Perched at the edge of Belvedere Island on a near-private cul-de-sac, the Belvedere Sanctuary is a rare, world-class estate in one of the most coveted locations on San Francisco Bay. One of just six homes on the road, this extraordinary two-building residence offers sweeping panoramic views—from the Bay Bridge to the Golden Gate and Sausalito—creating the feeling of a private island retreat above the water.

Designed with bespoke finishes and timeless craftsmanship, the home features a custom infinity-edge pool, outdoor fireplace, stone terraces, and lush gardens ideal for refined entertaining or complete seclusion. An effortless indoor-outdoor flow, bronze railings, teak-framed windows, and hand-hewn wide-plank walnut floors reflect an Old World elegance paired with modern design. High ceilings and designer lighting enhance the light-filled interiors and dramatic vistas.

The primary suite is a sanctuary unto itself, with sitting area, custom closets, surround sound, and Golden Gate Bridge views from the shower. A private studio guest house with full amenities and garage mirrors the main residence’s elevated finishes, creating a seamless and versatile compound with dual entrances.

Set on the coveted tip of Belvedere Island, this distinguished enclave across the Bay from San Francisco offers one of California’s most exclusive lifestyles, complete with ferry service, two world-class yacht clubs, and a vibrant collection of shops and restaurants. With effortless access to San Francisco, Napa, the California coast, and Marin’s renowned hiking and biking trails, opportunities to own a home of this caliber are exceedingly rare.
