This project transformed two small apartments on the top floor of a residential building designed by Paolo Nestler in the 1970s into a spacious penthouse. As part of the comprehensive core renovation, Arnold / Werner created in particular an open living area that not only forms the center of family life, but also gives the apartment a unique identity. 
Literally the focal point is the black-stained, floor-to-ceiling recessed wood furniture and wall coverings that wrap around the central plumbing core in a ribbon-like fashion. From the living area, this ribbon develops down the hallway and into the master bedroom. In contrast, the ceilings and all other walls, as well as the children's bedrooms, appear all white. The freestanding kitchen unit and white Italian marble master bath create a sensual sense of comfort - as do the oak hardwood floors and the delicate black or bronze door hardware and bathroom fixtures. Large, thresholdless sliding patio doors lead from all rooms to the wrap-around roof terrace, creating smooth transitions between indoors and outdoors.
