Perched along the pristine shoreline of Sag Harbor Bay, this newly constructed waterfront estate offers one of the most extraordinary settings in the Hamptons. Situated on 1.7 private acres surrounded by a protected tidal estuary, the property delivers uninterrupted panoramic water views, exceptional privacy, and a seamless connection to nature. Spanning over 6,000+/- square feet across three finished levels with elevator access throughout, the residence features six beautifully appointed bedroom suites designed to maximize light, space, and the breathtaking surroundings. The main level primary suite is a true retreat, complete with floor to ceiling glass walls and a private covered terrace showcasing spectacular sunrise to sunset vistas with no neighboring homes in sight. Three additional guest suites are also located on this level. The upper level reveals the home's most dramatic living spaces, where soaring open concept interiors are framed by expansive walls of glass and oversized sliding doors that create a seamless indoor-outdoor lifestyle experience. The living room, dining area, and gourmet chef's kitchen all overlook the stunning bayfront scenery. Thoughtfully curated finishes include exquisite Italian stonework selected to complement the natural landscape, anchored by a statement Officine Gullo range. Designed for both relaxation and entertaining, the outdoor living spaces feature expansive terraces, an elevated pool, sun drenched lounging areas, and covered waterfront dining. The garden level offers two additional family suites, a media and recreation lounge, and a waterfront fitness studio complete with a six person barrel sauna and cold plunge. Beautifully landscaped grounds lead to a private walkway and bayfront beach, where a secluded picnic area creates the perfect setting for peaceful waterfront afternoons. Rarely does a property combine architectural sophistication, resort level amenities, and such an unparalleled natural setting in one offering. A truly exceptional Hamptons waterfront estate.
