Horizon House sits atop one of Chilmark's most private and elevated parcels, offering protected and sweeping views of the Atlantic Ocean. Framed by meadow, mature trees, stone walls, and native terrain, the estate holds an extraordinary connection to both land and sea. The 4+ bedroom main house has been thoughtfully reimagined for today's buyer, designed and built by a team of leading architects and artisans. Grounded in its natural setting, the architecture features dramatic design elements and walls of glass to connect seamlessly with the idyllic landscape. An infinity-edge pool overlooks the pastoral ocean horizon that defines Chilmark, while a screened porch and large outdoor living areas extend the home into its surroundings. A separate 2-bedroom guest house and additional 5.6 acre lot provide flexibility for expansion and subdivision, while a private path to Chilmark Pond allows for deeded access to South Beach. Horizon House is a pleasure to show, by appointment only.
