Some properties simply cannot be recreated. Set on more than 1.3 acres along historic Old King’s Highway, this distinctive four-bedroom antique offers a rare combination of Cape Cod character, a magnificent two-story barn, sandy frontage on Scargo Lake and a charming screened boathouse at the water’s edge. Thoughtfully updated over time, the home blends original details, two staircases, unexpected nooks and two long enclosed porches with a beautifully renovated kitchen featuring a bank of windows overlooking the grounds and lake beyond. Follow the gently sloping path through the trees to clear water, a sandy shoreline and sweeping views toward Scargo Tower. Swim, kayak, paddleboard, fish or enjoy quiet mornings beside the lake. The property has also served as a successful seasonal retreat, recently renting for approximately $5,500 per week. The home may continue to evolve, but the acreage, lakefront setting, antique barn and magical boathouse are nearly impossible to duplicate.
