Incredible opportunity to own a stunning custom modern estate with sun-filled Mount Tam views on approx. 40 acres within the charming town of Fairfax. This rare property sits close to town yet feels miles away, with access to the ridgetop trails that wind through the rolling topography and scenery that make Marin County so special. On the property itself are multiple private walking trails that are wide and gently sloped, a fenced garden, an art shed and multiple gathering places, several with views of San Francisco, making this an amazing space for friends and family to retreat, recharge and explore the gorgeous land and views. The property includes two stunning and modern newer homes: a custom 4,457 sq ft main residence with 5 bedrooms, 4 full baths, a primary suite with a large view deck, a chef's kitchen, an oversized living room with 15' ceilings, radiant heated floors, walls of glass and stunning MtTam views, plus an infinity pool site with valley views. The separate 1 bedroom, 1 bath ADU offers modern finishes, radiant heat and its own light-filled living space. Should the new owner wish, this land also offers an exceptional opportunity to pursue a land-division strategy and notable development potential.
