The aim of the redevelopment was to adapt the Civic Hall to today’s functional requirements regarding public buildings and to upgrade its architecture. The central components of the redevelopment were the foyer, the Small Hall, the restaurant and the conference rooms, while the Large Hall required no refurbishment. A great challenge lay in combining the old with the new in such a way as to create a unity of design – parts of the new functional areas are interlocking with the existing fabric of the building, so giving rise to fluid transitions. The exterior of the Civic Hall was given a completely new appearance: The two-storey glass façade of the entrance hall with its striking folded shape delineates an expressive edge to the building and indicates transparency and openness towards the town. This redevelopment meets the latest technical and energy standards: despite being significantly extended in terms of area, it excels in lower energy consumption.
