Mill Valley has long dominated lists of the nation’s most desirable zip codes. Both MSN and Forbes have nationally ranked the Marin County town, where million dollar homes are as commonplace as the redwoods dotting the narrow wooded canyons and eastern slopes of Mt. Tam. Mill Valley’s desirability lies in its proximity to San Francisco—just about a 10 minute drive away—and its unmatched opportunities for outdoor recreation in the Golden Gate National Recreation Area, Muir Woods National Monument and Mount Tamalpais State Park. It’s also what led Smithsonian magazine to name it fourth among their 20 Best Small Towns in America in 2012 and CNN/Money and Money magazine to rank it No. 10 among 100 Best Places to Live in the United States in 2005. Not surprisingly, homes with a Mill Valley address command a premium. And homes with space—a half-acre lot, to be exact? Well, they command an even higher premium, as you can see.


This gated estate, priced at $5,850,000, offers approximately 4,595 square feet of sumptuous living space. The contemporary-meets-traditional residence was a complete rebuild by renowned firm Sutton Suzuki Architects, which was finished in 2001. Drawing inspiration from the spirit of the natural surroundings and a south-facing orientation in Mill Valley’s Middle Ridge neighborhood, the home blends some of the original iron details from the 1920s-era cottage with modern elements such as a skylight in the sun-filled solarium (a.k.a the breakfast room), Brazilian cherry wood and limestone flooring, plus state-of-the-art amenities such as double ovens, built-in espresso machine and stainless steel appliances.


“The result is a timeless and sophisticated design,” says listing agent Joshua Deitch of Coldwell Banker Residential Brokerage in Mill Valley Downtown.  “The two-story floorplan allows for ease of entertaining, with five bedrooms, five bathrooms, a formal living room, a chef’s kitchen, breakfast room, a family room off the kitchen, an office, a second family room, a 1,100-bottle wine room, laundry room and two-car garage.”

The residence’s southern exposure allows for vast views of the Bay Bridge and San Francisco—meant to be enjoyed across multiple outdoor living spaces amidst mature oak and olive trees. Custom stonework with slate pathways meander throughout the grounds, creating an atmosphere of “high-end resort living” says Deitch.

Additionally, pool and hardscape plans have been designed by local landscape architect Jim Bradanini, to enhance the experience. Meanwhile, Deitch notes that the driveway has also undergone extensive renovation and improvement since last being on the market—which only adds to its real estate value.  Another value? The home is intensely private with views stretching across bucolic Open Space to the Bay. Yet the lot size is what really makes this residence unique and valuable. Deitch says it is not easy to find a lot and home of this size in Mill Valley.

From the half-acre lot to the spectacular views and resort-style surroundings, this residence just may be one of the most desirable places to call home in one of the most desirable places to live in the nation.
