About This Home

Rarely does a property of this caliber become available in one of Harvard's most sought-after locations. Set on an extraordinary 6.96 acres of pristine level fields and picturesque trails, this remarkable estate offers exceptional privacy and serenity while remaining just minutes from Routes 2 and I-495. Close to Harvard Park and conservation land with trail access, the setting is a nature lover's paradise where peace, tranquility, and endless recreational opportunities await. At the heart of the property is an 1860s Antique Farmhouse that seamlessly blends timeless New England character with today's modern comforts. Historic charm is showcased through classic architectural details while thoughtful updates provide the convenience and efficiency expected by today's buyers. The home offers three generously sized bedrooms, two full baths on the second floor, and a convenient first-floor half bath. Designed for exceptional efficiency and year-round comfort, the property features a geothermal heating and cooling system that leverages the power produced by the photovoltaic solar panels, and solar thermal panels for hot water significantly reducing energy costs through sustainable living. The impressive collection of outbuildings creates endless possibilities. A remarkable three-story historic 24'x36' barn with expansive hayloft and abundant storage serves as the centerpiece for agricultural, equestrian, or hobbyist pursuits. Two separate detached three-car garages provide exceptional vehicle and equipment storage, including one with a beautifully finished one-bedroom ADU above, ideal for guests, multigenerational living, rental income, or a home office. Completing the estate is a substantial 30' x 60' barn structure, perfectly suited for farm equipment, contractor operations, collector automobiles, RV storage, or workshop space. Outdoor living is equally impressive with a stunning in-ground gunite pool overlooking the expansive grounds. Whether you're seeking an equestrian estate, property to farm and raise animals, family compound or private country retreat, this exceptional property offers limitless potential.
