Rooted in Duxburys maritime heritage yet designed for modern coastal living, this exceptional 5,073-square-foot estate pairs architectural elegance with resort-style amenities. Sited on 1.63 acres just two doors from the Bay Farm Trails, the five-bedroom, six-bath residence offers sweeping views of Duxbury Bay and the waters beyond. The main house blends timeless colonial lines with refined interiors--an expansive chefs kitchen with wood-planked ceiling and central island, formal dining room, flexible office, and light-filled living room opening to decks and lawns. The serene primary suite occupies its own private wing with water views, spa-like bath, and lounge, while the third-floor observatory captures panoramic sunrises over the harbor. A fully finished lower level hosts gym, media, and recreation space. Outside, a separate guest/pool house overlooks a heated bluestone-surfaced pool, integrated spa, and fire-pit terrace leading to a private boardwalk and waterfront access. Complete with a three-car garage and lush landscaping, this is the rare Duxbury offering that unites heritage, scale, and turnkey coastal luxury--minutes from Routes 3/3A, the MBTA line, and town center.
