It begins with a sense of calm. Just moments from downtown Mill Valley, the pace changes, the noise softens. Majestic trees surround you. The air cools. There's a feeling here that's increasingly rare privacy, stillness, and connection to nature, all woven into the fabric of everyday life. And yet, just beyond the trees, one of the most beloved downtowns in Marin unfolds at your doorstep. Old Mill Park. The Mill Valley Public Library. The Dipsea Steps. Old Mill School. Downtown cafes, restaurants, wine bars - not to mention - miles of hiking and cycling trails that begin almost immediately from the house. It's the kind of location people spend years hoping to find a place where daily life feels walkable, grounded, and deeply connected to the outdoors. Designed by acclaimed local architecture firm OXB, the home itself feels equally intentional. Modern and architecturally striking, yet warm, understated, and incredibly livable. The single-level floor plan unfolds with ease, anchored by exposed steel and wood beam construction that brings both strength and warmth into the spaces. Walls of Fleetwood glass doors pocket seamlessly into the architecture, opening the main living areas to an expansive deck nestled among the redwoods. The relationship between indoor and outdoor living is effortless here. Morning coffee outside beneath the trees. Long dinners with the doors open. Quiet afternoons on the deck surrounded by the sounds of nature. The home invites a slower rhythm without ever sacrificing sophistication. Every finish feels carefully considered: radiant heat throughout, wide-plank oak floors, custom lighting, walnut and concrete countertops, Heath tile, a standing seam metal roof, and a beautifully appointed kitchen with Sub-Zero, Wolf, and Bosch appliances. Nothing feels excessive. Everything feels deliberate. Architecturally refined, but never cold. Private and immersed in nature, yet only moments from the energy and charm of downtown Mill Valley. Designed not simply to impress but to make everyday life feel exceptionally good. A complete set of recent reports and inspections are available upon request.
