A remarkable two-story barn, constructed in 1980 with reclaimed hand-hewn beams to reflect the home's original character, offers endless possibilities for entertaining, a studio, fitness space, home office, collector car storage, workshop, or more. Upstairs, the luxurious primary suite features a spa-inspired bath with soaking tub, separate shower, and dual vanity, complemented by two additional bedrooms and a versatile fourth room ideal as an office, den, or playroom.
