There are very few places in the world where land, water, and light conspire to create something that cannot be repeated. Set at the water's edge, this is one of few Belvedere Island estates built in an unbroken descent from the road all the way down to the Bay. A cinematic panorama - the San Francisco skyline, the Golden Gate Bridge, the Marin Headlands, Sausalito, and Mount Tamalpais - shifts with every hour of light. Expanses of glass draw the horizon into every room. Terraces extend the living outward. Set along a private road and discreetly positioned from view, the property offers a world unto itself, while remaining moments from San Francisco. The sound of the water. Salt air through open doors. Birds and marine life moving through the Bay. The silent passage of boats. A shoreline that feels improbably your own. Beneath it all: an extraordinary feat of engineering, years in the making, built to hold this singular position at the edge of the water for generations. Conceived as a deeply personal home designed for the sellers themselves, every decision was guided by long-term ownership. Newly completed in 2026, modern amenities and finishes are executed to an exceptional standard. On the water's edge.
