With quiet self-confidence, the new Alltours headquarters presents itself as a hybrid building for working and living between the Behrensbau and the adjacent residential development. The building blends naturally into the perimeter of the block on Mannesmannufer. The reference to the listed Behrensbau is established by the recurring arrangement of different readable "floor packages", the vertical window division and the tectonic joining of the base, main body and superstructure. The main building, characterized by its strong plasticity, rests on a glass plinth, which is offset in height.
