Welcome to "My Oyster" a custom-built 2-bedroom, three-bath guesthouse with cherry cabinets, maple and cherry trim, wide pine and hardwood floors, wainscoting, and crown molding, creating a luxurious ambiance of warmth and tranquility. A Dutch oven satisfies culinary desires, and the great room next to the two-car garage can serve as an office, gym, or game room. High on a bluff, My Oyster's decks offer a 180° view of Oyster Pond, Stetsons Cove, and the Oyster River out to Nantucket Sound. This historic 1.4-acre waterfront estate, once part of Chatham Bars Inn's farm, has been cherished by the same family for over 70 years. The 60,000-square-foot lot supports the potential for a custom four-bedroom dream home, tennis court, or pool. A Post and Beam barn with water and electricity makes a great workshop or man cave. Accessible via a scenic driveway, the property offers tranquility, privacy, and timeless charm. Seller welcomes offers with requests for buyer concessions.
