A Rare Bayfront Offering Framed by Mt. Tam, Moments to Town!

$5,900,000

20 Bayshore Terrace, Tiburon
Set along the coveted Tiburon shoreline, this offering is defined by magnificent, unobstructed views over Richardson Bay—from Sausalito through Mt. Tamalpais—paired with mesmerizing sunsets. A private gate opens directly to the Bay Trail, making morning walks, bike rides into town, and daily connection to the shoreline part of an effortless routine. 

The home itself is a thoughtful expression of authenticity and craftsmanship, blending provenance materials with modern livability. Solid hand-hewn walnut floors, pegged hardwood detailing, a 17th-century French door set within a custom fruitwood arched entry, and 18th-century limestone fireplaces create a sense of history and substance that is both rare and enduring. Custom crystal sconces, a Belgian chandelier, curated lighting, Marvin wood windows, Andersen sliding doors, and Rocky Mountain hardware further elevate the home with a level of quality and finish that is both refined and lasting.

Designed for both comfort and versatility, the layout includes all primary living spaces on one level with no stairs from the entry. That includes the primary suite - an exceptionally private and luxurious retreat surrounded by the bay, with no homes or visible neighbors in its outlook. Here, sweeping water views, sunrises, and glowing evening light create a setting that feels both expansive and serene. The suite is complemented by two walk-in closets and a spa-like bathroom with a large picture window and radiant heated floors, all thoughtfully oriented to capture the natural beauty of the surroundings.

A newly permitted and well-integrated junior ADU offers flexibility for guests, extended family, an au pair, or caretaker, adapting effortlessly to evolving needs.
Beyond the interiors, the home embraces a true indoor–outdoor experience. Expansive openings invite the landscape in, while the outdoor spaces—complete with a deep pool and spa—become natural extensions of daily living. Full sun exposure enhances both the home and grounds, creating an environment that feels open, bright, and alive year-round.

Substantial system upgrades—including a new roof, solar, air conditioning, and an EV charger—provide modern efficiency and comfort behind the scenes, allowing the focus to remain on the experience itself.
Just beyond, a nearby grassy field and playground further enhance the lifestyle, offering open space and recreation moments from your door. All of this, just moments from town and with easy access to 101, yet feeling worlds away. Properties like this rarely come to market—not simply for their location, but for the unparalleled lifestyle they quietly deliver every day.

Neighborhood

Tiburon’s waterfront location makes it a prime destination for Marin County homebuyers. For a town of less than 10,000 residents, Tiburon offers a variety of activities that belies its small size. The annual Tiburon International Film Festival brings films from around the world. Residents enjoy shopping in the elegant boutiques along Ark Row, a leafy, block-long enclave of tiny shops that were once floating arks, and dining at the excellent restaurants along Main Street. For the nautically inclined, Tiburon's Corinthian Yacht Club hosts races on the bay. Ferries to San Francisco and Angel Island State Park leave from the dock at Tiburon. Tiburon's parks are strung out like pearls on a necklace along the water’s edge. Blackie's Pasture, named after an old swaybacked horse that once lived here, is a popular spot for hikers, joggers, bikers, moms with strollers, and dog walkers. On weekends, the parks fill up with soccer players of all ages.
