Situated in one of Tiburon's most coveted enclaves, this architectural estate captures stunning Golden Gate, SF skyline, Mt. Tam, and sweeping water views. Set on 1.23 acres of privacy, the Sandy Walker-designed residence lives like a resort with lush mature grounds and a striking 116' x 56' tennis court suspended above the bay. Inside, 5,575 sq ft of light-filled living unfolds from a dramatic double-height entry with curved staircase and 16-ft skylight. The upper level showcases refined formal spaces, an airy family room, and a grand chef's kitchen opening to view terraces, plus a luxe primary suite with spa-like bath and custom wardrobe. The lower level offers flexibility with a large office, three ensuite bedrooms including a private-entry guest retreat and a lounge that flows to manicured outdoor spaces. A 3-car garage and motor court add ease. Luxury features include an elevator, wine room, three fireplaces, white oak flooring, two powder rooms, spa terrace, level lawn, and fully integrated smart-home systems (Lutron, Savant, Sonos, whole-home WiFi, zoned HVAC). Minutes to SF, world-class dining, yacht clubs, Tiburon award-winning schools and scenic trails - this is Tiburon living at its finest.
