Luxury Property Auction: 25-31 August. Accepting starting bids through 24 August. Starting bids expected between $8M-$12M. Earn an incentive by 24 August. A meticulously crafted villa graces the southwestern shores of Belvedere Island, with unobstructed views spanning the San Francisco skyline to the Golden Gate Bridge, Sausalito, and Mount Tamalpais. Designed by architect Andrew Skurman and completed in 2008 by Red Horse Constructors, the estate channels the elegance of Portofino's historic villas through centuries-old patterned oak floors, hand-hewn cobblestone, and terra cotta finishes. A rare private pier, boat dock with lift, and boathouse extend onto San Francisco Bay, while a Swiss-engineered elevator glides from the gated entry to the front door. The full-floor primary suite offers sweeping water views, dual bathrooms, and a flexible adjoining room. Two additional ensuite bedrooms, an entertainment room with dry bar, and direct beach access complete the lower level. A detached guest casita, soundproofed garage, and included fifty-one-foot motor yacht with a Pier 39 slip round out this rare bayfront legacy.
