For more than 20 years, the protected ‘Marinehaus,‘ originally a union club for naval officers, was left neglected in the central Berlin neighborhood, Mitte.

Now the building, as a central part of the vision of the Berlin City Museum to establish a cultural cluster, is to be resurrected as a new museum typology. With a strong house-in-house concept, ADEPT wins the international competition ahead of 20 invited competitors.  

The  simple house-in-house concept creates synergy between the new community functions and the historical frame, already integrated in the urban context. 

The existing floors are removed and replaced by a new interior wooden structure, allowing visual connections between floors and a warm inclusive identity to the project. 

The careful transformation of the protected building is part of the future strategy for Stadtmuseum Berlin, that includes a new type of museum - a cultural pivot that anchors the museum in the neighborhood through exhibitions, workshops and as a community center for the locals. 

The design embraces both old and new: a new flexible interior structure that creates spaces for cultural activities and the local community, and at the same time a respectful re-use of the protected building.

The director of Stadtmuseum Berlin, Paul Spies, praises the winning proposal for its way to create an open and inviting contribution to public life in the city, embracing both everyday life and cultural communities. 

At the same time, the winning proposal underlines the vision of an innovative urban laboratory focusing on the many aspects of Berlin as a city.
