Set on a generous parcel in one of Mill Valley’s most desirable residential pockets, 308 Marin Avenue is a newly constructed modern farmhouse that blends timeless design with thoughtful, contemporary living. Defined by clean architectural lines, warm finishes, and an exceptional indoor-outdoor connection, the home offers a rare combination of style, scale, and versatility. The main residence features four bedrooms and two and a half baths, thoughtfully designed for today’s lifestyle. At the center of the home, a light-filled kitchen flows seamlessly into the main living areas, anchored by a spacious family room that offers incredible flexibility—ideal as a media room, play space, or secondary lounge. A well-appointed pantry and dedicated laundry room enhance everyday functionality without compromising design. Large openings connect the interior to expansive outdoor spaces, creating an effortless extension of the home.
