The project is an extension of a 1950s office tower in Berlin with a twofold goal: to reconnect the isolated tower with the (current and historical) city fabric and to become a prototype of exemplary energy performance for office buildings. The new connection to context is achieved through a heterogenous composition of volumes that take cues both from the baroque layer of the city (plinth) and from the late modernist layer (slab). The energy performance concept is based on a double skin concept and an aerodynamic ventilation fin at the top of the slab.

The C10 Tower was originally built in the 1960s. In 2008 Staab Architekten undertook the refurbishment and renovation of the building, with a focus on building performance.
