Theo van Doesburg was ordered to take care of the design together with Jean Arp and his wife Sophie Taeuber-Arp. Between 1926 and 1928 they will apply the principles of the dutch movement De Stijl (very popular in Europe at the time) to the design of the place and the decoration.
From an artistic point of view, it was one of the most ambitious avant-garde projects of the 1920's. Some qualify the enterior as the "Sistine Chapel of modern art".
