Location: Nob Hill, San Francisco, California
Project size: 6,300 square feet
Site size: 1,840 square feet
Program: The client commissioned the architect to build a two-unit building—to be used by one owner—that maximizes the space and views of a small vacant lot in an older San Francisco neighborhood. The new building was designed to be distinctive, yet to also harmonize with the surrounding residential area.
Solution: The three-story urban house sits at the corner of two streets sloping downhill from Grace Cathedral and Huntington Park. The basement has a garage, connection to the elevator, stairs, and utility rooms. The first floor is a separate living level for either guests or extended family members. The main unit is composed of the second and third levels; the second floor has three bedrooms and three baths, while the third floor has the main living, dining, and kitchen areas with views of the Transamerica Pyramid and San Francisco Bay. The entire roof is a deck that has views of Nob Hill, Coit Tower, the Bay Bridge, and San Francisco’s downtown.
Construction and materials: The building has a mat slab foundation, steel frames, wood frame infill, and steel windows set in Limestone cladding; the same stone was repeated inside the baths. White oak wood floors and traditional baseboards were used throughout.
