The main house, dating to the 1700s, features 3 bedrooms and 2.5 baths, thoughtfully updated while preserving historic character throughout.

The main house, dating to the 1700s, features 3 bedrooms and 2.5 baths, thoughtfully updated while preserving historic character throughout. The private primary suite, accessed by its own staircase and complete with ensuite bath, was part of a later addition and provides a serene, modern retreat within the home. A tastefully extended kitchen enhances everyday livability while remaining true to the home's original scale and charm. Set farther from the road, the property's original historic barn was carefully dismantled, relocated, and reassembled into a striking and luxurious guest residence. This space includes a dramatic double-height great room, full bedroom, loft office, full bath, and kitchenette, along with a dedicated gym and two-car garage ideal for guests or an exceptional work-from-home lifestyle. The land spans both sides of a very quiet road, with a scenic stream meandering through the acreage across the way. A large stone pool, flat lawn, greenhouse, and professionally maintained grounds complete the estate setting. Held by the same family since the late 1960s, this move-in-ready compound is equally suited as a primary residence or refined country retreat an exceedingly rare offering of history, land, and flexibility.
