Since the new construction does not lean on the existing structure, but is separated by a shadow gap, the villa still enjoyes its independence. The new volume, perfectly integrated into the hillside, is elongated and occupies the full width the plot. Through a slight rotation the new construction awerts from the existing building in order to direct the south facade to the sun and the panoramic view. The joint in the basement connects the extension with the existing building and serves as enclosed common room. The east and north façades are relatively closed because of the interior functional distribution; furthermore, the north side is designed to show the clear separation between the new and the existing building.
The building uses reduced colors and materials: the volume is coated with horizontal oxidized copper sheets of various width, large glazed surfaces bring the sun inside of the building, and the balconies are covered with larch wood. Copper and larch wood are exposed to a natural change of colour caused by the atmospheric influence of sun, rain and snow; this phenomena, in addition to the repetition of the wooden colour code of the Villa, accentuates the integration of the building in the natural enviromental.
