About This Home
In the heart of Bridgehampton's famed horse country, this five-acre estate offers style, quality, and privacy at an exceptional level. Designed by the esteemed architects Barnes Coy, the residence blends timeless Hamptons character with refined modern craftsmanship. A cedar shingle exterior sets the tone for interiors appointed with limestone and oak floors, solid five-panel mahogany doors, and four fireplaces, including one outdoors. Rounded walls, detailed moldings, bluestone patios, and copper leaders and gutters all speak to the richness and attention to detail seldom found in new construction. Comfort is ensured year-round by a five-zone heating and cooling system. The circular entry foyer opens into a sun-filled great room with soaring 24-foot ceilings framed by French doors and transom windows. The first floor includes a grand dining/living hall, gourmet chef's kitchen, mahogany library, guest bedroom, one and a half baths, laundry, and pantry. Upstairs, the primary suite is complete with a spa bath and steam shower, joined by two additional bedrooms and baths. The lower level offers a wine cellar, gym/office/guest suite, a full bath with steam shower, and abundant storage. A separate pool house features a kitchenette, bath with steam shower, and lounge area, while the two-car carriage house includes an office/apartment. Outdoor living is defined by expansive bluestone terraces and a striking 60-foot semi-circular heated gunite pool, set against manicured lawns, flowering gardens, and panoramic treetop vistas. This Bridgehampton estate combines architectural distinction with pastoral serenity-an extraordinary offering in one of the Hamptons' most sought-after settings.
