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.

Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
