About This Home
A rare, sun-drenched mid-century retreat set on a 16,600 sqft, double lot with sweeping views across Tam Valley and the surrounding GGNRA ridge lines where privacy, scale, and seamless indoor-outdoor living come together just minutes from the best of Mill Valley. Walls of glass and clean architectural lines invite the outdoors in, creating a warm, light-filled flow designed equally for everyday living and vibrant entertaining. At the heart of the home, a beautifully appointed chef's kitchen with professional-grade Viking appliances opens seamlessly to generous living and dining spaces. The main level features a stunning primary suite with floor-to-ceiling windows framing panoramic views of Tam Valley and Muir Woods, along with a spa-inspired bath complete with soaking tub, walk-in shower, and sauna. A spacious guest bedroom, a refined modern bath, and a sunlit office or additional bedroom with private balcony complete the main level. The lower level offers exceptional flexibility, with a large family room opening directly to the gardens, three additional bedrooms, and two updated baths easily configured as a private guest or au pair suite all with their own entrance, ideal for multi-generational living, extended stays, or work-from-home independence. Set on expansive grounds with mature landscaping, fruit trees, bocce court, putting green, the property lives like a private retreat. Tucked away in a serene, natural setting, yet just moments from top-rated schools, Good Earth Market, Tam Junction's vibrant dining scene, and endless hiking and biking trails with San Francisco just minutes away this is a rare opportunity to live immersed in nature without sacrificing connection. Quintessential Mill Valley!
