45 Thatcher Hill Rd, Marlborough, NH 03455

A rare opportunity: this extraordinary 1794 Colonial and its four-story barn, set on 30+ acres in the Monadnock region, form one of southern NH's most significant historic properties, a unique blend of period character, land, and privacy, with Mt. Monadnock views. Thirteen rooms across 6,200 sq feet, plus 5 bedrooms (with the option for 4 more) and 6 baths: space for family, homestead, multigenerational living, or reinvention as a venue, inn, or business. Four masonry fireplaces, granite foundation, wide-board floors, and exposed beams carry forward 18th-century craftsmanship. An expansive back deck, covered porch, and balcony extend outdoor living. The barn is the showstopper: a one-of-a-kind, 7,400 sq ft structure built in 1894 with timber from Mt. Monadnock, includes four soaring floors plus a cupola. Its granite foundation, quarried by the original owner, joins a massive granite wall enclosing the paddock. Original horse stalls, a woodworking shop, and finished studio space fill the floors, upgraded with septic and water, in a once-in-a-lifetime chance to preserve barn history. The mature maple-lined driveway leads in from a state route and a local road. 30+ acres divide between open, flat fields and mature woodland, laced with walking paths, a goldfish pond, antique silo, glass greenhouse and raised beds.
