University of Applied Sciences BT 21 Hamburg

The listed building, constructed in 1911-1914 by Fritz Schumacher, is part of the Berliner Tor campus, the main campus of the University of Applied Sciences. During the First World War, the building served as a reserve hospital, in the Second World War, the building was completely burnt out during the air raids of June 1943, the roof and upper floors were destroyed. Reconstruction of the main building began immediately after the end of the war. Up until the 1970s, the Schumacher Building was the central address for engineering in Hamburg. Today it houses the Department of Mechanical Engineering and Production at HAW Hamburg. Since 2015, DFZ has been entrusted with the renovation and maintenance work of the existing five-storey building. The measures include the entire safety renovation, moisture restoration, renovation of the roof and facade, numerous deconstruction measures with fire protection-compliant reconstruction, as well as the furnishing of all public areas. The uniqueness of the building is revealed in the differently coloured stone plaster surfaces, which were discovered under numerous layers of paint during a restoration study in 2003. In the course of the concrete renovation, the plaster ceilings, walls and pillars with original ornaments were uncovered and restored with elaborate retouching. In addition to the concrete renovation, the most recently completed construction phase includes the development of a lighting concept for the public areas. Based on historical context, a lighting series is in development which recalls the geometry of the wall and ceiling ornaments and interprets them in a discreetly contemporary form. All measures will be carried out in successive construction phases during ongoing operations in close consultation with the local historic buildings authority. Alle Maßnahmen werden in aufeinander folgenden Bauabschnitten im laufenden Betrieb in enger Absprache mit dem Denkmalschutzamt realisiert.
