The Klimaquartier Würselen is characterized by strong open space references and clearly defined urban spaces. It mediates between the new and existing settlement bodies, the various neighborhoods and the open landscape in the east. In order to meet the current climatic changes and the scarcity of resources, the neighborhood will be developed in a space- and material-saving manner using timber construction; water and other resources will be used locally and treated on site.

The new neighborhood landscape complements the existing open block perimeter while forming defined neighborhoods with intimate courtyards that combine village courtyard structures with play streets. The small-scale buildings surround the Green Center, which forms the heart of the neighborhood and functions as a meeting space for the surrounding neighborhoods.

All buildings are based on the same construction grid, which corresponds to the deep garage grid of 5m. The bulkhead construction method, optimized for timber construction, forms the basis for the feasibility of the various building typologies. At the same time, repetitive building elements and construction principles ensure efficient planning and minimized construction times. The efficient basic structure allows for a variety of floor plan types - from one-room apartments to row houses to group apartments.

The neighborhood at Fuhrenkamp takes on the responsibility of a climate-friendly settlement. The compact development minimizes the degree of sealing and creates generous green spaces with dense tree populations. These air-condition the neighborhood and increase biodiversity. Stormwater management functions according to a sponge city and cascade principles, in which rainwater is retained and temporarily stored, evaporates and infiltrates or is discharged into local ditches. Renewable energy is generated locally.

The use of durable materials, building with used and recycled materials, and a wood construction method contribute to climate protection. Promoting and enabling a change in mobility behavior achieves a low-car neighborhood. The climate quarter creates a social mix by offering diverse, also new forms of housing as well as friendly street spaces for play and circulation, diverse open spaces and neighborhood centers for all generations.

The Fuhrenkamp neighborhood is being developed in phases, beginning in the south and growing out of the city. The development in individual steps makes it possible to learn from what already exists and to make appropriate adjustments to meet changing needs. The edges of the individual neighborhoods in the area react in a differentiated manner to their context: the neighborhoods leave sufficient distance to the section of forest to the west. At the same time, the biotope network is strengthened and expanded in a vertical direction between the existing structures and the new neighborhoods to the east. The new district is holistically interconnected through a framework of neighborhood centers.

How to build using simple means in construction, building services, fire protection, floor plan design and open space and still react to the ongoing questions of climate adjustment and resiliency?

"Build Simply" shows answers to these questions in a 5-step strategy which we developed together with our cooperation partners on levels of structural engineering, building technology and landscape design:

1. Simple volumes connected to an active arcade
2. Intelligent fire protection
3. Reduction of technology through clever construction
4. Use of local energy resources
5. Cradle-to-cradle/Build sorted

On an architectural level, these principles are implemented by public and semi-public spaces aligned to the common yard, the lowest building class possible, continous floor plans for a better ventilation within each apartment and a structure allowing an effective planning with wood. Nevertheless, the main focus of the design relies on the needs of people to promote a
communal and sustainable togetherness

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.

The Humboldt Block combines existing and new buildings to create a new productive quarter with a character know for Berlin, connects on many levels with its surrounding and can respond flexible on future challenges. The urban design aims to connect the area wit its surrounding - on one side the Humboldthain as an important open space, on the other side with the adjacent areas and institutions of the technology park.

The structural setting completes the perimeter development of the building block along Gustav-Meyer-Allee. Existing and new buildings merge to form a quarter with a strong character, creating an outside view typical for the location. The part on Gustav-Meyer-Allee with its public first floor areas form the showcase, representing the new quarter. In the center of the Humboldt Block, a sequence of squares is created to connect the entrances of the new and old buildings. Those buildings face each other and form a common public space.

The development is divided into nine north-south oriented strips of buildings, some of which are grouped together by internal courtyards. The main internal development for delivery traffic divides the resulting building strips in an east-west direction. The permeable building structure opens generously to the Humboldthain and links the quarter with its surroundings. The main thoroughfare is aligned with the two existing crosswalks of the block.

The design for the JAWA forms an identity-creating neighbourhood that does justice to the self-imposed goals of socially and ecologically sustainable urban development. In terms of urban development and design, the ensemble fits into the Wasserstadt Limmer and, at the same time, enables a wide range of individual living and community wishes.

The ensemble is open to the public, can be used in a variety of ways and is therefore lively due to an "open space shelf" with small and large balconies, loggias, planters, etc. Individual living requirements from small apartments with and without a patio to terraced houses or spacious family apartments come together as a clear volume and are characterized by a uniform design.

The communal inner courtyard will be greened naturally. At its heart, there are a variety of community offerings: a large courtyard terrace for parties and events, an area for urban gardening with a barbecue area and a long table for eating together. There is also a spacious play area in the northern part of the courtyard. Sustainable construction protects the resources of future generations. Both the passive house standard and the Schottenbau grid optimized for timber construction contribute to this. In addition, the compact construction volume minimizes energy consumption.

The maximum utilization of the possible construction volume guarantees an economical undertaking and reduces the community costs to be allocated. As a result, more apartments are created for people who can participate and contribute to the JAWA building community.

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.

With the new building respectively renovation, IGS (Integrated Comprehensive School) Langenhagen is changing from a school location with many buildings and addresses, separate uses and not barrier-free routes to an inclusive landscape of shared learning in close contact with the city and nature. Learning clusters with classrooms, differentiation areas and mixed-use recreation areas are organized around a central common centre and thus offer a variety of places to learn, linger, communicate and relax.

The new school building is located at an urban node. While the south is characterized by loose and urban development and large-scale centre functions, the north is a green recreational area with old trees, green meadows and biotopes close to the water. The new structure mediates between these two worlds and creates a clear, urban address in the south as well as a central schoolyard in the north, which turns into a landscape park.

Together with the existing cafeteria, the school building takes up a clear and public space. This is the place to arrive and linger for students, teachers and visitors. Supported by the large terrace of the cafeteria, this creates a lively space. The square is in close spatial connection with the newly designed bus stop, the bicycle parking spaces and the town hall square on the opposite side of the street. In the north, the structure interlocks carefully with the school park. Between the new building and the refurbished creative pavilion, there is a lively, enclosed, green break room, which connects the existing buildings (sports halls and creative pavilion) in an east-west direction. The compact building cubature maximizes the preservation of the existing trees and minimizes surface sealing.

The building is designed as a wood-concrete hybrid construction. Optimal sun and glare protection while maximizing the use of daylight is guaranteed by blinds that align automatically depending on the amount of sunlight.

striking gate + green neighbourhood

The area at the Waldwiesenkreisel forms an important, previously misused entrance to Kiel city centre. With the development of the property, there is now a great opportunity to formulate a distinctive entrance to the city and to create urgently needed, high-quality living and working space.

By shielding the street noise, a quiet, green residential area is created inside the building complex, which brings the lush, northern open space into the quarter through its open design. This creates a green gem with its own identity in a heterogeneous urban environment.

The structural composition and the landscape-architectural interventions of the mixed-used "Kieler Knick" create a concise design language. The courtyard and the roof terraces are open-space extensions of the building and form an urban meeting point for workers, residents and visitors. Based on the diverse spatial program, places of encounter and exchange are created, as well as space for retreat and peace. The interplay of the dense trees and green roofs creates a particularly pleasant climatic situation in the quarter. In dialogue with the different types of living, a wide range of open spaces is created for shared and private use.

Additionally, Mobility is entirely geared towards the environmental network. Pedestrian and bicycle traffic are prioritized with different concepts. All necessary parking spaces for the MIT (tenants and visitors) are organized in the two separate underground garages. There are charging stations for e-vehicles as well as possible car-sharing offers in the direct vicinity of the development cores.

The colourful life!

In the middle of the Vierzig549 quarter, the "heart" of the entire area is being created, a lively meeting place with a high quality of stay and programmatic diversity; the pacesetter for "The colourful life". The different building types „high-rise" (wooden hybrid), „courtyard house", and point house are designed as a coherent ensemble. The mix of commercial and residential uses promotes the urban character of the area. In particular, the programming of the ground floors, which ranges from commercial to Live+Work to mezzanine living, contributes to this. However, with the exception of the ground floors, the buildings are used for either residential or commercial purposes to allow clear and easy circulation.

The green "urban grove" with park character and the multifunctional "square" complete the building structure. With their different atmospheres, they create a spatial and qualitative diversity in the quarter. Rainwater management is based on natural circulatory systems. Intensive green roofs (and extensive under the PV systems) delay runoff and encourage evaporation. An improvement in the local microclimate is expected through the systematic use and infiltration of rainwater in the open space. The inner area is car-free.

The design of the building is guided by the image of urban architecture with echoes of the history of the area. The façade grid is robust and reminiscent of industrial building types. It is used as a base layer for all buildings and thus combines the different types of high-rise building, courtyard building, and point building as an ensemble. At the same time, the grid allows flexible filling depending on use and orientation as well as individualization for recognition value. The structural concept consistently relies on recyclable building materials and sustainable construction with wood.

Grounded on rich Albanian heritage.

Aquarium Bay Hotel is designed based on the concept of sustainable tourism. The hotel comprises four separate pavilions, offering different experiences to their guests. Each pavilion has a distinct architectural language and shelters an inner courtyard with a specific and unique character. The four buildings contrast with their surroundings, as a way to accentuate and respect the outstanding local landscape. This landscape of rolling seaside hilltops covered in Mediterranean scrub, as well as the remote location, are considered two of the strongest, unique ‚assets' of the hotel.

The approach to the hotel - by car, boat and helicopter but also by foot and bicycle – is carefully orchestrated, as it forms the start of the customers' journey. Internal circulation is organized by a series of footpaths, - a seaside path, a forest path and a main ‚barefoot' path - making for a sensory experience. The central lobby pavilion provides direct access to the spa, restaurants, conference rooms and casino. Additionally, atmospheric facilities like the plunge pool, the bonfire area, the botanical garden and the rock pool add to the guest experience. The most remote volume houses a small restaurant and bar that allows this building to be operated independent from the others, thus maximizing the privacy of its guests.

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.

Bamako is in a phase of rapid urban development, with the population growing expansively; telecommunications are an integral part of this growth and are a marker for upward social mobility. The height, visibility, and clean volume of the new Orange Mali Headquarters express this situation, thus creating a landmark for the new, mobile urban class.

At the same time, the building sets the bar for offices and urban planning in Bamako, by creating a zero-energy building that incorporates greenery and improves the working environment of the Orange employees. The new Orange HQ is surrounded by a public garden, a layout that makes the office building more accessible and simultaneously creates a social space for gatherings and events. The green spaces continue into the interior of the new office building as a sequence of open terraces. By using 'stacked' office floors, and by interspacing these with high-quality open spaces, employees feel more connected and floorplans can be optimized.

The iconic, geometrical 'zig-zag' exterior is the result of a smart and site-specific design, avoiding direct sunlight on the facade.

Building on existing structures.

The plot of Bar Center in Fier (Albania), located next to our projects Rinia Complex and Building Block on a central urban intersection and adjacent to an inner-city park, was occupied by an existing building from the late 1990s. This building – the plinth of an unfinished high-rise, which stood at three storeys high – was unassuming and unfitting for this prominent location; therefore, the owners approached us to extend the building and upgrade the existing floors. So we used the volume of the existing building as a starting point for the design.

The addition activates the upper floors and makes them directly accessible from the new main square of Fier, to which the building now prominently orientates. The result is a stepped five-storey volume enclosed in a geometrical, rasterized façade. This geometrical façade, in turn, is partially clad in semi-transparent golden shading sheets, which function as a screen against the sunlight. Additionally, they bring more unity to the building's appearance. The volume, whose two newly added floors contain a publicly accessible rooftop bar with views over Fier, offers an urban topography that serves the city as a whole.

A very special project in our portfolio is the Chalimbana Local Government (CLG) Training Institute in Chalimbana, Zambia as it can be seen as a good example of a passive and self-sufficient city. The aim of the masterplan was to increase the quality of life of both students and academic staff of the Institute, to structure the campus for the long term, and to provide the grounds with a clear, recognizable identity.

Low-tech in construction but high-tech in designing, we created a plan that included everything needed for an autarchic project. In a very sustainable manner, we used the excavated soil to press it into bricks contributing to the buildings being passively cooled and heated. To achieve that we mainly used the sun energy. From a special angle and material of the roofs to the orientation of all buildings to strictly East-West, with the main facades (North & South) avoiding the low angles of the sun, CLG Training Institute became an eco-friendly vision made into reality. Also, we made sure that the rainwater and the cleaned sewage can drain into the groundwater locally, granting a precise water cycle.

The existing road provides access to the campus by car. Simultaneously, a new main route for pedestrian connections is established as the new 'heart' of the campus. It runs between the mostly residential area on the North and the educational program on the South side of the grounds. These two clusters - housing and education - at the two opposite ends of the campus are surrounded by the lecturers' houses, and by leisure activities. By closing off some of the student housing blocks, small neighbourhoods are created, with inner gardens and courtyards providing atmospheric living quarters.

The residential complex AnA is situated close to the Student Village of Tirana University on a magnificent hillside. The oddly-shaped site starts with a narrow edge along the street and widens sloping down 15 meters of level difference. The building folds as a continuous figure, respecting all the necessary distances to the property line and on itself. This stepped form creates a local landmark with an identifiable skyline in a very heterogeneous context.

The site opens itself to allow a pedestrian connection between the student village and the northern areas. This passage enlivens the commercial ground floor and the compound piazettas. The cuts in building volume are a response to the urban regulations and a way to break down the overall massing into pieces more related to the human scale. The same 'cut' approach is used in order to provide light and natural ventilation for circulation spaces. The attic floor has setbacks in strategic locations of the building for best views from the terraces for the exquisite apartments. The materialization aims for an elegant appearance with differentiated materials and patterns but an overall clean white look: the plinth is of fair-faced concrete with a diamond-shaped relief, the body from white plaster, crowned by an attic floor clad in beveled tiles for a shimmering reflection of the strong Albanian sun.

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.

When designing the Durres Beach Hotel in Golem, Albania, CITYFÖRSTER faced the challenge of creating quality within an unpromising context. Golem, a popular beach resort, enjoys a prime location on the sea and is set in a mountainous landscape. However, the village has suffered from uncontrolled development, resulting in a sprawling blanket of buildings. The site for the new hotel is located in the third row from the beach and faces a highway on the other side.

On the other hand, the site boasts a beautiful forest of mature Mediterranean pine trees and forms an anchor to a potential urban plaza in the south. In order to overcome the challenges, we designed a building rooted in the Modernist tradition, a compact building-block surrounded by greenery. This layout provides the entire building with light, air and space, and secludes the rooms on lower floors from their direct surroundings. An elevated roof garden compensates for the footprint and adds to the overall quality of the new hotel.

All rooms have highly finished interiors, as well as balconies offering different views – either towards the sea, towards the mountains, or towards the trees. Each balcony is cladded in natural stone from different regions in Albania, which creates a distinct rhythm in the façade. The west façade corresponds to the adjacent buildings, whilst the east façade follows the patterns of trees. The end result is a positive eyecatcher, clearly visible from the highway and the sea.

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.

A new primary and comprehensive school (IUS) is planned for the former site of the Helios AG in Cologne Ehrenfeld. The school concept is based on the idea of a "university school", which spatially implements the educational objectives of inclusiveness: The school comprises the grades 1 to 13 and operates closely with the teacher training of the University of Cologne. This is architecturally reflected in an open learning environment for all grades. As part of a new high-quality and dense city block, the school should be an integral part and actor of the district: The school premises may be used publicly and the school offers a range of activities to the neighborhood.
The school is designed as a compact structure, which is confidently positioned due to its clear-cut cubic form and at the same time contextualized by its orientation to axes and edges of the surroundings. It creates a clear address to the Vogelsanger Straße by a glass-enclosed foyer and a funnel-shaped, covered entrance situation. The inviting foyer and the localization of semi-public functions on the ground floor – such as the auditorium and educational center, the canteen, workshop and studio spaces – creates the desired integration of the school into the district and allows for important synergies of different usages.
The common center - "the heart of the school" - spans over two floors and offers spacious stairs for meeting and seating: A great place for communication and leisure for all functional areas of the whole school.

Excerpt from the jury report: "The jury praised in particular the optimal implementation of the educational objectives, which corresponds in a particular way to the intentions of the users. The learning environments are well designed and can be effectively used. Primary education is accessible as a separate unit on the first floor over short distances. The secondary education units I and II are localized on one level and are equipped with a spacious central communication zone, which provides space for a diverse range of activities. ..."

This urban design aims to create an attractive living environment for young families and couples and to give a new impulse to a large social housing estate from the 1960s. The existing open block structure will be maintained but is transformed into a structure with semi-private courtyards.

Different typologies - i.e. houses with ground-level access, apartments with open floor plans - add variation to the housing supply. Within the building blocks, elevated courtyards create a safe environment for social interaction between inhabitants, especially young families. Notwithstanding their open character, these courtyards offer a clear visual and functional border between public and private spaces.

Between the blocks, a sequence of car-free squares that draw on the surrounding structure contributes to a lively public space. To keep spaces as car-free as possible, most of the parking is organized in underground garages which are accessible from the edges of the block. By drawing on the existing structure, and by continuing the green belts and the existing rows of trees, the design creates a strong link with its surroundings.

The guiding principles in the design for the landmark building accommodating the West African Science Center, are developed from the site and its conditions as well as from vernacular forms of spatial organization and construction of Burkina Faso. The building itself is reflecting the idea of scientific research as it serves as a hub, connecting the centre and its partners with each other, with visitors as well as with the city of Ouaga¬dougu.

The heart of the building is the three-storey science area, containing all offices and their serving spaces. The ground floor connects all functions both spatially as well as programmatically through long visual axes. Inspired by traditional houses and settlements, the round shape of the building is effectively avoiding the low-standing sun as it slowly travels around the building. The climate concept focuses on natural ventilation in combination with night cooling and air movement by ceiling fans and solar chimneys and is in this way a best practice example for climate-adapted construction and sustainability.

The Dhermi Plaza Hotel has been designed as a 5-star hotel along Dhermi's promenade. The project optimizes the square meters available within the plot whilst merging with the context, and offers publically accessible facilities.

Its elongated volume is situated ideally between the beach to the south and the mountains to the north and is characterized by a dynamic facade. The shading system, composed of double-facing sliding shutters, plays with the shadows created by the thin walls. This creates a sense of movement, and reveals the life inside the building, making the hotel guests the 'accomplices' of the architecture.

The hotel hosts different functions which can be separated if necessary, such as the restaurant, spa, and beauty salon on the -1 floor level;5 shops, a pool bar, a swimming pool, a bar, and the hotel lobby on the ground floor level; and an array of variously sized rooms on the first, second and third floor. The top floor has been designed as an active neighborhood/village, with various leisure facilities for both adults and children. It stands out from the rhythm of the facade and offers the guests panoramic views The hotel grounds have been designed so as to offer a range of different sports activities, from swimming in the 25 m pool to playing basketball on the shaded field.

Lagodekhi Protected Areas (LPA) in the extreme north-eastern part of Georgia at the southern slopes of the Caucasus and with altitudes from 590 to 3500 m, is one of the world's best-preserved areas with diversity of natural landscapes. The project of developing a TreeTop Trail as a new touristic product is to attract more visitors and, considering the transboundary potential of the LPA, make it one of the most attractive destinations, to be included in future transboundary ecotourism products.

The concept emphasizes the forest as the protagonist and proposes a minimalistic design, a circular shaped trail that gradually ascends towads the tree canopies. Additional program is added in order to enhance the experience of forest. This includes a watch tower, a dome, a large net, a cave, and multiple platforms.

How to organize attractive family living and low energy housing in a high-density city center?

Our award-winning design for the Embassy Residences in Albania provides high-quality, family-friendly, and low-energy housing units in the city center of Tirana, one of the fastest-growing cities in Europe.

The project responds to the mayor's ambition to limit the growth of the city and to counter sub-urban developments with a more diverse range of housing typologies. On top of a commercial plinth and two parking levels rises a series of stacked villas, connected by a semi-public stair. This serves as alternative circulation and additional, shared informal outside space to the apartments. 



The floorplans protect the privacy of the apartments but allow residents to sit on their porch or use the staircase to access their apartment when in the mood for a chat or a Friday afternoon drink. Research has led to a compact build-up of irrigated substrate layers that can support rich vegetation on the stair, balconies, and roof terraces.

The facade consists of two layers arranged according to insolation. A basic glass layer is protected by a secondary shading layer of anodized aluminum where it is not protected by surrounding buildings or cantilevering volumes. This results in high transparency on the one and low energy costs on the other hand in addition to preventing the building from the hot Mediterranean sun whilst still guaranteeing an elegant look.

The urban concept is based on a compact building envelope positioned on the plot, creating multifarious open public spaces for various outdoor use. The compact volume is achieved by stacking the program: The space-centred gym is located on the first floor, the community centre with its open, active and animating facades is based on ground level. Emerging from its program, the building volume is shaped with several recesses and kerfs.

The entrances to the different functions are visualized by cut-outs of the volume. The building attains efficiency by layering functions and multiple-shift usage. The structure consists of a mix of reinforced concrete on the base and prefabricated cross-laminated timber on the upper storey. On the ground level, the facades are designed with large glazing elements and fibre-cement coated with colourful patterns. The facades of the gym are clad with black, large scale trapezoidal sheetings. Translucent façade areas from polycarbonate panels stretch around the upper corners, in order to give further differentiation to the building volume and embed it in the surrounding scale.

social, cosy, flexible
living circularly in de Waalsprong

For the Waalsprong quarter in Nijmegen, CITYFÖRSTER created a design for 70 social rental homes. The skyrocketing housing shortage is linked directly to the climate crisis and biodiversity loss. Seeing the potential of new social housing, we focused on high density, flexibility and low-tech design solutions to propose a circular construction.

A large main volume adjacent to a large sports hall is combined with smaller building volumes facing the park: An exciting combination with a high density of housing that still retains the community feeling of a small-scale, cosy neighbourhood.

The various buildings, terraces, squares and apartments are connected by a network of stairs and bridges with a central lift core in the main volume, which invites you to explore, exchange and interact.

The main volume and the smaller buildings are built from the same modular wooden elements, allowing the constructions to be disassembled and reused at the end of their lifespan. The floor plan of all apartments can be arranged flexibly. The units can be joined together so that the new development can easily adapt to changing housing demands without high costs or complicated interventions.

Low-tech design solutions such as an awning, conservatories and solar chimneys ensure low energy consumption and reduce material use. Other installations are set up as demountable modules to round off the circularity concept.

Cityförster designed a school for the charity project of the King Bansah Ghana development association. Below an approx. 75m long roof several volumes will be constructed in a simple way representing a unique identity. The roof itself is split in two vertical shifted parts to provide natural ventilation for the air and light-permeable volumes. The air cools down beneath the canopies and circulates through the pattern openings of the concrete building blocks into the workshops. Once heated up the hot air exhaust through the rooftop vents.

The roof is also used to mount numerous photovoltaic modules that provide the necessary self-sufficient power supply. The construction process will be split into three stages. After each stage, the completed buildings can be used immediately. In the first stage, the artisan workshops will be built. As a second stage, the workshops for wood and metalworking and the staff room will be constructed. Finally, the car repair shop and the covered forecourt will be added to the entire construction. The illumination and air ventilation are provided through customized brickwork. The openings in the concrete moulded bricks refer to patterns of traditional fabrics in Ghana. The lower wall segments are closed for dirt protection and they offer the opportunity for the sign paint shop to use their skills and write all donators names on the facade of the building.

The program of the new quarter entrance describes a modern mixed-used block in which different functions come together and are arranged compactly to each other. The entrances to the main functions are oriented towards the public spaces and emphasise the priority square and corner situations in the urban context. The 7-storey residential tower houses 60 micro apartments with a café on the ground floor along the entire facade. The eastern block houses is the assisted living, the western block is the care facility, including the supermarket with parking decks and a southern and northern row of shops. All ground floor facades with public uses open up to the public space with generously sized windows. The design envisages a solid construction method in reinforced concrete and brickwork, which optimally depicts the various building parts, functions and room sizes according to their requirements.

The city block is structured by two cuts towards the public street. In this way, a community courtyard with neighboring pathways is created. The perimeter block development consists of six residential units and twelve townhouses on the east side. The street-facing brick facades are representative and respond to the importance of the entrance to the quarter. The spacious inner courtyard is zoned into a communal green center, surrounding paths and the private gardens lining the first floor apartments. All building entrances are barrier-free and all apartments are planned to be barrier-free. Each apartment has an outdoor sitting area and a small storage room. The underground parking garage is located in an L-shape under the northern block and is accessible from all staircases of the apartment buildings. There are also 145 bicycle parking spaces, some of which are equipped with charging stations.

In the 14-month planning and realisation stage, a baroque hunting castle in Seesen was redeveloped with a focus on simplicity and clarity at a reasonable price. Also, the permanent exhibition of the museum was conceived and moved.

Central attention at the rebuilding work was the restoration of spatial relations and structures, as well as the creation of a high-quality, modern but timeless showroom, which is able to take on the various exhibits, including specialities such as 'The world's longest piano string. The exhibition has a modern pedagogical approach and offers attractions and information for all age groups. Additionally, the value was placed to increase children's participation through experimental- and multimedia stations. In this way the museum can be accessed by a variety of senses, understanding through seeing, hearing and touching.

The existing U-Hall is the heart of the BUGA. A green ring floats above it as a landmark visible from afar.
It is a living sculpture that stands for sustainable recycling management, the willingness to experiment and a spirit of optimism.

This circularly conceived tree hall, brought into the vertical, is not only part of the exhibition, but also a break in the tour and a place for the best views over the entire site. The tree house, built from recycled building materials, provides a habitat for flora and fauna, exhibition opportunities for field research and allows views of the solar power plant on the U-hall. Thus the ring is the central location of the U-Hall. This is where the tours and guided tours start, where people meet and where smaller and larger events take place.

The draft envisages an extension of the Lutherschule through a powerful and independent structure, which fits into the existing block structure and self-confidently positions itself to the Engelbosteler Damm.
The five-storey building forms in a modern and contemporary architectural language a clearly perceptible address while radiating openness and transparency. At the same time, the indented ground floor facade with its striking brick arches creates a spacious and covered entrance area.

The central organizational idea is the clustering and self-evident stacking of the different areas of use:
The communal areas are located on the ground floor, the creative areas on the 1st floor, the natural sciences on the 2nd floor and the grade clusters on the two upper floors. As in the floors below, the classrooms are grouped around a central communication zone that creates additional learning venues with niches and open areas.

The new residential neighbourhood Hilligenwöhren is located on the threshold of a compact city to open landscape in Bothfeld. A composition of three- to four-storey buildings generates two courtyards with different spatial qualities. The norther green courtyards are the new neighbourhood's intimate centre, whereas the southern courtyard opens up to the street and hence to the neighbourhood.

The buildings are connected via access balconies which activate the courtyards and are the basis for a vivid community. The central community room for all residents connects the two green spaces. It is the neighbourhood's living room. By opening and widening spaces, informal meeting points and social contact surfaces are offered. The building structure enables a flexible arrangement of various residential typologies und therefore a social mixture.

A solid structure for the development of a long-lasting neighbourhood is offered. Furthermore, natural building materials ensure comfortable and healthy living environments.

The Nümbrecht School Centre is to be restructured in several construction phases and thus converted from a classical corridor school with internal, anonymous and unused corridors into a new spatial-pedagogical concept, the Cluster School.
The corridors will be activated and transformed into communication zones, supplemented by group / EVA rooms and team stations, as well as niches and self-study areas, and opened to the communication zone.

In order to maintain a clear location of the gymnasium and the secondary school after the merging of the Hauptschule and Realschule to form the secondary school, the former Hauptschule will be demolished and the school centre supplemented by the new building of the secondary school. The planned new building contains 18 classes, 3 team rooms and 12 special learning rooms, which are grouped together in clusters.
The central interface between the existing building and the new one is the "common centre", which ensures the connection of the new building to the existing school centre.

Upside Down, Downside Up!

For the 8th sculpture Symposium (2017), Korça Municipality invited a selected group of architects, together with sculptors, to create temporary pavilions triggering the revitalisation of public spaces.

By inverting an abstract tree, Shu-Wei Chang, the sculptor, worked with the concept of 'roots-seeking'. The branches now grow towards the underground, recollecting the past, possibly finding some sort of lost identity. The proposition of this pavilion plays with this concept. A mirror that "returns" the sculpture to the "natural position" resulting in the viewer being inverted in relation to the surroundings. The structure, a form of a house, is stripped to its fundamentals. The materials choice (lumber and scrap wood) was intended to create a sustainable low-cost proposition while withstanding the time and made use of the limited availability of materials locally. Exploring further the 'back to the roots' concept, a traditional hanged Albanian carpet became the "soil" in which the tree seeks aliment. The pans (used to cook Korça typical meatballs) were positioned like flowers on a prairie. In conclusion, we aim to provoke a reflection of traditions as our identity ground in contemporary life.

The design for the landmark building of 5.500sqm, housing the New Lands Commission, will be a symbol of the new spirit of transparency and efficiency, bringing together the currently dispersed Land Sector Agencies. The building has an important symbolic impact due to the recent nationwide establishment of the land registry and is to represent a new All-Ghanaian identity. The design responds to local climatic and social parameters throughout all scales.

All design elements, from the urban setting out to the building's shape and its materialization aim towards natural and sustainable performance, fulfilling several functions at the same time. The circulation system forms the core of the building, spiralling upwards between two rings of offices on different levels. By breaking the clear separation between floors this system provides a continuous movement, bringing the NLC together on one continuous floor, with a variety of perspectives in and throughout the building. The parametric design of the outer appearance of the building guarantees functional performance whilst allowing for aesthetic variation. The diamond-shaped bamboo panels all follow the lowest sun-angle providing shade and filtered natural light at the same time.

"... In the front the Baltic Sea, in the back the Friedrichstraße ..." In the EuroCity Berlin one can come close to this ideal. The design combines an urban block typology with a distinctively shaped bar - " the Wolkenbügel". Its shape is characterized by a large void. This wide passage connects the block via the neighbourhood square with the waterfront and at the same time the waterfront with the city.

The void forms a partially covered urban stage for public uses such as weekly market, game or sport and thus a lively place along the promenade. The block is orientated to a central courtyard, which is connected to the neighbourhood square. The block is divided into ten different houses whose building height of seven floors decreases stepwise to five. All roofs are used as terraces. According to the different housing typologies and sizes, the widths of the houses vary as well. The houses are also distinguished in terms of facade rhythm and materiality.

A listed villa of the 1850ties was converted into two family apartments. The large garden is used collectively. The 1st and 2nd floors were redesigned in relation to the needs of a couple with five children. Spaces „suitable for everyday use" are created and at the same time, the special character of the historic building with its ornamental elements and valuable wooden floors is strengthened.

To reestablish the former spaciousness a multitude of fixtures and walls were demolished. The roof was reconstructed according to current energetic standards. The first floor serves as an entrance area with a large hall leading to the kitchen and the balcony. The master bedroom and one kid's room are orientated to the garden. The former ballroom as the heart of the building is used as a dining and living room. The space has an impressive size (55m2, 6m high) and is decorated with an ornamental ceiling that was preserved and - where necessary - restored. A gallery is installed into the ballroom as a slender glass-steel-structure: The stairs are suspended from the gallery to keep the parquetry untouched. The second floor is reserved „for kids only" and features four rooms, a play hall, and a bathroom. The staircase between the two floors is enhanced in its spaciousness by opening up a part of the ceiling. All design and constructive measurements were undertaken in detailed consultation with the institution for historic preservation.

The Martin Luther School is an upper secondary school with a special focus on musical education. It houses about 1600 pupils. The extension of the existing building became necessary to adapt to contemporary didactic concepts and to allow for all-day care. It contains classrooms, a natural science block, music rooms, a canteen and a gymnasium.

The design translates the demands concerning resource efficiency and preservation in a sensual and sensible manner. The main climatic feature of the building is the shape of the building itself: So-called solar chimneys foster natural ventilation by stack effect and become a significant formal element. The expressive roofscape also em­phasizes places inside the building – large roof lights extend the space upwards and provide particular light. During school hours these areas are open spaces to be appropriated by different age groups for independent learning. The building is conceived as a timber frame structure with a larch-wood cladding.

At the Hettlicher Masch, the new heart of the Meyer&Meyer company site is to be built. The office building is designed to be open, inviting and present as a "forum". The design is naturally integrated into the height development of the surroundings, forms a striking and inviting address to the street, but is also present and visible to the highway due to its three-storey structure.

The rooms of the office building are organised around a two-storey gallery room and offer flexible work and learning rooms as well as a large variety of programmes with a café, showroom and fitness area. The ground floor in particular is characterised by its floor plan flexibility, as the atrium can be extended for company parties or large congresses. In addition, spacious terraces and loggias form encounter zones and recreation areas. A photovoltaic system, extensive roof greening and an intelligent self-sufficiency concept make this design in wood-reinforced concrete hybrid-construction fit for the future. Thus this design is also a prototype of new working worlds, which are characterised by atmosphere, diverse meeting spaces and flexibility of use.

The Rinia Complex is located in a former youth park in the center of Fier, on a plot that is open to 3 sides, facing different contexts. Our design for the mixed-use complex addresses these contexts, which represent the different and differing needs of the area. The building seeks to express the ambitions of the City of Fier, that is: to create a new image, one that is fitting for a city that is dynamic and continually growing, and to add important functions to the city like a public 25m pool and a cinema.

Rinia Complex is a truly multifunctional building, with a program that also includes a 5-star hotel, 2 floors of parking space, residential units, a bank, a shopping center, a restaurant, and a casino. All public functions of the complex are accessible directly from the street via external staircases and are embedded into their urban surroundings. The building has been designed to be used in different ways at different moments throughout the day, offering both public/open access and private/restricted access areas. The intricate program has been fitted into a single volume, a uniquely shaped building that is internally 'fragmented' in order to give an answer to the different needs and the diversity of the context, but which also retains its flexibility as an urban 'shelf' that can take on a variety of functions.

The Rubber House as a price winning project in the Eenvoud/ Simplicity competition was selected to be built in Almere, Netherlands, as one of 12 experimental housing projects. In volume and style inspired by the simple and archetypal Dutch barn architecture the Rubberhouse forms a simple asymmetric double pitched roof inhabiting 2 storeys, in combination with a single pitch roof with one storey. The resource saving construction consists of massive wood panels from cross-laminated timber. The outer walls and the roof surface are clad with black EPDM foil. In contrast to that the atmosphere of the inside is characterized by the natural warm surface of the massive wooden walls. The utilization concept proposes small private rooms in favour of a generous open plan living area. Clear lines of sight through the entire building support the robust, open space sequence and allow visual connections into the adjacent forest. The living room can be expanded via the large sliding glass doors onto the terrace. The high degree of prefabrication allowed for a building period of only three months.

Our reconstruction concept of Tirana's "Student City 2" aims to show the great potential for particularly thermal energy savings in construction, modern student housing and is showcasing a well performing example how public and private sector can interact. As the buildings suffers from massive deterioration on the inside, main focus of the energy concept lays on a replacement of all basic infrastructure, including a adequate ventilation and heating systems as well as new windows as its centrepiece to remedy humidity. Different subdivisions of student rooms with joined shared bathrooms and modifications in use of common rooms allows spacious privacy and reacts on students needs. Applying a complementary colored orientation and material system for each dormitory allows visual indication of buildings, floors and rooms and provides "Student City 2" with a unique identity. As the roofs of the buildings offer common space, they can be used according to public or economic visions of its users and leverage "Student City 2" to be Albania's pilot energy efficiency project.

The design concept 'Green Wave' generates a holistic image and a characteristic coastal skyline for the site of Kirkjusandur in Reykjavik, Iceland. Two design principles characterize the appearance of all buildings: The dynamic shape of the wave as an aesthetic concept and the integration of green spaces as vital elements of functional and atmospheric quality. The new headquarters of Glitnir Bank, a nine-storey building addressing the prominent highway Sæbraut, will be the key figure for the future development.

The elevated entrance plaza is secluded from the public flow on ground level and sheltered from heavy winds coming from the shore. Open working spaces can be organised and subdivided flexibly. Winter gardens on each floor increase internal lighting, provide space for informal communication and create a comfortable atmosphere and climate. A decentralized ventilation system and a heating system based on geothermal energy are implemented, which are economical in maintenance, space-saving and highly energy efficient. The façade consists of tilted glass elements creating a "deep skin" that reflects natural and artificial light in different angles.

House 1 is the first built project of the masterplan 'mirror twins'. On top of a shared commercial ground floor a green link connects the site with the close-by park. The two seperate buildings connected by the common plinth are generating an enormous amount of requested square meters. Rather massive volumes are perforated by a series of programmatic voids that connect to a common circulation space, an inner void. The much needed public space is integrated into the building by creating a second entry level and reinterpreting the circulation space. The engraving appearance
of House 1 refers to the typical salient facades of Tirana. Multiple tilted strips create a rich play of light and shadow.
