Absolutely turn key and fully restored iconic modernism of world-renowned, award-winning architect Charles Gwathmey, designer of the Guggenheim Museum addition, this exquisitely rendered and pristine 8000+/- sq. ft. 7 bedroom, 11.5 bath, masterpiece displays Gwathmey's genius in use of space, light, materials, and flow that blur the line between architecture and art while maintaining the clean, simple lines for which Gwathmey is known. Both the sweeping view over 2.5+/- acres of manicured grounds and the floor-to-ceiling fireplace in the double-height living room form the centerpiece of the room. A glass block wall runs the length of the interior courtyard and hallway from which a series of en-suite guest rooms are found. The master suite with his and hers baths and dressing rooms takes full advantage of the light for which the Hamptons is known and puts the view center stage. Curved walls hug the formal dining room with a soaring ceiling and spiral staircase leading to the second floor office with balcony and panoramic ocean views. Gourmet kitchen with Bulthaup cabinetry, 2 Subzeros, and the finest finishes opens to a dining area and great room that give to views of the courtyard. The courtyard also provides the view from the library. The lower level features a game room, media room, gym, and 2 wine cellars. The finest materials were used throughout this House & Garden published home, including custom mahogany millwork, granite, marble, and block glass. The meticulous grounds designed by famed landscape designer Ed Hollander offer a heated gunite pool with spa, pool house with bath, all weather tennis, and deeded ocean access with immediate proximity to the ocean. Smart technology includes Lutron lighting, Crestron home automation, geo-thermal cooling, and a full security system. Five car heated garage.
