• Max-Becker-Areal, Cologne

    The 17,3 ha site is currently isolated from the urban space and polluted with emissions. The environment is characterized by deficits in the open space and local supply with green spaces and represents a structural and programmatic caesura in the otherwise small-scale district structure of Ehrenfeld.

    With the „Best-Of Ehrenfeld" an open quarter with a strong character is created, which combines a high urban density with open, diversely networked and richly programmed open spaces. It is a Cologne Veedel (Kölsch for „quarter") in the best sense of the word: living, working, culture and education are fused in small spaces and linked with each other over short distances. The mix of uses is derived from the urban planning concept at the construction site level. The new district is green, culturally anchored and creatively attractive.

    The urban development forms a structural and programmatic bridge between the districts of Ehrenfeld, Müngersdorf and Braunsfeld. Urban density and diversity meet a green network with a wide range of offers and possible uses.

  • Recyclinghaus, Hanover

    The recyclinghouse is an experimental residential building in the Hanover district of Kronsberg. It is a prototype that tests the possibilities and potentials of various types of recycling in the real laboratory and shows a cycle-oriented and resource-saving planning approach.

    On the one hand, the recycling center relies on recyclable building products, such as the raw construction made of glue-free solid wood elements. On the other hand, recycled materials such as the foundation made of recycled concrete or wall insulations made from old jute bags are used. There are also large quantities of used components being used which, if possible, originate from the building stock of the client GUNDLACH or have been obtained locally. Particularly important is a recycling-fair design that allows the use and disassembly of the components without loss of quality or a sorted separation of the materials after the end of life.

    The construction industry is one of the largest waste producers and consumers of resources and a significant contributor to global CO2 emissions. When planning buildings, today it is mainly the energy consumption in the operation of a building that is considered. The considerable amounts of "gray energy" involved in the production of buildings remain largely unconsidered. Here, the existing building stock can also be understood as huge raw material storage. The recycling of building materials and materials as well as recycling-friendly construction methods will play an increasingly important role in the future.

  • Parkway, Heidelberg

    „Think about people first, then about traffic routes. A good city is like a good party. People stay there longer than necessary because they feel good." This quote from Danish urban planner Jan Gehl sums up our planning understanding of the Parkway well.

    The Parkway is a place that is finely networked, that relates building and open space uses in a variety of ways, and that actively supports climate resilience. A green and diverse space that constantly links the opposites of MOBILITY and DISTURBANCE. Due to the valuable and spatially defining existing trees in the Patrick Henry Village as a starting point, the route was designed in such a way that as many woody plants as possible are preserved. Rainwater is stored in swales, infiltration trenches and rain gardens as a valuable resource, benefiting plants and groundwater. The paved areas are reduced to a minimum and designed as light-coloured surfaces.

    The paving material is a newly developed and market-introduced climate stone which absorbs rainfall and can evaporate as much water as a meadow surface (50% instead of 11% to 18% as with conventional paving stones).
    The Parkway fulfils the function of a linear park with a high quality of open space, encounter and stay, serves as an inner and outer distributor for the Patrick Henry Village and provides a safe framework for a broad variety of urban mobility types.

  • Framework plan Hafenband+, Flensburg

    maritime. green. communal.

    The framework plan for the Hafen-Ost (harbour east) quarter in Flensburg forms the basis for the development and transformation of Hafen-Ost into a climate-friendly and sufficiency-oriented city neighbourhood with mixed uses and a wide range of open spaces.

    Based on three possible development scenarios, a cooperative development process was carried out to create the framework plan involving the city, politics, stakeholders and the population. The result is the synthesis scenario "Hafenband + maritime. green. communal.", which creates the basis for the framework plan.

    In addition to the framework plan with an urban and landscape planning concept, a development and utilization concept and an integrated mobility concept, the focus under the topic "How will less be enough?" is on the development of a sufficiency quarter for approx. 1000 units and up to 2,000 AP in an inner-city location.

  • Düsseldorf Mosaic

    How can Düsseldorf react to demographic change? Who plays which part in current urban development processes? Where can we create affordable living space? How far away is the open countryside, the nearest playground? These and many other questions concern the citizens of Düsseldorf. The "Raumwerk D", which is being developed parallel to the "Mobility Plan D", is intended to provide answers to such questions that have been worked out together. The spatial image determined within this framework is not a plan in the conventional sense. It is based on the current state of urban and landscape spaces and emphasises structural elements. It marks identity-defining places as well as urban structures that take over important functions for orientation. Furthermore, it spatially and pictorially highlights the qualification and profiling of urban spaces and the focal points of urban development. The participants in the dialogue process have enriched and specified the spatial image with suggestions regarding content and illustration.

  • Residential Crown Windmühlenstraße, Hanover

    The residential crown is a prototype of settlement 2.0. Rooftops of retail and office buildings, as well as parking garages, are activated, attractive locations are opened up, existing infrastructures are used more efficiently and the mixture of programs in the city centre is improved. The existing parking garage is complemented with penthouses as part of the renovation of the façade and entrance area. These residential units distinguish formally from the existing building structure and simultaneously give the building a harmonious completion.

    Entrances and circulation of the building have been reorganized so that independent addresses for the car park and the residential building are clearly recognizable. The residential building is accessed (barrier-free) via a representative lobby on the ground floor with exclusive elevators that lead directly to the central, landscaped residential courtyard. The residential units are accessible from this common space. Each apartment (50 to 120m²) has a spacious, private terrace overlooking the rooftops of the city.

  • ecovillage - Tiny Living, Hanover

    Sufficiency means shared luxury.

    The "Tiny Living" building is part of our project ecovillage in Hanover. It is located at the transition between the centre and the Green Ring and forms the interface between the intimate neighbourhood and communal space with a high degree of publicity.

    The L-shaped building consists of two stepped structures, which are accessed and connected via a generously usable arcade. On the one hand, the arcade enables a diverse exchange between the residents and, on the other hand, a very high degree of flexibility in the use of the building. Based on a grid, a wide variety of apartment sizes and forms of living can be offered and the living space can be adapted to future changing needs.

    The main focus in the development of "Tiny Living" is residential use. This is supplemented by a shared bicycle and storage room, two laundry rooms, a common room and an experiment room for water use and food cultivation operated by the entire ecovillage with access to the adjacent aquaponics greenhouse.

    Responsible use of building materials makes a significant contribution to the sustainability of the property. As early as the construction of the building, the conservation of natural resources is included through a design that is suitable for recycling. Through the targeted choice of materials and the possibility of a clean separation of the elements used, the amount of waste is reduced and the rate of reuse and recyclability increases. The greatest possible use of the renewable building material wood not only minimizes the CO2 emissions during the construction of the building but also serves as important CO2 storage.

    With the development of our ecovillage project in Hanover, there is a great opportunity to make an important contribution to future-oriented urban development with a balanced triad of social, ecological and economic sustainability. Find out more here.

  • Blue-green neighbourhoods, Münster

    The design taps into the potential to create a green, climate-adapted and carfree district for Münster Hiltrup that blends harmoniously into the existing landscape and settlement structure. Four compact neighborhoods with a large contact area to the open space will be linked by diverse green corridors in the interior (Green Delta) as well as a close-knit network of cycle paths and footpaths and attractively connected to the outside. Motorized traffic is reduced to a minimum and parking spaces are bundled. Within the neighborhoods, the mobility hubs form everyday hubs. A small-scale, differentiated development structure with ground floor uses at the neighborhood squares, social functions and various, mixed typologies suggest a people-centered scale with a rural character. In conjunction with an innovative climate adaptation concept and high ecological and energy standards, a future-oriented neighborhood development is being created for Hiltrup.

    Rainwater management follows the principle of the sponge city with the aim of minimizing intervention in the natural water balance, achieving near-natural rainfall-runoff behaviour, ensuring sufficient purification of the surface runoff that occurs, preventing flooding in the settlement area and reducing the runoff peaks into the watercourses to a natural level. Implementation is carried out as far as possible using near-natural methods with a small proportion of technical structures. In addition to the purely water management aspects, ecological benefits such as increased biodiversity and heat reduction are achieved. At the same time, blue-green structures are created that allow residents to experience the element of water.

  • Schamotte Quarter, Bonn

    From a factory site to a green living quarter!

    The concept for the area of ​​the former fireclay factory in Bonn-Duisdorf transforms the industrial site into a green neighbourhood with a high quality of living. The urban arrangement of the buildings is derived from the noise impact from the south and the location within a larger city block. A four-storey block building with a stagger along the railway line shields the quarter from the noise. Two polygonal, four-storey solitary buildings in the south form the transition to the more loosely arranged buildings in the area. The structurally identical buildings fit into their surroundings by being twisted against each other and creating diverse and exciting spaces through recesses and bends.

    A neighbourhood square is being created that will serve as an identity-forming address and meeting point. An additional green open space stretches to the east, where the opposite entrances to the buildings are located.

    All adjoining municipal and private plots of land in the east and west can be integrated into the urban picture. The existing building, a shelter for the homeless, can be retained and further developed by adding another story and balconies. The green connection in the middle of the quarter will be extended and merged with a green area with a playground. In the west, a solitary structure can provide a clear edge to the neighbourhood square and minimize the noise impact on the inside of the quarter.

    All new buildings are planned as wood hybrid buildings and can be recycled and later returned to the material cycle thanks to their deconstructability. Noise protection, spatial formation, and the quality of living are not dependent on the development of the neighbouring properties, guaranteeing a functioning and green residential area.

  • MAGNUM-Areal, Osnabrück

    The Magnum site's DNA of industrial heritage and landscape succession forms the starting point for the transformation into a climate resilient neighborhood. The unique character of the former steelworks is expressed spatially in the overlapping of the scales of human, machine and nature and of the atmospheres between narrow alleys and wide squares.


    This productive interplay continues to write the history of the Magnum site in constant change. Three subspaces (water courtyards, forest campus, factory cluster) derive from the site, each with its own independent profile, which form synergies with each other and with the neighborhood. The Magnum Mile connects the three subspaces as a lively backbone of the quarter and the adjacent urban spaces to the west and east.


    For the quarter, own systems for the handling of water and soil are developed. They will be used for irrigation, gray water utilization and cooling of the quarter. The goal is to minimize erosion and soil exchange. As much accumulating water as possible is to be collected, filtered and reused. To do this, it will be stored in building-integrated cisterns. Materials collected are reused as much as possible. Existing structures, such as the grove or also hall structures are integrated and the character of the open space and the building structures are developed. The transformation is designed as a gradual, learning and appreciativ process.

  • Circular quarters, Frankfurt

    CITYFÖRSTER has been unanimously selected for the design for the "Stadtteil der Quartiere" (district of the quarters)" in Frankfurt am Main, Germany with a concept that combines urban growth with circularity.

    The central challenge was how to create up to 10,000 apartments and 8,000 new jobs in an agricultural area on the northwest outskirts of Frankfurt, without losing the scenic qualities of this area. At the same time, the design also had to take into account various challenges; for example, like many peripheral metropolitan areas, the region is intersected by infrastructure - of which the six-lane Autobahn A5, which effectively divides the study area in two, has the greatest impact. A situation that is by no means exclusive to Frankfurt or even Germany, but can be found in most cities.

    One of the most remarkable choices was to keep 75 percent of the study area undeveloped, thus preserving the landscape and the connection to the Taunus. The design, which is based on the "Landschaf(f)tStadt" principle, consistently takes the possibilities offered by the landscape and the open space as a starting point.

    In order to protect as much of the landscape as possible, the development was kept in compact areas. This means, for example, the abandonment of single-family houses and the planning of mostly apartment complexes of five to six floors, occasionally even higher buildings. The underground and city railways form the backbone of the new districts; the expansion area "Steinbach-Ost" is directly connected to the existing S-Bahn line, and in the districts east of the Autobahn the metro network is being expanded. A number of the neighbourhoods will be car-free.

    The aim is to create circularly organized neighbourhoods - neighbourhoods as part of a cycle, in which they make an important contribution to water management, energy, and food supply, that promote environmentally friendly mobility, that regulate the climate and that enhance biodiversity - while naturally offering space for social exchange, providing a home to the community.

    All facts at a glance:

    4 new residential areas
    up to 10,000 apartments
    up to 8,000 new jobs
    5 schools
    20 nurseries
    47 hectares of public green within the neighbourhoods
    425 hectares of study area
    75% of the study area remains undeveloped

  • High Q, Hanover

    Urban integration creates a neighborhood
    In its immediate surroundings, HIGH Q picks up on the typological and urban development characteristics of its neighborhood. The existing principles of block structures, incisions and polygonal high points are transferred to HIGH Q in order to create a harmonious overall urban image.
    On the west side of the construction site, a neighborhood square with outdoor gastronomy will be created at the interface between the office and the hotel, creating a lively meeting place for everyone. This square also serves as an entrance to the hotel lobby.

    Striking appearance creates identity
    Whether viewed from a passing train, as a pedestrian or from a bicycle, the HIGH Q always looks different and yet is unmistakable. The special façade design with 6 partial façades makes the high-rise appear slender and without a rear side, creating ever new impressions.

    Recognition value and an identity-creating design are an important requirement for this building in this exposed location. On the one hand, the façade and the striking shape create a variety of impressions depending on the viewing angle, while on the other hand the building also offers diverse and special situations in its immediate context. The undercut to Celler Strasse with its forecourt forms a clear address, the neighborhood square offers a common center for the neighborhood and the differently designed facades improve orientation and create different places.

  • Klima-Mosaik, Fehmarn

    For the neighbourhood, a robust and at the same time adaptable concept is proposed, developed from the landscape and the context. Through a variety of qualified open spaces and a communal centre, neighbourhood, density and sufficiency can be thought differently.

    Approximately 250 residential units of varying design will be created in the neighbourhood. In order to create affordable housing, the focus is on multi-storey housing. With the building types row, point, angle and double, there are four variants of multi-storey housing in the neighbourhood. The diverse housing offer is complemented by 38 terraced houses. The neighbourhood cluster in the centre lends itself to cooperative development with complementary uses.

    The natural appearance of the neighbourhood is paramount. The use of sustainable materials offers ecological and technical advantages at the same time. Apart from the design specifications for typologies and spatial edges, the variance in facade and colour design, as well as in the open space elements of the individual neighbourhood clusters, ensures individuality and orientation. Design elements from the context create a sense of belonging to the surroundings, while communal spaces offer space for self-realisation.

    The "Klima-Mosaik" is characterised by strong open space references, diverse forms of housing and an active, communal neighbourhood centre (including a meeting place, co-working, special forms of housing). In addition, the neighbourhood hub bundles mobility services and other uses (e.g. workshop, parcel station, youth meeting place).

  • Karstadt Recycling, Berlin

    How can we transform vacant department stores in Germany and bring them to a new stage of life with new uses?

    Hundreds of department stores stand empty in German city centers. At Hermannplatz in Berlin, an old Karstadt building could be redesigned. A new façade creates a strong face in the urban context and an invitation to a differentiated courtyard sequence, which was redesigned as a playful open space experience. Instead of shopping, living, working and community-oriented offerings now meet the needs of the growing urban society in the 21st century.

    The existing Karstadt building provides valuable building materials that are deconstructed, recycled and reused. According to the layer principle, load-bearing and non-load-bearing components are structurally independent of each other. Thus, they can be used independently in their various life cycles.
    A durable, urban façade forms the new face to the city and creates a gateway to the interior.

    A varied sequence of courtyards accompanies the crossing and becomes an urban experience: the Werkhof with its lively hustle and bustle, the Green Heart as a central interface and at the same time as a place of retreat, and the city playground, which promotes interaction and participation. Flora and fauna form the connecting element of the spatial sequence within the courtyard structure up to the roof terraces.

  • Masterplan Wasserlagen, Herne

    The projected population development up to 2035 also shows the trend towards a housing shortage in Herne. Despite this development, vacancies and underused space potential characterize the waterfront area. Due to the strong commercial and industrial character of the area and the dominance of large infrastructures, the existing residential areas are exposed to high levels of noise pollution. A lack of open spaces and cultural facilities, difficult permeability for pedestrians and cyclists, as well as major weaknesses in local mobility, which is too strongly oriented towards private motorized transport, exacerbate the problem of isolated residential areas and the associated social imbalance in the area. Underused areas, vacancies and wastelands lack a coherent development perspective. Added to this are the deficient conditions in the housing offer and the external influences of the climate, energy and health crises with their very own challenges. This downward spiral must be counteracted by integrated and future-oriented planning for the entire area of the water locations. The planning objectives therefore focus on a diversified range of housing with a high degree of social diversity and programmatic mix; on the integrated development of high-quality commercial areas and the harmonization of housing, work, industry, open space, leisure and transport. A multimodal, transport connection and the structural, open-space networking of the entire area are the key factors.
