A once-in-a-generation opportunity to own the storied Tomasini Ranch 440 extraordinary acres in the heart of West Marin offering unmatched privacy, sweeping natural beauty, and a legacy estate unlike any other. Set at the end of a private road, this remarkable property unfolds across rolling pastures, oak groves, open valleys, and dramatic ridgelines with breathtaking 360-degree views stretching from Mt. Tam to Tomales Bay. From nearly every vantage point, iconic West Marin landscapes and shimmering water views create a setting of rare serenity and scale. The jewel of the property is a custom-built 4-bedroom, 3-bath main residence perfectly positioned to capture panoramic vistas from every room. Designed with an open floor plan that seamlessly connects indoor and outdoor living, the home features custom tigerwood hardwood flooring, bespoke cabinetry, expansive decks and patios, and walls of glass framing the surrounding landscape. The luxurious primary suite offers stargazing through overhead skylights, while outside, a heated saltwater infinity pool seemingly disappears into the rolling hills beyond. Adding to the property's charm is the original 5-bedroom, 2-bathroom mid-century guest house, rich with timeless character and authentic design. A dramatic wall of windows frames water and hillside views, while original wood paneling, built-ins, and a double-sided stone fireplace evoke the warmth and simplicity of a bygone era. Thoughtfully positioned outdoor spaces include a sun-drenched front deck and a sheltered rear patio surrounded by Madrones, oaks, bays, and cedars fully immersing you in the beauty of the natural setting. Completing the estate is a 3,000-square-foot agricultural barn with lodging, ideal for ranch operations, creative pursuits, equipment storage, or extended guest accommodations. Private, peaceful, and impossibly scenic, Tomasini Ranch is more than a property it is a legacy compound where land, architecture, and nature exist in perfect harmony.
