Set on a private 5-acre peninsula with 740 feet of deepwater frontage on the Back River, this masterfully crafted coastal estate offers an exceptional Maine waterfront retreat. Substantially updated by the current owners, enhancements include a stunning new kitchen, updated bathrooms, new decking, fresh paint, refined flooring, and revitalized landscaping. Blending timeless post and beam craftsmanship with modern luxury, the residence offers 6 bedrooms, 5.5 bathrooms, and over 5,000 square feet of finished living space across three levels. From the moment you enter, the home captivates with soaring cathedral ceilings, exposed timbers, skylights, and walls of glass framing beautiful water views. The dramatic great room is anchored by a floor-to-ceiling fieldstone fireplace and custom wide-pine floors with an inlaid nautical compass rose. The newly renovated chef's kitchen features premium finishes, custom cabinetry, a center island, and an adjoining dining area. Multiple sets of French doors open to an expansive screened porch and open-air decks overlooking the river, ideal for morning coffee, summer dinners, or sunset cocktails. The main level features a private primary suite with its own fireplace, spa-like bath, and direct access to the screened porch. Upstairs, multiple guest bedrooms, a den, and an airy loft overlooking the great room provide flexible accommodations. The fully finished daylight walkout lower level adds an expansive family and game room, additional guest suites, and direct access to the outdoors. Outside, a private path leads to the deepwater dock, float, and two private moorings, providing direct boating access to the Sheepscot River and open ocean. Complete with an attached two-car garage, custom laundry room, whole-house automatic generator, and peaceful end-of-lane privacy, this turnkey coastal estate is just minutes from Boothbay Harbor and the renowned Country Club, and just over an hour from Portland International Jetport.
