This three-level home, with approximately 9,235 square feet of living space, was originally built circa 1904 by C.O. Perry, a wealthy San Francisco banker. The home underwent a $30 million restoration to retain its original architectural detail while bringing the property into the 21st century. Secluded on Belvedere Island's southeastern crest, the Greek Revival-style masterpiece offers unobstructed 270-degree views that encompass the San Francisco city skyline, the Golden Gate and Bay Bridges, Angel Island and the picturesque waters of the bay.
