A new master bedroom suite addition to this hilltop ranch style house has been situated to take advantage of a spectacular vista of Mount Diablo and the intervening valley below. With the mountain visible while lying in bed, a vaulted ceiling expands the view while picking up on the vernacular of the existing house. This ceiling visually connects the bedroom with the bathroom through the use of high windows in the wall between the two rooms. These high windows are then repeated on the exterior wall of the bathroom, bringing in natural light while maintaining privacy. The other three bedrooms and a second master bathroom were also reconfigured.
