4000 Old Rancheria Road

A peaceful world of your own just 30 miles from San Francisco. Set on 15.5 acres beside Skywalker Ranch and MALT-protected land, this gated Spanish-style estate blends timeless design with modern, off-grid living. Spanning 5,689 sq ft, the reimagined single-level main home and guest house are designed for seamless indoor-outdoor living. Start your day with coffee on the patio, hike the private 1.5-mile trail loop, pause at the yoga platform, then unwind with a cedar hot tub soak, sauna, or open-air shower under the trees. The 3BD/3.5BA main home features a dramatic great room with soaring ceilings and exposed Incense Cedar beams. A remodeled chef's kitchen, media room, and library offer space to gather or retreat, while the tranquil primary suite opens to the outdoors with a spa-like bath. French doors lead to patios with sweeping views, antique terracotta tile, radiant heat, and Marvin windows throughout. The 1BD/1BA guest house includes its own kitchen, updated bath, and private deck. Designed for self-sufficiency without sacrificing elegance, the property features a state-of-the-art solar power system paired with a commercial-grade backup generator, 20,000-gallon water storage, fire suppression, and approved pool plans. A rare West Marin retreat offering privacy, peace, and purposeful living.
