About this home

A remarkable waterfront setting meets exceptional craftsmanship on 1.55 acres along Cohasset’s Gulph River. Reimagined over two years as a forever home, this residence was comprehensively reconstructed by a respected local builder and expanded from the original foundation up, transforming a classic Cape into an elegant French Colonial while preserving meaningful pieces of its history. More than 5,700 SF of living space is framed by panoramic river and marsh views with walls of glass presenting spectacular sunrises and serene sunsets. The home's slopeside position creates an elevated setting overlooking the river and marsh while offering a private backyard oasis. Inside the home, wide-plank hickory floors, high-efficiency Andersen windows and doors, closed-cell insulation, three-zone HVAC and a high-performance hot water system reflect the same attention to quality found throughout. At the center of the home, the chef’s gourmet kitchen pairs professional-grade Viking appliances with leathered Brazilian quartzite, custom cabinetry, imported Moroccan tile and a commercial-grade hood trimmed in reclaimed 1800s barn beams. Open living and dining spaces flow to the waterside deck, while the living room’s gas fireplace features a handcrafted mantel of the original hand-sawn barn beam. The primary suite is a private retreat with a balcony, a walk-in closet, and a distinctive spa bath with a custom Turkish-spindle vanity, an oversized clawfoot soaking tub, and a Tadelakt-finished shower. Three additional bedrooms and two more full baths complete the second floor. The finished walkout lower level, with two sets of French doors, water views, full bath, and polished concrete floors, offers flexible space for a gym, recreation, guests and more. Outside, an expansive lawn offering endless possibilities leads toward the river with timeless views across the estuary and direct access to the water. A renovated barn adds exceptional versatility, including a heated and cooled second floor ideal for an office or studio. MoistureShield CoolDeck composite decking, a backup generator, and thoughtful efficiency upgrades complete this extraordinary Cohasset property, just a short walk to the Village, commuter rail, restaurants, and harbor.
