Description
New listing offering a rare waterfront retreat — two adjacent waterfront properties being sold together as one conveyance — welcome to 18 & 20 Treehouse Way on Ayers Pond in Barrington. Together, these two single-family homes offer approximately 300’ of waterfront and a unique opportunity for year-round living, multigenerational use, or a cherished seasonal escape. Situated at the end of a private way, this peaceful compound offers privacy, nature, and flexibility. Designed with classic New England boathouse-inspired architecture, the homes embrace waterfront living with expansive glass, natural gathering spaces, and a seamless connection between indoors and out. 20 Treehouse Way is approximately 2,240± SF. The open floor plan is highlighted by a dramatic wall of windows framing water views and filling the home with natural light. Sliders lead out to the wraparound deck and screened porch — ideal for grilling, relaxing, and enjoying the pond. The kitchen flows into the gathering spaces and porch, while the private primary suite, additional bedrooms, and partially finished walkout lower level provide flexibility for guests, recreation, or work-from-home needs. Two lower-level sliders lead toward the dock. 18 Treehouse Way offers approximately 744± SF above a two-car garage. The open-concept layout makes it ideal as a guest house, in-law setup, studio, or private retreat. The dual-home configuration offers exceptional flexibility for extended family, guests, or potential income opportunities. With a private dock, abundant storage, and a backup generator, these lovingly maintained homes are in exceptional condition and truly move-in ready — this is the waterfront property you have been waiting for.
