About This Home

Set on a beautifully landscaped .58-acre property in the heart of the Hamptons, this stunning 4400 sqft new construction home at East Hampton offers 7 bedrooms and 5.5 baths across three impeccably designed levels of luxury living. Ideally located just minutes from both Sag Harbor Village and downtown East Hampton, the home blends sophisticated design with effortless indoor-outdoor living.
The sun-drenched main level features an expansive great room with a gas fireplace, seamlessly flowing into a chef's kitchen outfitted with Wolf cooktop and oven, wine refrigerator, microwave, and an oversized island perfect for entertaining. A first-floor ensuite bedroom provides ideal accommodations for guests, while a spacious laundry room and stylish powder room complete the main floor. Upstairs, the spa-inspired primary suite offers a serene retreat with a luxurious bath and private ambiance. An additional ensuite bedroom and two generously sized guest bedrooms connected by a Jack-and-Jill bath complete the second level. The finished lower level is designed for relaxation and recreation, featuring two additional bedrooms, a full bath, and a large recreation area ideal for media, fitness, or game space. Outside, the resort-style backyard is anchored by a sparkling gunite pool and an expansive covered patio designed for year-round enjoyment. An outdoor fireplace with space to mount a television creates the perfect setting for entertaining, relaxing, and enjoying Hamptons evenings in style.
