At $1.385 million, this is simply the best valued new construction in all of Southampton Township, created by Southampton Building Corp, one of Long Island's most prominent master builders. A veritable boater and water lover's paradise, this new, fully finished, and furnished residence is located in an ultra-luxury, four-home cul-de-sac development on the renowned South Bay Avenue in Eastport's most valuable and prestigious enclave, near Southampton's Seatuck Cove Bay. Enjoy the marina, boat launch, and waterfront dining just down the block, or relax at home in your 20x40 heated saltwater pool! Move-in ready: the CO is in hand for both the house and the pool, so you don't have to wait to live the Hamptons and brand-new construction dream! Alternatively, the home can generate substantial summer rental income for its proud owner, as it is conveniently situated on the western edge of Southampton Township, close to transportation, beaches, parks, and a much shorter commute to New York City. The home offers over 3500 sq. ft. of impeccably finished living space across three levels, including four bedrooms and three and a half baths, featuring two luxurious bedroom suites, one on each floor, providing flexibility for guests or multigenerational living. Designer finishes abound, from wide-plank white oak floors and custom cabinetry to Italian tile bathrooms and handcrafted built-ins. The kitchen dazzles with a 2-inch mitered Silestone island, and the smart home hub seamlessly and remotely controls the alarm, doorbell camera, and temperature. This home would cost approximately $2 million to rebuild today due to recent increases in tariffs on imported construction materials. This is a rare opportunity to own a fully completed, fully furnished new construction home with excellent investment metrics, below replacement cost, and ready for immediate occupancy with no compromises and no delays!
