About This Home

As of August 2025

Tucked into a quiet cul-de-sac near Aaron River Reservoir, this charming 3-bed, 2-bath Gambrel sits on a beautifully landscaped half-acre in one of Cohasset’s most sought-after neighborhoods. A classic front porch welcomes you into the bright, eat-in kitchen with quartz counters, stainless appliances, and custom cabinetry. The well-designed layout features hardwood floors, a front living room with fireplace, dining room, and a cozy family room off the kitchen. Upstairs offers a spacious primary, two additional bedrooms, and a full bath. Enjoy a private backyard oasis with mature plantings, lush perennial gardens, and a peaceful patio. Includes a 2-car garage, generator, and ample storage. Just a short stroll to the soon-to-open Beechwood General, JJ’s Dairy Hut, ballpark, and playground. Minutes to Cohasset Village, Sandy Beach, commuter rail, and the harbor.
