Just completed, this fifth Lanes project by Michael Frank Building is nestled on half an acre in Amagansett south, providing a private, resort-like experience. The expansive brand new residence spans three levels, offering seven bedrooms and nine bathrooms (seven full and two half), with every amenity thoughtfully included among high-end finishes throughout. The main floor boasts an open-concept kitchen with Calcutta Borghini marble counters among Wolf and Subzero appliances with an eat-in dining area that flows seamlessly into the great room, where soaring 15-foot ceilings and a stunning fireplace create a sense of grandeur. This level also features a gracious junior primary suite, a spacious den, a mudroom/laundry room, powder room, and an office or den that can be transformed into a formal dining room if desired. Upstairs, the primary suite stands as a luxurious retreat with vaulted white oak ceilings, a spacious bathroom, a walk-in closet, and a private covered rooftop deck overlooking the backyard. Complementing the primary suite are three additional guest bedrooms, each with its own en-suite bathroom. The finished lower level offers ample entertainment options, including a large recreational room with wet bar, a movie theater/lounge, a gym with an infrared sauna, a powder room, and two additional bedrooms that share a full bathroom. Outside, indulge in the heated 20'x40' gunite saltwater pool with an inset 8'x8' spa, sun ledge, and a 200± sq. ft. pool house equipped with a bar, sitting area, full bathroom, and cedar outdoor shower. Perfect for entertaining, the backyard includes an outdoor kitchen set on the Marmiro Turkish marble patio perfect for al fresco dining, and a covered outdoor lounge complete with a TV and gas fireplace. A 48kw full-house backup generator and a 500± sq. ft. heated 2-car garage with an EV charger ensure convenience and peace of mind. Embracing the essence of "Lane's Living," this remarkable property is less than a mile from Atlantic Beach, close to Amagansett Village, and within easy reach of both Montauk and East Hampton.
