A rare opportunity in southern New Hampshire, two fully self-contained living spaces under one roof, on one deed, with one set of taxes. The main residence (5R) is new construction completed in 2025, while the attached ADU (5L) has been rebuilt from the studs up to live like new. Each unit offers its own private entrance, full kitchen, bathrooms, and independent living space. This is not a traditional multi-family, but a premium single-family with a turnkey accessory dwelling built in. 5R features an open-concept first floor with hardwood throughout and a designer kitchen with white shaker cabinetry, granite countertops, stone backsplash, and double wall oven, opening to a bright living and dining area with slider to the rear deck. Upstairs, cathedral ceilings enhance the primary suite with a spa-like ensuite including a reclaimed wood double vanity, farmhouse sinks, Calacatta marble surround, walk-in shower, and soaking tub, plus two additional bedrooms and a full bath. High-end systems include Rinnai tankless hot water, zoned hydronic heat, spray foam insulation, multi-zone mini-splits, and a Generac transfer switch for generator readiness. 5L lives like new construction with wide plank flooring, cream walls, and a full kitchen featuring two-tone shaker cabinetry, granite counters, French door refrigerator, and in-unit stacked washer/dryer. Two bedrooms, including a spacious primary, a second with built-in closet organizer, and a stylish bath with black marble tile and subway surround. A bright living area, private courtyard, and dedicated entrance make it ideal for extended family, guests, or rental use.
