The architecture of the wooden house designed for the Berlin sawmill owner and building contractor Adolf Sommerfeld, designed by Gropius and Meyer in 1920, reflects the Expressionist-influenced beginnings of the Bauhaus. According to Gropius, the wood corresponded to ‘the primitive, initial state of our life that is being newly constructed’. All of the arts were included in the building in a programmatic way: for example, Joost Schmidt gave the beams a sculptural treatment, Josef Albers designed coloured glass windows, and Marcel Breuer designed some of the furniture.
