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 cafés, 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.

Neighborhood
Nestled at the foot of Mount Tamalpais, homes in this Marin County city range from 500-square-foot hunter's cabins to multimillion-dollar mansions tucked away on winding, narrow lanes under the redwoods.
Coffee is king in Mill Valley. Downtown, three separate coffee shops do a brisk business. At the Depot, as the sunny town center is called, moms with strollers, kids on tricycles, and teenagers kicking hacky sacks relax in the open-air plaza, which now houses an independent bookstore and cafe. The Depot is also a jumping-off spot for hikers and mountain bikers heading up the slopes of Mount Tamalpais. Nightlife in Mill Valley is anchored by Sweetwater Music Hall, which hosts many well-known musical acts.
