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. Both the front and rear yards feature substantial, level lawn areas—an increasingly rare offering in Mill Valley—providing ample room for entertaining, recreation, or simply enjoying the surrounding setting.

A standout feature of the property is the attached ADU above the garage, offering a fully independent living space ideal for guests, extended family, home office or additional income potential. This added versatility elevates the property beyond a traditional single-family home.

Designed for both comfort and longevity, 308 Marin Avenue delivers the ease of new construction with a refined farmhouse aesthetic, all within close proximity to Mill Valley’s vibrant downtown, award-winning schools, and world-class outdoor access.
