Just completed, this incredible project by Michael Frank Building is set on .48 acres in Amagansett South, offering a private, resort-like retreat with luxurious finishes and every modern amenity thoughtfully integrated.. Due to updated zoning regulations, homes of this scale can no longer be built in Amagansett Lanes. This estate spans 8,000± sq. ft. across three full levels of living, with 7 bedrooms, 9 bathrooms, and an expansive outdoor program that includes a saltwater pool, spa, and fully equipped pool house. The main level features an open-concept kitchen with Calacatta Borghini marble countertops, top-of-the-line Wolf and Sub-Zero appliances, and an inviting eat-in dining area. Flowing seamlessly into the great room, soaring 15-foot ceilings and a striking fireplace create an atmosphere of grandeur. This level also includes a gracious junior primary suite, a spacious den, a mudroom/laundry room, a powder room, and a versatile office or den that can easily transform into a formal dining space. Upstairs, the primary suite is a true sanctuary, complete with vaulted white oak ceilings, a spa-like bathroom, a walk-in closet, and a private covered rooftop deck overlooking the backyard. Three additional guest suites, each with its own en-suite bath, complete this floor. The finished lower level is designed for entertainment and relaxation, featuring a large recreation room with a wet bar, a movie theater/lounge, a gym with an infrared sauna, a powder room, and two additional bedrooms sharing a full bath. Step outside to an entertainer's paradise, where a 20'x40' heated gunite saltwater pool with an 8'x8' spa, sun ledge, and a 200± sq. ft. pool house with a bar, seating area, full bath, and cedar outdoor shower set the stage for luxurious outdoor living. The Marmiro Turkish marble patio extends to an outdoor kitchen ideal for al fresco dining, while the covered lounge-complete with a TV and gas fireplace-provides the perfect place to unwind. Additional features include a 48kW full-house backup generator and a 500± sq. ft. heated two-car garage with an EV charger for added convenience. Located less than a mile from Atlantic Beach and just moments from Amagansett Village, this remarkable home embodies the essence of "Lane's Living," with easy access to both Montauk and East Hampton.
