• ecovillage Hanover

    With the development of the ecovillage in Hanover, there is a great chance to make an important contribution to future-oriented urban development. One of the most specific features of the ecovillage, and its guiding principle, is sufficiency. To possess more by sharing more: a highly flexible approach that, here, is not only preached but also practiced. In addition to a co-working space and several workshops, ecovillage also offers common rooms in the buildings and gardens that belong to and can be used by everyone, and there is even a special guest house for visitors to stay the night.

    The nucleus of the urban design is the lively village square, that is surrounded and framed by the commons. This is the green heart of ecovillage; where water is being managed, food is being produced and the spirit of community is being lived.

    One of the drivers for the development was the ambition to become a CO2-neutral settlement. Everything is built from wood, and the sealing of the surfaces is being minimized as well. Biodiversity is promoted and gray- and rainwater are treated and cleaned with the help of a plant-based sewage treatment system. After being directed into a biotope-like lake, it seeps away and evaporates, or serves the residents to water their gardens.

    The mobility concept also sets high goals with regard to future viability: it focuses entirely on local mobility. (local public transport, as well as pedestrian and bike path traffic). In concrete terms, this means only 0.2 parking spaces per residential unit are provided. In return, however, there are generous areas for bicycles, rental stations, handcarts, etc. A direct connection to the light rail system rounds off this concept.

    The neighbourhoods, which are connected to each other and to the centre by the commons, consist of differently sized clusters. These clusters comprise various building typologies, which in turn provide space for a wide range of apartment forms. This 'democratic' housing mix promotes social integration and creates strong neighbourhoods.

    ecovillage can be regarded as a pioneer in a long-overdue discussion of principles in which frugality is pursued as a philosophy.

  • Recycling house

    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.

  • Blankenburger Süden - Circular City

    The design is based on the concept of a "Circular City", a circular organised neighbourhood, and is guided by the spatial principle "Landschaf(f)tStadt": The landscape creates the city.

    A structural and design focus is on the blue-green infrastructure: a 60-hectare landscape park with garden, forest and water land not only offers various places for leisure, sport and recreation but also provides numerous ecosystem services such as climatisation in urban areas, rainwater management, food production and the strengthening of biodiversity.

    The neighbourhood is divided into four sub-sections, each with its own specific building and open space structure. All buildings open up to green space and offer a variety of affordable housing options. Construction with wood and recycled materials and the creation of blue-green roofs contribute to the neighbourhood's good climate balance. A new type of building, the so-called CYC Hub, acts as a circulation interface. It houses the technical infrastructure of the circular organised neighbourhoods - such as the energy station and the neighbourhood garage with a mobile station as well as socio-cultural and educational facilities such as a kindergarten, youth club, neighbourhood meeting place and neighbourhood management.

  • Closed loop quarters. Between Frankfurt and Taunus

    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 neighborhoods will be car-free.

    The aim is to create circularly organized neighborhoods - neighborhoods 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.

  • Pelikan Mix⁴

    The project PELIKAN MIX4 is characterized by a variety of dwelling types according to urban lifestyles. Within an urban master plan four distinctive characteristics are developed:
    A landscape tableau is the connecting element, forming an entrée for the private, semi-public and public spaces. Generous lobbies in each house compose a discrete identity and a space of encounters. A great flexibility in the floor plans allows a variety of different apartments in size and type. According to society demands, the types "wellness", "sustainable", "extravagant" and "comfortable" are developed. They differ in constellation of rooms, material, building equipment and the offer of outdoor spaces. So called "Glorietten" crown the buildings and optimize light, spatial peculiarity and views.

  • Residential Crown Carpark Windmühlenstraße

    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 center is improved. The existing parking garage is complemented with penthouses as part of the renovation of 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.

  • Government district Peking

    Better Water - Better City!

    Together with Wasser Hannover and the Chinese Academy for Urban Planning and Design (CAUPD) we have won one of three initial competitions for the new seat of government of the Chinese capital Beijing. As part of the planned amalgamation of Beijing with the cities of Tianjin and Hebei, the new government district will emerge in Tongzhou. The landscape-planning-based competition entry includes the integration of a holistic water and open-space system. The new government district's unique design features and identity were created based on its ecological and technical needs.

    Through the merging of Beijing with the cities of Tianjin and Hebei, China's new megacity of Jing-Jin-Ji will emerge, with 130 million inhabitants. To relieve the Beijing city core, this project involves moving the government district from the historical city centre to Tongzhou. The competition entry comprised the planning of a 600-hectare open space to complement the existing urban development masterplan. The varied open spaces will be used for sport, culture, commerce, and education, whereby the identity of each space will be considerably shaped by the proposed water concept.

    The proposal for a holistic water system fits into and improves the existing urban-development masterplan, and also considerably helps shape the natural and urban environment that was decisive for winning first place. In keeping with the slogan 'better water – better city', the specially developed sponge-city measures from flood protection to rainwater management all the way to blue-green infrastructure are integrated into the city. The ecologically and technically necessary rainwater canals, for example, are generally not run underground, but instead staged as a special city landscape element and made into an ecologically valuable identifying feature of the services, retail and residential quarters. In this way, different subspaces can be developed and special programs and functions can be offered through water design that will characterize the liveliness and atmosphere of the future government district.

    The combination of innovative water-cleaning technologies with a resource-saving grey-water use concept makes for a convincing overall design. We developed the required technical water-treatment facilities into an attractive place with character.

  • At the old freight yard

    In cooperation with the Dutch landscape architects Felixx, we created a design for the site of the old freight yard in Duisburg.

    The site is being freed from its island location and reclaimed as a piece of the city: The large Westpark acts as a magnet for all Duisburg residents and brings life to the quarter. An important component is the almost 14 hectares of open space that is used for a better climate, cleaner air, water management, biodiversity as well as sport, recreation, and community. In particular, local public transport and non-motorized traffic will be strengthened: five bridges (bike/foot) span the motorway and tracks and connect the largely car-free district with its neighborhoods.

    open space
    The Westpark is designed as a spacious landscape park and, with a size of almost 14 hectares, offers space for all Duisburgers. A 12m high wall with a tree filter shields the noise and pollutants from the motorway. Different habitats and areas of use are created from north to south: meadow park, cultural park, sports park, water park, forest park. A central axis - the mile - links the quarter with the city in the north and the park in the south. In addition, all east-west connections are linked to the mile.

    program
    The mixed-used quarter offers space for around 4,000 residents and 2,500 jobs thanks to various building types. The quiet residential areas each face the garden courtyard. In the north, there is the innovation quarter with offices, co-working, fab lab, start-up center, co-living, hotel, etc. Around the quarter square in the north, there are local suppliers, shops, cafes, market hall and market. An educational center is being built on Karl-Lehr-Straße with the "Karl 1", a house for movement + culture, as well as a library, VHS, music school, and elementary school with a daycare center at Westpark.

    Water, climate, energy
    The rainwater management works according to sponge city and cascade principles, in which rainwater is retained, temporarily stored, evaporated, and seeped away. The measures improve the microclimate (e.g. evaporative cooling, air purification), increase biodiversity, and the quality of urban space (recreational areas). Technical and near-natural measures of rainwater management are combined: These include blue-green roofs, infiltratable coverings, or various urban wetlands, i.e. retention and evaporation areas and plant-based cleaning systems. The energy system is organized on a decentralized basis and includes a heating, cooling, and electricity network, each of which is connected to the urban network. Roofs and facades are used to generate electricity and heat (photovoltaics).
    The west park is used to air-condition the quarter: Warm winds from the southwest (main wind direction) are cooled and filtered in the west park and guided into the depths of the quarter via the open east-west paths.

    Love Parade Memorial
    The Love Parade memorial is to be integrated into the quarter. A place that has its place in people's everyday life. The memorial will be part of the planned park, a place of tranquility, and will also be located in the heart of the new quarter. There is also a memorial grove between the mile and the memorial.

    We are very happy about the strong voting results of the public vote and the high level of support and acceptance from the people of Duisburg.

  • Innovation Valley Garzweiler

    Due to the planned coal phase-out by 2038 and thus the elimination of a complete industry with many jobs, strong visions of the future already need to be developed today. How can we reintegrate the gigantic areas that will soon be fallow again in a sustainable manner and make them usable?

    Located in the border triangle, our workshop was about developing a vision for the area in and around Garzweiler. The main goal here was to move away from the current linear to a circular economy. The starting point of the concept was the question of how we can draw a strong vision of the place that addresses its complex issues: What does innovation need? What will energy production look like in the future? How can we restore the immensely damaged ecosystem and reconnect the fragmented biotope network? And what do the municipalities and residents of the region need? How can all these aspects be thought of in a cycle and thus map a strong, sustainable system?

    To give answers to all of these questions, the concept provides for the creation of an innovation network from three well-developed commercial locations in Jüchen, Jackerath, and Frimmersdorf, which tie in with existing plans. The conversion of the Frimmersdorf power plant, which is otherwise to be demolished (planned paralysis in 2021), creates a supra-regional innovation hub and acts as a gateway to the region. Its huge pre-built areas serve as a playground for start-ups as well as established companies. The power plant is a visual reminder of the cultural heritage and the important past of the region, but on the other hand, shows the big step forward towards a sustainable future. The pioneering spirit that has prevailed for decades is being rethought and translated into 2035.

    Large contiguous recultivation areas for industrial agriculture feed electricity into the local grid through additional use for wind power and PV systems. We are creating ecological corridors (forestry recultivated, natural green structures), which in the future will span between the lakeshore and the forests of the Erft floodplain and, in addition to safeguarding the species network, also represent interesting areas for tourism. Thus the economic situation of the region is strengthened. They are lined with laboratory areas: small-scale fields and garden structures on which circular agriculture is researched, tested, and applied.

    Garzweiler is an attractive area, but how can villages be developed, and what offers need to be created? Resource-saving, water management, or new forms of mobility are just a selection of important topics and factors that need to be considered. We propose different lighthouse regions in which to settle. In this way, for example, the new town of Niers am See is created. With the inevitable flooding of the Garzweiler II opencast mine and the resulting lake the size of the Tegernsee, there is an extraordinary opportunity for the realization of a model city with decentralized rainwater management and close networking in the adjacent natural biotopes. As soon as the opencast mining is completed, the respective villages can grow to the edge of the former mine and then have their own waterfront promenades in the final state.

    The concept is rounded off by a cableway that links the various areas.

  • Unusual living KIDS

    In Germany, 90% of all children live in cities - 60% in large and medium-sized cities alone.

    The concept study takes this as an opportunity to redesign the existing housing estate on Bürgermeister-Reuter-Straße in Bremen Vahr according to the principles of a child-friendly city. The settlement shows various potentials in open space as well as in the building stock. In addition to the location on Lake Vahr, the rich tree population and the generous open spaces, the sealed parking spaces, the repetitive, underused open spaces, and the missing center pose challenges.

    In phase 0, a footbridge will be built that connects the neighborhoods with each other and interweaves the settlement with the network of paths in the area. It creates a center for the entire quarter, creates an address on Kurt-Schumacher-Allee, invites you to the quarter, and leads to the water. This is where people play, romp, rest, chat, celebrate, cook - a meeting point and link between the neighborhoods.

    The redensification strategy is subordinate to the maintenance of the valuable tree population and is divided into measures of upgrading, increasing, and adding. New forms of living promote the social mix in the neighborhood and enable new, diverse family structures and forms of living together in the long term.

    A central neighborhood garage on the main street, supplemented with decentralized mobile stations, enables a car-free neighborhood - this increases security, which at the same time brings more space to play on the street.

    The open space is made usable in the form of private gardens, neighborhood islands, playgrounds, and the "children's wilderness". The footbridge offers various areas of play - also for informal play and nature experiences.

    In the climate-neutral quarter, the roofs are activated as blue-green solar roofs. The rainwater is collected, stored, and evaporated. Biodiversity is promoted and made visible through bee pastures, hedges, and orchards. The footbridge leads as a research path through the future-oriented quarter. There, children can play close to nature and explore relationships between themselves and their environment. Sustainable use of resources can be learned in childhood.
