Welcome to The Secret Acre. Within Fairfax is one of Marin's rarest luxury offerings not seen on the market for a long time. All on one-level and wrapped in nearly an acre of sunlit, flat grounds, this is 4+ bedroom estate with a 5th Bedroom-ADU cottage. Included in this floor plan is separate a dedicated office. This resort-like home invites you to slow down, spread out, and thrive. Almost 3,400 sq ft flows seamlessly to the outdoors, where a huge lawn and shimmering pool and poolhouse are just steps away. The backyard includes a greenhouse, and a radiant vegetable garden making the entire property feel like a lux oasis for off-the-grid living. There is a spacious garage which converts to a state-of-the-art gym. What makes this so special is the separate 1-bedroom ADU perfect for guests, work-from-home, or multi-generational comfort. And everything on one level. Nature lovers will relish direct access to West Marin's famed biking trails, proximity to top-rated schools and the secluded compound feel. Best of all, just a short stroll from downtown Fairfax, Marin's last true village, alive with cafes, live music, and destinations like Village Sake. This rare property is the ultimate family retreat: an idyllic lifestyle, minutes from the city yet worlds away
