This turn-of-the-century residence sits hillside just below Buena Vista Park. An extensive renovation called for the entire structure to be lifted and excavated beneath to create two additional stories. Coupled with the addition of a master suite and roof deck atop the original footprint, along with the use of steel frames for an open floor plan, the residence boasts unobstructed views of downtown San Francisco and the East Bay. JYASF provided both the structural design and excavation engineering.
