441 Tamalpias

5 Beds | 4.5 Baths

Serenely positioned on the hillside overlooking the Valley, this modern, stunning, and sustainable home is the grown-up treehouse of your dreams. The home was conceived by the renowned architecture firm Zack and DeVito. With 4,000 square feet of living space spread over three impressive levels, the design meets function with a wonderful, generous, and flexible floor plan. 5 bedrooms (3 of which could be primary suites, an in-law or offices), 4.5 bathrooms, a gorgeous kitchen, formal dining area plus breakfast nook, a sun-soaked living room, and a casual media room. A wine cellar and in-deck spa add joie de vivre. A two-car garage is at street level with interior access to the home.
Nestled on a serene street and immersed in the beauty of the nature that surrounds, nearly every room connects to the outdoors with a copious amount of decks that wrap around this forest retreat.
Situated on a large lot, manicured paths lead to a charming creek and bucolic areas to relax and play.
Sustainability was at the forefront; Tesla solar, reclaimed and recycled materials, LED lighting, rainwater collection, and a design that perpetuates sustainability.
Minutes from downtown Mill Valley yet located on a street that sees more dog walkers headed to the trailhead than cars, 441 Tamalpais is a home unlike any other. It is the epitome of special.
912 Rhode Island is close to all the iconic Potrero Hill restaurants and a few blocks to freeway access and public transportation.
