Inspired by Claude-Nicolas Ledoux (French, 1736-1806) and his 1789 concept for a utopian gardener’s house in an ideal city (bottom), the Dresden “Ball House” was part of a labor exhibition called The Technical City. The six-story building contained a central atrium and an elevator to the restaurant at the top. Nazis later considered it to be degenerate art, and it was destroyed in 1938.
