The house, including the roof, consists of a load-bearing, outer shell of reinforced concrete, which is profiled on its outer sides by strips inserted into the formwork. The window openings are components of the building structure and are developed in their position from the visual relations and the disposition of the house on the property. In addition to these peculiarities, the oblique position of the ridge oft he roof in the floor plan, with the resulting HP surfaces, transforms the outline of the classical double-pitched roof house into a complex figure. The slight angle in the rectangle plan creates also a varity of surprising spacial relations in the upper floor.
