For 25 years, the building in Karwe, a small village on Lake Neuruppin in Brandenburg, was an abandoned ruin, a reminder of the former location of the former GDR cooperative chain Konsum. In 2017, Johanna Meyer-Grohbrügge and Sebastian Behmann acquired the building and transformed it into a collaborative architectural project with their offices Meyer-Grohbrügge and Studio Other Spaces.

Sebastian Behmann founded Studio Other Spaces in Berlin in 2014 together with the artist Olafur Eliasson. The common interest in spatial experiments unites both founders and their disciplines and led them to a holistic approach that defines the studio to this day. For each project, spatial, historical, ecological, social and emotional parameters of the site and its users are researched at every stage of development. The planners continuously move between overall perspectives and a very detail-oriented level. They combine traditional tools, production methods and materials with state-of-the-art design tools, production methods and innovative media.

The building, which used to be a supermarket run by the GDR Konsum cooperative chain, is now a vacation home for a family. However, the new use is by no means intended to shield the property, on the contrary – the centrally located house is to remain an active part of village life. The design aims to blur the boundaries between public and private space. A possible subsequent use is considered at an early stage. The design by Meyer-Grohbrügge and Studio Other Spaces offers several options that easily reintegrate Konsum Karwe into the public space.
Central to the design of Konsum Karwe is the reuse of existing structures and working with sustainable yet contemporary materials. Following the principles of the circular system, most of the materials used remain raw and untreated so that they can be reused when the building’s use changes or at the end of its life. The main materials used, with their colors and textures – brick for the base and floor, brick for the walls and wood for the roof structure – also give the former supermarket a unique character.
In addition to materials, Meyer-Grohbrügge and Studio Other Spaces placed additional ecological solutions in the form of geothermal heating and a rainwater collection system. In order to make the rainwater system profitable, areas around the supermarket that were sealed during the GDR era were reopened. This enables natural drainage, which makes it possible to collect rainwater.
The renovation retains the structure of the building, but adds a new roof and a transparent shell. The new glass façade and roof provide the necessary insulation from the existing building. Above the former supermarket sales area, the two offices intervene more strongly in the roof landscape. In order to create an open inner courtyard, the architects completely removed the roof at this point. The resulting atrium becomes the central space of Konsum Karwe and connects all rooms with the roof garden.
The load of the green roof is transferred via the existing walls, which are additionally reinforced with steel girders for horizontal bracing. In this way, a lush green area was created, which is accessible via a spiral staircase. The roof garden and inner courtyard, the private parts of the vacation home, form a contrast to the surrounding landscape with their wild, rugged design. This creates a skillful interplay of courtyard, roof garden and surroundings in the overall perspective. They become a new, exciting visual element that complements the horizontality of the village.
The main materials used in the project – brick plinth and floors, brick walls and a wooden roof construction, as well as their colors and textures – give this house a unique visual identity.
The two offices are converting a supermarket into a residential building, a subsequent use that is not immediately obvious. The studio’s collaborative approach is evident in the design concept. The cautious approach, which does not change the character of the building, is combined with major interventions and current sustainability requirements. The result is a vacation home that simultaneously radiates GDR heritage and modernity and has been given a perspective through scenarios for subsequent use.
