Private Bay-View Retreat Among the Redwoods. Set on a landscaped half-acre overlooking Richardson Bay, 108 Hacienda Drive is a meticulously updated residence offering exceptional privacy, understated elegance, and a seamless connection to its natural surroundings. Mature redwoods, lush gardens, and thoughtfully designed outdoor spaces create a serene setting just minutes from downtown Tiburon's waterfront, ferry, restaurants, shops, hiking trails, and Highway 101. The 2,974 square foot, four-bedroom, three-and-one-half-bath home is filled with natural light and finished with white oak hardwood floors, custom millwork, and quality appointments throughout. Expansive windows frame water and garden views, while sunlight filtering through the trees gives each room its own character. Soaring wood-clad cathedral ceilings and a dramatic stone fireplace define the living room, while bay views set the stage in the adjacent dining room, where a custom zebrawood sideboard adds warmth and craftsmanship. The kitchen anchors the home with quartz countertops, a generous center island, built-in Sub-Zero refrigeration, and a Miele oven paired with an induction cooktop; a sunny breakfast area looks through the redwoods toward the water. The adjoining family room, centered on its own fireplace, opens directly to a broad entertaining deck, an effortless blend of indoor and outdoor living. The primary suite is a true retreat: custom built-ins, a fitted walk-in closet, heated tile bathroom floors, dual vanities, a glass-enclosed shower, and a private deck with hot tub and outdoor shower, all bathed in morning light. Three additional bedrooms and well-appointed baths accommodate family and guests, with flexibility for a home office or creative studio. A separate finished guest suite with a full bath, private deck, and its own entrance adds versatility for visitors, extended family, or remote work. Owned solar with battery backup, EV charging, abundant storage, a two-car garage, generous off-street parking, and fully fenced 22,100 square foot grounds complete the offering. Impeccably maintained and thoughtfully enhanced, 108 Hacienda Drive delivers lasting quality in one of Tiburon's most tranquil settings.
