Offering exceptional flexibility for multigenerational living, extended family, guests, or investment use, this extraordinary post and beam property combines historic character with versatile living spaces and a quintessential Maine setting. Originally built as a mill circa 1860+/-, the home has been thoughtfully renovated while preserving its character. The lower-level ADU is a standout feature, offering a private entrance, full kitchen, living and dining areas, two bedrooms, laundry, and river views. Whether used for family, guests, a separate living arrangement, or as a rental opportunity, this additional living space provides flexibility that is increasingly difficult to find. The main residence features expansive living and dining areas with soaring cathedral ceilings, exposed beams, skylights, wide-plank wood floors, and a dramatic chandelier. A mounted projection screen makes the most of the impressive ceiling height, creating an inviting gathering space. The upper-level primary suite offers a private, loft-like retreat overlooking the living area, while the kitchen blends rustic character with modern style through custom green-blue cabinetry, butcher block countertops, a large center island, and herringbone-patterned flooring. Set within a park-like landscape, the property offers a peaceful connection to the outdoors with the Piscataqua River. Enjoy coffee on the porch, entertain on the riverside deck, or unwind in the hot tub while taking in the natural surroundings. Numerous improvements include new windows and doors, added insulation, updated electrical, renovated bathrooms, custom cabinetry, a covered porch addition, new garage, whole-house Generac generator, hot tub, and a new leach field supporting the ADU. Whether envisioned as a multigenerational home, a private residence with separate guest accommodations, or an investment property with rental potential, this unique offering provides an opportunity to own a piece of Maine history.
