The epitome of Hamptons luxury awaits at 1 Fiske Avenue, Westhampton Beach-a newly constructed 2023 estate designed with uncompromising craftsmanship and an eye for elevated coastal living. Set on 1.13 pristine acres south of the highway, this 5-bedroom, 5.5-bathroom masterpiece spans 5,550 square feet and offers sweeping views of Moriches Bay, just minutes from the charm and convenience of Westhampton Beach's Main Street. From the moment you enter the grand foyer, the home exudes thoughtful sophistication-showcasing 7" white oak flooring, solid core doors, custom closets, and Hunter Douglas window treatments throughout, including automated shades in the upstairs primary suite. The open-concept layout is anchored by a dramatic double-height living room with soaring 20-foot ceilings, a striking 42" gas fireplace, and stunning water views, all flowing seamlessly into the expansive backyard retreat. At the heart of the home is a show-stopping chef's kitchen, outfitted with top-of-the-line Sub-Zero and Wolf appliances, Caesarstone countertops, an oversized center island with seating for four, double dishwashers, warming drawer, and custom cabinetry. A walk-in pantry adds convenience and flair, equipped with a Wolf microwave drawer, XO wine refrigerator, and abundant storage. Also on the main level, a custom-built office offers a private workspace, while the first-floor junior primary suite enjoys tranquil views of the backyard, pool, and bay. Its spa-like bath features a 72" Pottery Barn double vanity, radiant heat floors, soaking tub, walk-in shower with rainfall shower head, and a custom-designed walk-in closet. A separate guest suite provides privacy down a quiet corridor. The mudroom with herringbone tile, custom cabinetry, full laundry, and pool bath completes the main floor. Upstairs, the second level stuns with views of Moriches Bay from nearly all rooms & offers three additional ensuite bedrooms, including the primary retreat. The primary suite opens to a private waterside balcony overlooking the lush grounds and includes oversized walk-in closet, a linen closet, and a luxurious bath adorned with Carrara marble, radiant heat floors, soaking tub, rainfall shower, and a second secluded balcony. A large bonus room with bay views and an additional laundry room add to the second level's thoughtful design. The outdoor living experience is nothing short of exceptional. A bluestone patio extends from the great room and mudroom to a 20' x 20' covered lounge complete with a fireplace and wall-mounted TV-ideal for entertaining. The fully equipped outdoor kitchen features a built-in Mont Alpi 6-burner BBQ with additional side burner, sink, beverage refrigerator, and storage.
