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.

Martha's Vineyard, located between Vineyard Sound and Nantucket Sound, is a coastal and rural West Tisbury neighborhood with wooded back roads and broad farm fields. The neighborhood’s character concentrates around the West Tisbury Village Center at State Road and Edgartown–West Tisbury Road, where the library lawn, small shops, and a low-key town-green rhythm set the pace. Architecture leans to shingled cottages, classic capes, and working farm outbuildings tucked behind stone walls. The Polly Hill Arboretum adds curated woodland paths and rare plantings to the island’s natural palette. The Grange Hall anchors a calendar of community gatherings, while Alley’s General Store keeps the everyday essentials distinctly local. Long Point Wildlife Refuge and nearby beaches frame a lifestyle shaped by trails, ponds, and salt air.
