Video Tour


3 Bedrooms | 6 Bathrooms | 4,205 Square Feet | $14,900,000


Floating above San Francisco Bay, this incomparable waterfront Corinthian Island home is truly breathtaking. The landscape is reminiscent of Portofino, and the lifestyle is quintessential California.

The house was custom built in 2009 for a well-known inventor and yacht racer, and extensively remodeled in 2015 by another tech titan, also known in international yacht racing circles. Awash in sun and expansive water and city views, the sleek three bedroom, six bath home blends architectural design, style, function, and luxury.

Walls of glass frame the San Francisco Bay and the city skyline in the spacious great room, featuring a custom kitchen, dining, sitting, and game area. The glass walls fold away, allowing the great room to spill out onto the west-facing deck for indoor-outdoor entertaining. 

The next level down is the gracious premier bedroom suite with another wall of disappearing glass doors and a view deck, as well as a second en suite bedroom. One more flight down is the third en suite bedroom with water views, adjacent to a spacious family/living/entertaining room with a wet bar.

The lowest level features a massive deck with a custom outdoor bar, a jet swimming pool and a spa, an outdoor shower, and a bathroom. A large electric ramp leads to a floating dock with power and water. At the dock is a 12,000 lb. boat lift.   

At the street level is a one car garage, one covered parking spot, and off street parking for two more cars. The home comes fully furnished, with all finishes and furniture custom designed by celebrated Juan Montoya Design. An elevator services all floors of the home, from the great room atop, to the deck and dock below.

This architectural masterpiece is a ten minute boat ride by private yacht to San Francisco. It is also within walking distance of the renowned San Francisco Yacht Club in Belvedere and Corinthian Yacht Club in Tiburon, as well as downtown Tiburon's shops, restaurants, award-winning schools, and frequent ferries to San Francisco and Angel Island. This is a dream home for yachters and all those who desire the ultimate southern Marin lifestyle.

With waterfront vistas that rival the Côte d'Azur, Belvedere is one of Marin's most exclusive enclaves. Large, historic homes perched on hillsides with commanding views of San Francisco Bay define Belvedere, one of Marin County and the Bay Area’s most desirable communities.

This tiny city of 2,200 residents is located on two former islands now filled in with causeways and separated by a private lagoon lined with waterfront homes. The world-famous San Francisco Yacht Club calls Belvedere home. Outdoor concerts are held in Belvedere Park throughout the summer, and Belvedere Playground is a popular spot for the young. Belvedere shares tony shops, restaurants, and municipal resources with neighboring Tiburon. The Belvedere Tiburon Library hosts almost 1,000 programs a year for all ages, and the annual Tiburon International Film Festival brings films from around the world.

Belvedere students attend the outstanding public schools in neighboring Tiburon, rated among the best in the state. Reed Union School District covers grades Kindergarten through 8th. High schoolers primarily attend Redwood High School, but are able to access the other schools in the Tamalpais Union High School District.
