Bordered by more than 4,000 acres of protected Nehantic State Forest and Lyme Land Trust land, this extraordinary 21-acre property offers a rare opportunity to live in harmony with nature with low-impact infrastructure. This certified Green Home seamlessly blends timeless architecture and forward-thinking technology. Geothermal heating and cooling and solar-powered electricity create an environmentally responsible lifestyle while dramatically reducing operating costs. Inside, an open concept design affords effortless living and entertaining space filled with natural light. The main level is warmed by hydronic underfloor heating including a sought-after first-floor primary bedroom. Three additional bedrooms with hardwoods share access to a large walk-out storage area, providing flexible expansion space. A lower level with extraordinary ceiling height showcases top-tier mechanical systems and direct access to the third garage bay. Beyond the home, miles of forest creates a sense of seclusion and serenity, yet the property remains exceptionally accessible. Located just a mile north of Hamburg Cove, residents enjoy access to marinas and kayaking. Fox Hopyard Golf is five minutes north, and Saybrook Station-with rail service to New York/Boston-is 12 minutes from the property. A place where conservation, sustainability and timeless beauty converge, the property represents a rare offering in one of Connecticut's most treasured natural landscapes.
