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.

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.

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.

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.

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.

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 development of Buchholzer Grün creates a residential area in an attractive location. The five-storey and the four-storey apartment buildings in combination with ten three-storey townhouses form the northern opening of the new quatier. The three new buildings develop a powerful, own identity, which incorporate the urban connection to the surrounding city districts and the neighbouring Podbielskistraße. The rhythmization in the height development as well as the verticality through the overlapping windows and balconies in the clinker facade are central design principles. The change of material makes the entrance areas clearly recognizable and at the same time they fit into the overall structure of the facades. The result is a robust, unpretentious and solid figure. The multi-storey housing units impress with an exciting mix of tenements and condominiums in different sizes, while the townhouses offer a small type of building as well as a large one and enable parking inside the house.

The Henschel Quarter opens up hertitage sites to the public and secures them through flexible use. It is integrated into the city and is accessible to everyone. The aim is to preserve the historic industrial culture and make it usable. Listed buildings are carefully restored and remain part of the public space. The industrial past will be preserved through minimally invasive interventions, while new and predominantly commercial uses will revitalize the old halls. The open space will be transformed, historical traces such as tracks and crane runways will be preserved, supplemented by green spaces and playgrounds. In terms of urban planning, small-scale building typologies create the transition to adjacent districts, while high points mark important locations. Connections for pedestrians and cyclists create a continuous and close-knit network in the district. The existing buildings will be supplemented by new buildings whose design is based on the industrial character. Historic parts of the buildings will be retained and partially integrated into the outdoor space. In the center of the quarter, a "hall for all" with restaurants, culture and sports will be created, surrounded by creative and commercial uses.

The Henschel Quarter focuses on sustainability by preserving the existing buildings and reusing gray energy. Demolition materials are recycled on site and new buildings are constructed from sustainable materials. Renewable energies such as solar panels and geothermal energy supply the quarter, while open spaces improve the microclimate, and the combination of history, commercial, cultural and innovative offerings makes the Henschel Quarter a vibrant part of Kassel.

Urban development
The Change Factory combines flexible uses and high-quality open spaces along the river Inde and Indestraße. A four-storey high building with a roof terrace marks the main entrance and lends urban presence. The three staggered building volumes form a work yard to the north and terraces to the south for working and relaxing on the Inde. To the north, the buildings are stepped down towards the cemetery. To the east is a space-efficient mobility hub, which is directly connected to the main entrance via the internal Innovation Mile.

Open space
The Change Factory forms an identity-forming backbone of the public space along the Inde. A spacious forecourt with dancing trees and seating invites people to linger. To the south, open terraces will be created with a view of the Inde. Trees that are compatible with the urban climate and the integration of the local water balance into natural circulation systems ensure sustainability. Green roofs, vegetation and riverbank areas delay runoff and improve the microclimate.

Organization of use
The building is based on a modular construction grid of 8.1m x 8.1m x 4m or 5m on the first floor. All usage units are flexibly adaptable. The Innovation Mile connects the floors via a spacious staircase and promotes interaction. Upper floors offer communication areas, the first floor presentation areas. A café at the main entrance creates an inviting entrance. Space-intensive uses and laboratories are located on the first floor, while offices on the upper floors offer units from 30m² to over 1500m² and can also be divided and combined.

ONI is located adjacent to Tirana's Pazari i Ri (New Bazaar), in the heart of the old town and close to Kokonozi Mosque and the iconic Skanderberg Square. Pazari i Ri, a historically significant market, recently underwent a significant transformation to include a dynamic center for shopping, dining, and cultural activities. ONI continues that transformation.

Rather than creating a closed and isolated tower, our design's extroverted facades are open to the surrounding streets. This welcoming attitude reflects the nature of the neighborhood, which is characterized by commerce, socializing and enjoyment of urban life. By embracing and responding to this context, the plinth works to foster a sense of community and connection, promoting interaction and engagement among residents and the city.

Above the commercial plinth rises a striking residential tower which ingeniously combines apartments and penthouses. Playful setbacks transform the facade shape, reducing the perception of mass and creating an elegant silhouette which echoes and complements its surroundings. Meanwhile the relationship between the residential spaces and their commercial neighbors adds an exciting dimension, fostering a vibrant community atmosphere and creating opportunities for social interaction and commerce.

This forward-thinking design concept not only enhances the functionality of the building but also contributes to the overall urban fabric and residents' quality of life, enriching the surrounding neighborhood and adding a new hotspot to this lively neighborhood.

The proposal for the revitalization of Königstrasse 1ab is based on the following 5 guiding design themes:

Development of a building structure that completes the ensemble of the hotel and Königsstraße 1c, which incorporates heights and gradations, creates addresses and forms the prelude to Königstraße through its orientation towards the train station.

Creation of lively, green passages with small-scale retail, gastronomy and areas for culture and events in the interior of the ensemble and a generous setback on Königstraße to provide more space for planting and passers-by.

Enabling maximum exchange between inside and outside through diverse and generous entrances and transparent façades.

Creating modern retail, office and restaurant layouts that can react flexibly to changing future requirements.

Reuse of the existing load-bearing structure and individual components to minimize energy consumption and thus reduce CO2 emissions.

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.

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.

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.

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.
