Property Description
Welcome to Treetops. A long private driveway passing a large pond sets the scene for this impressive hilltop retreat with 6,000 square feet across three levels and seasonal views of the Taconic Hills. Built with wood hewn from trees on the property, including the distinctive stairway, the home offers a huge open-plan main level ideal for gatherings, along with an indoor pool, hot tub, sauna and a dramatic two-story primary suite. Five bedrooms and five baths provide ample space for guests, with additional bedrooms on the upper and lower levels plus a family room downstairs. A second home may be built on a conserved, included, second parcel. Expansive decks, a three-car garage, sold fully furnished, and abutting the Appalachian Trail conservation lands complete the offering.
