The first in a series of three buildings, each intended as a manifesto, that O.M. Ungers designed for his family (and in this case for his company, too). It sparked a debate in Germany: Ungers was accused of creating a house that was too “Expressionist” and sculptural/personal. Inside, only the corridors are stone facing. Banham included it in his book on brutalism in 1966.
