This recently rebuilt contemporary home (completed in 2016) sits on a secluded acre with sweeping views of Belvedere Lagoon and the San Francisco skyline. Surrounded by majestic oaks, it offers privacy, serenity, and refined design in a tranquil, park-like setting. Inside, wide-plank hardwood floors anchor the dramatic entry and main level. The spacious living room features custom built-ins, a gas fireplace, and surround sound. The chef's kitchen includes a butcher block island, farmhouse sink, dual ovens, walk-in pantry, and flows into the dining area and glass-enclosed, 550-bottle wine cellar. The primary suite is a retreat with abundance of natural light, heated bathroom floors, soaking tub, dual vanities, custom cabinetry, and dual closets. Downstairs are three en-suite bedrooms, a media room, large laundry, and 1,225 sq ft of finished storage. The bottom level can be an office, guest suite, creative space or all 3! It includes a lounge with designer bath, and opens to a 1,000 sq ft patio with above ground hot tub. Expansive wraparound decks offer panoramic Bay and city views. A vegetable garden, rainwater system, wine barrel bar, smart-home tech, and full-home generator complete this Tiburon sanctuary where luxury meets nature.
