About This Home

Quite simply, these are the most spectacular views you will find in the Hamptons. Recently constructed and stunning, this truly special waterfront modern home is set on 1.7 of the most spectacular acres you will find. Sited on the edge of Sag Harbor Bay and nestled in amongst a pristine tidal estuary, this light filled home features six bedroom suites set across 6000+/- square feet of finished living space on three levels, all serviced by elevator. A generous primary suite situated on the main level has floor to ceiling glass, and a private covered terrace with sweeping views from sunrise to sunset, and literally not a neighbor in sight. There are an additional three guest suites on this level as well. Upstairs, one is awed upon reaching the top of the stairs as the full scope of the vista comes into play. An open concept living room leads to the kitchen and dining areas, all surrounded by expansive fixed-glass and sliding doors that allow for true indoor-outdoor experiences with what are simply some of the most unique and special views on the East End. The gourmet chefs kitchen features spectacular Italian stone selected specifically to complement the natural scenic beauty outside, and is anchored by a luxurious Officine Gullo range. Outside, the expansive decks feature an elevated pool, open spaces for lounging in the sun, and magnificent covered dining. At garden level are two additional large family suites, a media and recreation space, and a waterfront gym with outdoor six-person barrel sauna and cold plunge. Exiting through the beautifully manicured lawn is a private walkway to the bayfront beach, perfect for a relaxing lunch at your own picnic table in the sand. There simply is no other offering like this to be found. Spectacular.
