About this home

First time to market, this designer-created waterfront estate on prestigious Rampasture Point captures the essence of Hamptons coastal living with breathtaking views of Tiana Bay and a private beach. Completely reimagined inside and out, this 4-bedroom, 3.5-bath smart home showcases exceptional craftsmanship, sophisticated finishes, and seamless indoor-outdoor living. A dramatic oversized pivot entry door opens to soaring ceilings, walls of glass, wide-plank white oak floors, custom millwork, Phillip Jeffries designer wallcoverings, statement lighting, and panoramic waterfront views. The chef’s kitchen features custom inset cabinetry, honed quartz countertops, a handcrafted range hood, Thermador appliances, and a designer coffee bar, flowing effortlessly into the dining and living spaces anchored by a natural-gas fireplace. The luxurious primary suite offers vaulted ceilings, designer lighting, a private coffee bar, and a waterfront balcony overlooking Tiana Bay. The spa-inspired primary bath features a freestanding soaking tub positioned beside a picture window with open-bay views. Motorized shades and smart-home technology provide effortless modern living, while multiple beverage stations and two temperature-controlled wine refrigerators enhance entertaining. The designer-created outdoor living space is an extension of the home, featuring expansive waterfront decking, a fully equipped outdoor kitchen, elegant dining and lounge areas, and a private gazebo overlooking the bay. A private beach provides direct access to kayaking, paddleboarding, boating, swimming, and shoreline walks, room for a pool. A whole-house generator provides year-round peace of mind, with room for a pool to further enhance the resort-style setting. Minutes from the sandy white beaches of Dune Road, premier marinas, waterfront dining, shopping, and the best of the Hamptons lifestyle, this is a rare opportunity to own a truly exceptional designer waterfront estate.
