Privately nestled behind a grand electric gate on 1.42 acres of professionally landscaped grounds with mature specimen trees, this 7,355 SF modern estate is a rare offering in the Hamptons-combining architectural sophistication, resort-caliber amenities, and serene natural beauty. Originally a cottage, the home was completely transformed and expanded in 2017 by acclaimed Swiss architect Martin Scheffer (Zurich) into a forward-thinking, energy-efficient residence constructed of steel, foam, and concrete, finished with soft stucco and a sleek standing seam roof. Surrounded by mature specimen trees and manicured gardens, the property directly backs up to a tranquil nature preserve, enhancing its unmatched sense of peace and seclusion. Bathed in natural light, the home features expansive wall-to-wall sliding glass doors, skylights, and oversized windows throughout-blurring the line between indoors and out and creating a peaceful, spa-like ambiance from every room. Every view is framed by lush gardens, creating a true sense of retreat. Beyond the foyer, you step into a spacious formal living room with full glass sliders offering serene views of the grounds. Beyond lies the dramatic great room with soaring tongue-and-groove cedar ceilings, encompassing a custom Italian-designed kitchen with dual islands and Miele appliances, a large dining area, and an inviting den with fireplace-ideal for entertaining and gathering. Travertine flooring imported from Italy flows seamlessly from interior spaces to outdoor patios, reinforcing the home's indoor-outdoor lifestyle. A stunning glass-enclosed sunroom houses a heated gunite pool and spa for year-round relaxation, evoking the feeling of a private wellness resort. The home offers five bedrooms, a dedicated home office with fireplace, and a fully finished lower level with a laundry room,large cedar closet, sauna and area for a gym or den. Upstairs, a very spacious artist's studio with a half bath opens to a private second-floor terrace, perfect for a peaceful escape - which connects to the backyard via a custom spiral staircase. Outdoors, enjoy an all-weather tennis court, inground pool and jacuzzi, outdoor shower, herb garden, and greenhouse-surrounded by complete privacy and natural beauty. This one-of-a-kind Hamptons estate offers a rare blend of bold architecture, light-filled luxury, and year-round resort living in the most serene setting.
