To create additional space for our customer we put on an existing three story high building a new penthouse. The new insulated facade connect the old with the new extension to create one visual unit. On top of it an energy efficient roof is installed. The penthouse is built on a steel frame work awnd recessed from the three sunny sides of the existing building. The interior from the kitchen to the bath is designed according the needs and wishes of our customer. Living and dining together with the kitchen are combined into one unit while the bedroom is separate. The few doors are specially designed with aluminum profiles. Warm colors (maple floor, furniture) contrast with matte painted steel, translucent and opaque glass, aluminum, stone and white stucco lustro. The furniture provide the accent colors. The interplay of natural and artificial light defines the specific quality of this house.
