Set on nearly 28 private acres, this exceptional antique estate offers the rare opportunity of two distinct residences on one property, blending true 18th-century provenance with refined modern living. 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. A whole-house generator adds an additional layer of comfort and reliability. Set farther from the road, the property's original barn was carefully dismantled, relocated, and reassembled into a striking, luxurious guest residence. This space includes a dramatic double-height great room, full bedroom, loft office, full bath, and kitchenette, along with 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. In the same hands since the late 1960s, this move-in-ready compound is equally suited as primary residence or refined country retreat- a rare offering of history, land, and flexibility.
