About this House

Set among towering redwoods on a quiet Mill Valley street, this one-of-a-kind home offers something rare: the feeling of living in a private forest retreat while staying moments from town, schools, parks, and daily conveniences. Thoughtfully designed with Zen-inspired outdoor spaces, two expansive decks, and treetop views from nearly every room, the home invites a slower, more connected way of living- morning coffee in the trees, family dinners under the canopy, and weekends filled with fresh air and adventure. A welcoming front deck leads into the main living level, where the living, dining, and kitchen spaces flow in an open-concept layout filled with natural light from oversized windows and skylights. The chef's kitchen features granite countertops, custom wood cabinetry, premium stainless appliances, and a generous island for gathering, homework, and casual meals. Rear deck access makes indoor-outdoor entertaining effortless. Downstairs, the private primary suite feels like a true sanctuary, opening to its own secluded deck. The newly renovated spa-style bath includes a deep porcelain soaking tub, heated shower floors, multiple shower heads, custom teak detailing, and a gray water diverter system that can nourish the surrounding redwoods. An additional bedrooms and a full bath complete this level, including a spacious and flexible third bedroom with a built-in office area, custom Murphy bed, generous storage, and floor-to-ceiling frameless windows and doors overlooking the terraced garden. A significant value-add: this property includes two parcels on a street-to-street lot (one APN), creating potential for an ADU with separate Florence Street accessideal for guests, extended family, an au pair suite, home office, or future income opportunity. With direct proximity to the iconic Dipsea Trail stairs, nearby parks, top-rated schools, and vibrant downtown Mill Valley, this home delivers an exceptional blend of privacy, elegance, and everyday livability for families who want both nature and community.

    "The neighbors are friendly and the views are great. this neighborhood is positioned in the middle of the Dipsea, Cypress, and Old Pipeline Trails, so running, hiking, and biking is just out your front door. In the center of the neighborhood there's a large permanent designated Open Space Park Area that used to be the Old Mill Valley Reservoir that people, kids, and dogs walk and play in. Their are only 12 houses on the private road, so there's not a lot of traffic and it's quiet and peaceful. Once a year there's an annual neighborhood block party at the end of Edgewood Ave. "
