This extremely private and newly rebuilt home (completed 2016) is perched on a secluded acre with sweeping views of the Belvedere Lagoon and the San Francisco skyline, this contemporary masterpiece offers the ultimate in privacy, serenity, and sophisticated living. Surrounded by a canopy of majestic oaks, the residence blends breathtaking natural beauty with refined modern design in a park-like setting.

Step through the covered entry into a dramatic foyer anchored by striking stone-wrapped walls and wide-plank hardwood floors that flow effortlessly throughout the main level. The spacious living room is designed for both relaxation and entertaining, featuring custom built-ins, a sleek natural gas fireplace, and a state-of-the-art surround sound system.

At the heart of the home is a chef’s kitchen that combines style and function with a butcher block island, handcrafted range hood, dual wall ovens, a white cast iron farmhouse sink, built-in refrigerator/freezer, walk-in pantry, and open-concept flow into the adjacent dining and living spaces.

The formal dining room is anchored by a stunning 550-bottle climate-controlled wine cellar, enclosed in glass with floor-to-ceiling stonework — a showstopping focal point for dinner parties and wine tastings.

The luxurious primary suite is a true retreat, with walls of glass that frame iconic views and spa-like amenities including heated floors, a freestanding soaking tub, dual vanities, his-and-hers toilets, custom cabinetry, and dual walk-in closets.

On the lower level, a spacious family/media room with built-ins and surround sound is flanked by three elegant en-suite bedrooms, each offering premium finishes. A large laundry room with sink and laundry tub leads to a massive 1,225 sq ft of finished storage space — perfect for wine, gear, or hobby use.

The bottom floor offers flexible use with two rooms and a lounge with a full designer bath — ideal as a guest suite, office, creative studio or all 3! Step outside onto a 1,000 sq ft patio, ideal for alfresco entertaining, with direct access to the private backyard and panoramic views.

Expansive wraparound decks on each level — totaling over 1,240 sq ft — provide front-row seats to sunsets over the Bay and glittering city lights. The backyard is a peaceful escape, thoughtfully landscaped with a vegetable garden, rainwater harvesting, drip irrigation, and a rustic wine barrel bar that brings wine country charm home.

This fully integrated smart home offers room-by-room touchscreen controls, built-in ceiling speakers, CAT6 wiring, 24-hour surveillance, and a full-home automatic-start natural gas generator — delivering convenience, security, and ease at every turn.

This is more than a home — it’s a modern sanctuary where nature, luxury, and technology converge in perfect harmony.

Welcome to your Tiburon escape.
