The quarter on Marckmannstrasse in Hamburg-Rothenburgsort is a heterogeneous ensemble of post-war residential buildings and low-rise warehouses. The aim of the design is to create a dense, urban-looking quarter with clearly defined street, square, and courtyard situations. The size and cubature of the new buildings are based on the block structures of the pre-war period, but at the same time seek a dialogue with the existing buildings. As a result, the building heights develop, on the one hand, from urban planning considerations to frame the street space and, on the other hand, from reacting to the existing building opposite (staggering). Clearly defined public outdoor areas as well as attractive inner courtyard situations for semi-public and private use are laid out. However, we avoid reconstructing the typical closed block edge of the Wilhelminian period. The solitary character of the independent, compact building complexes remains clearly recognisable. At the same time, the permeability of the structural arrangement generates numerous visual references between the buildings, connects them with attractive open spaces and thus unites them to form a strong, identity-generating urban ensemble.
