resemble terraced single-family homes. All units moreover disclose views of the surrounding greenery. Due to its terraced-house character, the complex presents but little flexibility of use. Availability and quality of open spaces The open spaces extending between the rows and offering access to the individual buildings are atmospheric and provide space for children to play and spend time in. The two-row complex composed of ten identical blocks is centrally accessed via a footpath, with intersecting lanes in-between connecting it to the road. Neighbourship, communal facilities There are no communal facilities. The sense of neighbourship is fostered by the adjoining gardens. Young people find space to meet and play in the adjacent park. Quality of urban space While publicly accessible, the central footpath is predominantly used by inhabitants – an effect of the purely residential character of the complex. 54 PATTERNS OF NEW URBAN DEVELOPMENTS 13/ An den alten Schanzen (1220 Wien, Soldanellenweg 4) Reference surface, hectares Net plot surface, hectares 1.63 1.13 Built-up surface, hectares Lot coverage ratio, % 0.48 42 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 14.5 SP medium 2+T 2.6 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 12,380 100 0 0 Floor area ratio, gross Floor area ratio, net 0.76 1.10 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m 110 36 37 27 owner-occupied 0 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % Circulation areas, sq m Aboveground parking, sq m Service infrastructure costs/dwelling Number of slots Type of parking Year of completion Planners Developer 9,000 110 60-100 82 98 68 6,480 0 51 49 0 0 0 low 110 TG 1994 Marschalek, Ladstätter Wohnungseigentum 55 PATTERNS OF NEW URBAN DEVELOPMENTS 14/ Erzherzog-Karl-Stadt B (1220 Wien, Annie-Rosar-Weg 1-3) In brief The project is a row-type development with narrow volumes and composed of twostorey terraced houses with only minimal depth and small spaces between the blocks. Both ground-floor and upper-storey units have their own gardens (at ground-floor level, with direct access from the flats including those on the upper floor). Urban quality is solely derived from the environment and the proximity of the settlement to the centre of the city quarter. Situation within the city This housing complex is part of Erzherzog-Karl-Stadt, a residential development in Vienna’s 22nd municipal district. The distance from the nearest bus stop is approx. 100 m; that from the nearest tram stop, approx. 300 m. Social infrastructure (kindergartens, elementary schools) and shops for everyday necessaries can be found both in the quarter itself and in the nearby village core of Aspern. Erzherzog-Karl-Stadt is a car-free zone for pedestrians and covers a surface of roughly 10 hectares. Location assets Protected position shielded by row buildings that block the noise from the nearby street. Part of a larger urban development area. Prerequisites of success This settlement type shows how the housing quality offered by single-family homes can be implemented even in a condensed terraced-house project. Quality and flexibility of use of individual structures Strictly residential project. The flats all face their individual gardens. The east/west alignment ensures good housing quality. Flats are not designed as maisonettes but extend over one storey only. Flexibility of use was obviously not aimed for. Availability and quality of open spaces Apart from the necessary access paths, there are no open spaces for communal use. However, the private gardens offer ample green zones. While the project itself does not provide space for young people to play and meet, these exist in the close vicinity. Neighbourship, communal facilities Neighbourship is fostered by the fact that all flats have their own garden, which stimulates communication. There are no communal facilities. Quality of urban space While the complex as such conveys an impression of mono-functionality, the fact that cars are banned from the development ensures permeability for pedestrians, also from outside. 56 PATTERNS OF NEW URBAN DEVELOPMENTS 14/ Erzherzog-Karl-Stadt B (1220 Wien, Annie-Rosar-Weg 1-3) Reference surface, hectares Net plot surface, hectares 1.13 0.98 Built-up surface, hectares Lot coverage ratio, % 0.33 34 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 6.1 RH, direct narrow 2 2 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 6,542 100 0 0 Floor area ratio, gross Floor area ratio, net 0.58 0.66 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface 5,113 77 64-87 66 79 68 Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % 77 100 0 0 Housing tenure Non residential use, sq m rented 0 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % Circulation areas, sq m Aboveground parking, sq m Service infrastructure costs/dwelling Number of slots Type of parking Year of completion Planners Developer 6,500 53 0 45 2 0 0 medium 77 TG 1998 Katzberger, Loudon Neues Leben 57 PATTERNS OF NEW URBAN DEVELOPMENTS 15/ Beddington Zerobed (London, Beddington) In brief Beddington Zerobed is a quarter composed of six one- to three-storey row volumes. This settlement type provides an optimised combination of ecological housing and working with high quality of life. The highly condensed, low-rise townhouse design reinterprets the English garden city. The communal centre “BedZED Pavilion” has acquired regional importance. Situation within the city Beddington Zerobed is situated in the borough of Sutton at 14 km distance from London’s city. A bus stop is situated directly adjacent to the development, while a suburban train station can be found at only 600 m from the complex. “Green transport schedules” and car sharing promote a new mobility concept. The nearest supermarket is at 2 km; a twice-weekly local farmers’ market offers additional shopping possibilities. Location assets Recreational area to the northeast of London. Prerequisites of success Following land rehabilitation, Beddington Zerobed was constructed on a former sewage works site. The underlying concept aims at “green lifestyles“: use of natural materials such as brick and certified timber; aerodynamic design and rooftop ventilators to improve ventilation without air-conditioning units; heating provided by a cogeneration plant (fuelled by locally produced biomass); solar panels on roofs; sustainable water use; own water treatment plant; greywater used for toilet flushing. In keeping with these standards, the original investment costs were high. The project is composed of social housing, rented apartments and owner-occupied flats for one third each. Quality and flexibility of use of individual structures The project creates possibilities of combined living and working in one building. Flatscum-studios, terraced houses, attic flats and one-level apartments are available. Flats face south (optimised energy consumption), while studios face north. The individual wings are relatively deep (up to 20 m) and compact. Flexibility of use is provided by the ground-floor studios. Densification ensures supply with everyday necessaries and a wider range of shops and service providers within walking distance. Availability and quality of open spaces The development boasts a differentiated range of private open spaces (resident gardens, terraces, roof terraces, balconies). Traffic calming was introduced for the residential streets; a village green fosters communication. There are also spaces for young people, e.g. a sports pitch. Neighbourship, communal facilities Both open spaces (sports pitch, village green) and buildings offer communal facilities (clubhouse, community centre/BedZED Pavilion, kindergarten and gyms). Quality of urban space Due to the architectural design, the open spaces are very introverted and hence of little attractiveness for the surrounding city quarter. 58 PATTERNS OF NEW URBAN DEVELOPMENTS 15/ Beddington Zerobed (London, Beddington) Reference surface, hectares Net plot surface, hectares 0.93 0.83 Built-up surface, hectares Lot coverage ratio, % 0.35 42 Wing depth, m Access type Façade distance Number of storeys Mean number of storeys 12.5-20 RH, SP narrow 1-3 2.3 Gross floorspace, sq m Of which housing, % Of which work, % Of which services, % 8,000 74 20 6 Floor area ratio, gross Floor area ratio, net 0.86 0.96 Total useful living area, sq m Number of dwellings Flat sizes, sq m Average flat size Flats/hectare of plot surface Flats/hectare of reference surface Flats with open space Of which with private garden, % Of which with balcony, loggia, % Of which with terrace, % Housing tenure Non residential use, sq m 5,290 63 84 76 68 - owner-occupied/ rented 400 Total open spaces, sq m Of which public, % Of which semi-public, % Of which private, % Of which children’s playgrounds, % 2,430 0 12 72 16 Circulation areas, sq m Aboveground parking, sq m Service infrastructure costs/dwelling Number of slots Type of parking 2,950 510 medium 44 open-air slots Year of completion Planner Developer 2002 Bill Dunster Peabody Trust 59 PATTERNS OF NEW URBAN DEVELOPMENTS 60
