Schlump One Hamburg by J Mayer H
German practice J Mayer H has replaced the gridded facade of a 1950s office building with organically curved glass and white render.

"We tried to design a facade that would be a bit more free, something less strict and linear" explained Wilko Hoffmann of J Mayer H.

Located above the Schlump underground station in west Hamburg, Schlump One is a seven storey building and the architects have extended it to accommodate more offices and the facilities for a private university.

The curved forms continue inside the building, where partitions have rounded openings that form surfaces beside the corridors.

Combined with the extension, the building has a U-shaped plan that wraps around a courtyard at the rear.

The building’s facade has been completely renovated and redesigned to form a single unit that freely interprets the original building’s 1950s linear design.

The organic formal language of the facade is continued in the design of interiors.
