150 W Oak Knoll Drive

Welcome to a once-in-a-generation sanctuary at 150 W Oak Knoll Drive, situated just moments from the entrance to Sleepy Hollow, San Anselmo. Crested on a grand knoll top across over three extraordinary acres of land, this established compound features three independent dwellings alongside absolute privacy, unmatched scale, and commanding, unobstructed views stretching across Mt. Tam, Mt. Baldy, the San Francisco skyline, the Bay, and beyond. Masterfully designed with flawless indoor/outdoor flow connecting every space to expansive terraces and vibrant grounds, this property offers a rare combination of close-in convenience and multi-generational resort living. The ~3,550 SF single-level main house boasts 4 en suite bedrooms (one styled as a library), 3 full & 2 half baths, moody redwood walls, formal living and dining rooms soaking up vistas, an updated kitchen with breakfast room, entertaining bar, fireplace, massive mudroom, and workshop. A detached 2 BR / 1.5 BA ADU (~818 SF) and a private 1 BR / 1 BA in-law unit (~673 SF) with an updated kitchen and Mt. Tam view deck offer endless versatility. The glorious grounds feature a saltwater pool with an outdoor kitchen, expansive entertaining patio, hot tub, gazebo, a massive limestone terrace anchored by a custom Philippine sugar-bowl fire pit, and an extraordinary outdoor glass atrium crowned by a 70-year-old wisteria. Sustainable, self-sufficient living defines the estate with an owned 18 kW solar system, EV charger, composting station, and a private well for irrigation. Enjoy flourishing vegetable gardens, an extensive fruit/nut orchard, greenhouse, chicken coop, kennel area, and an abundance of usable land ready for your personal vision. Designed for grand-scale entertaining, the property includes a sweeping circular driveway, 3-car garage, and dedicated parking for all your recreational toys, boats, or RVs. Close to open space, hiking, and biking trails, and located in the coveted RVSD school district and close to San Domenico and Hidden Valley schools. An irreplaceable piece of Marin history where world-class views meet pure, uncompromised soul. More than just a property, 150 W Oak Knoll Drive is a rare, enduring sanctuary -a canvas for grand gatherings, quiet moments, and a lifetime of shared memories on one of Marin's premier sites. This is where legacy lives, and where dreams are dreamt.
