Featured in the AIA San Francisco 2009 Home Tour, this residence in San Francisco’s Glen Park neighborhood underwent a full seismic retrofit and new third story addition.   Set in a steeply sloped hillside, the project­ included extensive rear yard improvements, terraced gardens and a steel bridge that connects the living spaces to the outdoors.  A new roof deck takes advantage of the dramatic downtown views.  Interior highlights include a custom stair “ribbon” of steel and kumaroo wood, a built-in wine cellar, and dumbwaiter on two levels.
