The existing urban situation is characterised by the coexistence of different building types—resulting in an unsteady spatial structure without a clear layout. Our design integrates into the one- to two-storey buildings, supplements and reorganises the existing building parts and clearly structures the exterior spaces into public and semi-public areas. “Continued construction” is the central idea of the design, which characterises the approach to the existing building structure of the main and adjoining building in floor plan, façade, and structural concept. The existing building, in which the spacious corridors and long routes are particularly striking, will be gutted and reorganised. The new building adjoins the existing building and expands it with new spatial constellations that give the whole a new identity.
