40 Mountain Lane

Welcome to 40 Mountain Lane, a handcrafted retreat set on the slopes of Mt. Tamalpais. This Mill Valley sanctuary blends custom artistry with its natural surroundings, showcasing redwood ceilings, rich wood detailing, and unique architectural features throughout the home. The main living and dining spaces are wrapped in floor to ceiling windows that frame a lush, park-like setting with Ipe decking and a mature lemon tree below. The chef's kitchen features custom cabinetry, granite countertops, and Viking Professional appliances. The primary suite captures sweeping views of the trees, the Bay, and hills beyond. Additional living spaces include a family room/lounge near the entry and an ultra-cool A-frame lofted bedroom with it's own dedicated bathroom. Making your way outside, the expansive deck offers a hot tub, sauna, and outdoor shower, creating a private haven connected to the surrounding landscape. Thoughtful upgrades include owned solar with large capacity battery backup, a high efficiency heat pump with air conditioning, a new metal roof, and an oversized garage equipped with EV charging. Close to world-class hiking and biking trails, Muir Woods, and downtown Mill Valley, 40 Mountain Lane offers a rare blend of craftsmanship, comfort, and natural beauty.
