About This Home

Perched among the trees on a half-acre lot in coveted Mill Valley, 321 Pine Hill offers a rare blend of modern design and natural charm. With its magical, sunny, treehouse-like setting, this beautifully remodeled home feels like a private retreat surrounded by lush greenery and filtered sunlight, yet just moments from town. Thoughtfully redesigned, the home features a large open great room, three gracious bedrooms, a fourth flex room, and a separate studio space. Floor-to-ceiling steel-framed windows and wide-plank white oak floors carry warmth and light throughout, while the custom window boxes cantilevered over the hillside in two bedrooms create suspended reading nooks in the trees. Two sunrooms anchor the design, where angled glass ceilings meet reclaimed wood beams overhead, luminous spaces that blur the boundary between indoors and out. The three spa-inspired bathrooms serve as standout features, each with a distinct material palette: handmade zellige tile and a freestanding soaking tub beneath a steel-framed window, a Moroccan terracotta-tiled powder room with a sculptural pedestal sink, and last a bath finished in terrazzo and patterned ceramic with matte black fixtures. Throughout, the design is warm and minimalist with natural materials and artisanal finishes. Multiple decks extend the living space outside at canopy height, where morning light filters through the oaks and the only sounds are birds and breeze. Arguably one of the best locations in Mill Valley, minutes from neighborhood favorites Hook Fish, Equator, Good Earth, and Junction, among the best Marin trails, and the first exit in Mill Valley for easy SF commuting. 321 Pine Hill offers a truly special living experience where design, nature, and modern living come together in peaceful harmony.
