Unlike most architects of the Neues Bauen movement, Alker did not opt for a stringent linear construction style, but skilfully grouped the apartment blocks as a homogeneous large form around a large shared inner courtyard. The staggered block corners, which allow good lighting of the interior spaces, and the central gate towers, which are emphasised as the visual joint of the block, are special. The north side with its monumental glass façade forms the end of the block. Egon Eiermann once had his office here.
