The extension of the town hall from the 1960s in Berlin, Germany, was converted by SSP Ruthnick Architekten and technically as well as energetically updated to the latest technological standards. A special influence on the plans for the transformation of the listed ensemble was the preservation of the draft character of Fritz Bornemann (1912-2007). The conversion and interior renovation has created a striking example of preserving a building from the post-war modern era.
