Located in a secluded enclave in Water Mill, this one-of-a-kind modern estate spans 16 acres at the highest elevation on the East End, offering panoramic views of farmland, polo fields, and the Atlantic Ocean. Designed by the acclaimed 1100 Architect team, the compound includes three separate residences, each on its own separate parcel, totaling 9 bedrooms and 10 bathrooms. The SkyBox Main House has 4 bedroom suites with striking modern architecture across two floors and a foyer level. Features include a refined 1,000-bottle wine room with a built-in tasting table, along with a laundry area and a bright, windowed flex space ideal for a home gym or potential additional bedroom. On the bedroom level, you’ll find a generous primary suite complete with a private dressing area and a spa-style steam shower. A sunlit landing opens to a striking gallery lounge/media den, flanked by two large ensuite guest bedrooms, currently utilized as art studios. This level is enclosed by a cleverly designed fiberglass screen that beautifully diffuses natural light throughout the space. A floating staircase leads to the upper living area—an architectural showpiece with floor-to-ceiling windows and motorized sun shades, offering treetop, sky, and water views in every direction. At the heart of this level is a dramatic central atrium, connecting a cozy conversation den, the Sculpture Great Room, and an artist studio that also functions as a dining room. The open kitchen features a built-in breakfast nook, custom cabinetry, and high-end appliances. At the top, a spiral atrium staircase brings you to the crown jewel of the home: the rooftop deck, offering breathtaking panoramic ocean views, a built-in wet bar, and 560 square feet of space for entertaining. The Modern Treehouse is a separate 3-bedroom guest house with eat-in kitchen, treetop views, and a finished studio/guest suite with full bath and private entrance, positioned on its own 3-acre parcel with potential for expansion. Lastly, there is a second accessory structure which is The Glass House, a sleek 1-bedroom glass-walled residence with kitchenette and private patio, also on its own shy 3-acre parcel with expansion potential. The compound also features a 15×50 heated Gunite infinity pool, pool pavilion with outdoor kitchen, cabana lounge, full bath, and fire pit, as well as a Har-Tru tennis court with courtside lounge and a freestanding two-car garage. Offering privacy, architectural distinction, and potential for future development, this estate is a rare opportunity to own a modern masterpiece in the heart of the Hamptons.
