Tucked away on a flat, flag-shaped lot for ultimate privacy, this hidden 1957 retreat offers the best of indoor-outdoor California living. Surrounded by mature hedges and thoughtful landscaping, the home sits on a generous 14,000 sq ft lot and features a 2-bedroom, 2-bathroom main residence, a detached 1-bedroom guest house, and resort-style outdoor amenities that make everyday living feel like a vacation.
Step inside the 1,800+ sq ft main home and you’re greeted by a warm, modern interior with hardwood floors, custom built-ins, and expansive glass that connects you to the outdoors. A custom glass pivot door leads to the living room deck, while a decorative gas fireplace adds charm and comfort. The kitchen is beautifully appointed with Caesarstone countertops, soft-close cabinetry, and high-end appliances, including a Gaggenau refrigerator, oven, and cooktop, and a Bosch dishwasher. A Heath Ceramics tile backsplash adds a timeless touch. Adjacent, a built-in laundry room provides quiet efficiency and smart storage.
The primary suite offers serene views and privacy, while the second bedroom and bathroom continue the home’s cohesive, thoughtful design.
The detached guest house mirrors the quality of the main home, offering a private 1-bedroom, 1-bathroom layout ideal for visitors, extended stays, or a home office. A two-car covered carport and separate storage shed add functionality and potential.
The south-facing garden is where this property truly shines. A peanut-shaped, heated pool and integrated spa (wifi-controlled) are surrounded by on-grade decks, custom Tucci umbrellas, and a sailcloth canopy for shade. Entertain effortlessly with a plumbed gas BBQ, exterior Bose speakers, and ambient low-voltage lighting throughout. The entire property is irrigated and features extensive drainage work for peace of mind.
Whether you're relaxing in the spa, enjoying sunset dinners on the deck, or exploring expansion potential, this home offers a rare combination of charm, privacy, and potential in a prime Marin location.

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.
