On the site of the former Kindl brewery in Berlin's Neukölln district, the collaborative community and co-working space Impact Hub Berlin is opening for a new generation of entrepreneurs who focus on circular economy, sustainable food, diversity & inclusion and green tech. In addition to the building's use, its construction and choice of materials is based on a circular building method and is infused with an awareness of conserving resources. According to the credo “form follows availability”, the interior design reflects how the preservation of the existing building and the use of re-used, renewable and recycled materials can transform tomorrow's construction in a positive way.

The design of the space is based on the principles of New Work. The former warehouse is split into two levels by the installation of a wooden gallery. Public areas on the ground floor, such as the café, are also made accessible to local residents. Other spaces are reserved for Impact Hub Berlin members. In a nod to the history of the site, the industrial character of the existing building can still be felt. Without the hall losing any of its spaciousness, the central rooms allow for indirect zoning. Adapted to the different needs, there are different room styles suited to either noisy or quiet working environments. The open spaces encourage dialogue with others, but also feature spaces to retreat to for concentrated work. The result is a varied mix of team areas, open co-working, meeting rooms, lounge and a café with a terrace. Telephone boxes, meeting booths and seating niches are distributed throughout the levels, while studios, workshop rooms and labs can be found in the basement.

In an exploration of circular construction methods, the location takes into account aspects such as reusing of building components, flexibility, recycling material, facilitating future usage changes and creating versatile structures. Recyclable and reused materials, deconstructable and unmixed constructions and simple standards are used for the interior fittings. With the help of product and material passports, the elements used can be repurposed after disassembly. The process itself was accompanied by various workshops with the client and craftsmen to explore sustainable construction methods and experimental approaches in prototyping in order to reduce concerns and risks for all project stakeholders.

The innovative circular material concept of Impact Hub Berlin at CRCLR-House involves both "using materials as they are found" and "upcycling". Around 70 percent of the materials and products used are recycled, reused or renewable. High-quality reused and new renewable materials are used as they are. Damaged or uneven materials are treated to fit the design concept. Despite the simplicity and the use of diverse materials, the design hinges on clarity, homogeneity and a high-quality aesthetic.
