This 2,100 sq. ft. contemporary house designed by Miami based architecture firm SB Architects, located San Fransisco California. The site originally housed a single structure – a one-story, one-bedroom home over a two-car garage, constructed in 1931 and totaling only 550 square feet of living space. This house created with a careful eye toward sustainability, this home is Tier Two Energy Star certified, making it over 35% more efficient than California Title 24 requirements. A 95% efficient gas boiler supplies domestic hot water and hydronic heating, and a 2.5-kilowatt photovotaic system with net metering provides solar energy, while energy star appliances and water efficient plumbing fixtures throughout ensure an efficient use of resources.
The naturally sloping site inspired the idea of a focal stair core wrapped by private areas and topped by a dramatic skylight, bathing the interiors in natural light and forming a direct link between through the private spaces on the entry level and the upper-level public spaces. The corner location and internal organization of space created an exterior expression that broke free of horizontal restraints to create a blend of horizontal and vertical lines, punctuated by a strong cantilevered roof. Locating the main living spaces on the top floor afforded dramatic views of the San Francisco skyline and garnered abundant natural light, significantly decreasing electricity use. A rainscreen system supports Ipe banding on the exterior façade, while walnut flooring and cabinets combine with cedar cladding on interior ceilings and exterior soffits to bring warmth to the interiors.
“This urban infill site in San Francisco presented a unique opportunity to create a new, free-standing home, while maintaining the site’s existing structure as a separate residential unit.” – Photos by Bruce Damonte
