The historic building complex of the former U.S. Patent Office Building in the heart of Washington DC is nowadays used as a museum. In the course of refurbishment the inner court was provided with a roof including the whole roof construction with steel columns, glazing and acoustic cladding. The curved roof construction with an area of approximately 39 x 84 m consists of welded and distorted steel columns, up to one meter high.
