We provided the architectural and landscape design for the alteration and addition to a Hank Schubart-designed home in the Pacific Heights neighborhood of San Francisco. Sited on a steep corner property, the 7,000-square-foot home features expansive views to Alcatraz and the Golden Gate Bridge, as well as a retractable 20’ x 20’ skylight. Built in 1963, the light-filled home stands as a modern counterpoint to the Beaux-Arts architectural tradition of San Francisco. To expand the home, we added a third level with an open floor plan below the existing two-level structure and introduced an exterior garden at the lower living level. The resulting three-level home offers a simple plan layout with a neutral palette of finish materials that underscore the natural beauty and drama of the vista.
