About This Property

Beautifully situated directly on Stony Brook Harbor, this exceptional waterfront residence offers captivating water views, remarkable privacy and an extraordinary level of custom craftsmanship. Completed in 2024 with no expense spared, the home is a study in sophisticated design, exceptional materials and meticulous execution. With walls of glass framing the harbor and interiors distinguished by one remarkable detail after another, it has the presence and polish of a home that could have been lifted from the pages of Architectural Digest.

Every element feels considered. Soaring ceilings and six-inch-wide white oak flooring establish a sense of warmth and scale, complemented by exceptional millwork, custom solid-wood doors, bespoke cabinetry and authentic 1800s barn beams incorporated as architectural accents. Walls of Andersen casement windows and transoms fill the interiors with natural light, while distinctive ceiling treatments and carefully selected finishes give each room its own character.

A sculptural curved staircase creates one of the home's most memorable architectural moments. Beautifully crafted in solid white oak, its graceful form and open design feel more like a piece of custom architecture than a traditional staircase, bringing another layer of artistry to the interior.

The custom chef's kitchen is a statement in both design and craftsmanship, pairing beautifully crafted white cabinetry and designer hardware with dramatic white marble waterfall countertops, a six-burner Viking range and oven, paneled Sub-Zero refrigeration and top-tier appliances. Authentic antique barn beams introduce warmth and architectural character, while radiant-heated floors, an impressive center island and a window-wrapped dining area with French sliding doors opening to the bluestone patio create an exceptional space for both entertaining and everyday living.

The great room takes full advantage of its waterfront setting, with walls of windows framing Stony Brook Harbor, while a gas fireplace, beautifully detailed solid white oak ceilings and custom millwork bring warmth and architectural depth to the space.

The entire second floor is devoted to the primary suite, creating an exceptionally private retreat with a custom walk-in closet and spa-like bath beautifully appointed in authentic white marble, featuring a soaking tub, oversized marble shower with built-in bench, radiant-heated floors and a coordinating marble vanity. A separate waterfront sitting room opens through French doors to an expansive Ipe deck overlooking Stony Brook Harbor-a serene place for morning coffee or unwinding as the light changes across the water. A separate private gym completes this remarkable level, creating a retreat devoted entirely to comfort, wellness and privacy.

Additional bedrooms and baths continue the home's bespoke approach, with distinctive materials and custom details giving each space its own character. Even the practical spaces have been thoughtfully considered, including a mudroom and striking custom lower-level entry with wood-paneled walls, integrated lighting and built-in storage.

Outside, lush lawns, mature trees, bluestone patios and thoughtfully designed landscaping complement the home and its waterfront surroundings. A full basement, 2.5-car garage, gas heat, whole-house generator, integrated speaker and security systems, and smart-home features complete the residence.

Rarely does a home bring together this caliber of craftsmanship, architectural character and waterfront beauty so completely. Created without compromise and entirely one of a kind, this is a residence as extraordinary as its setting-where the beauty of Stony Brook Harbor is ever-present and spectacular sunsets over the water provide an unforgettable backdrop at the end of each day.
