58 Oyster Bluff Perched high above Oyster Pond, this generational estate-first known as ''The Beach Plum House'' and later as ''Adsamore''-is one of Chatham's rarest offerings. Set on a remarkable .93-acre parcel with expansive frontage, it offers sweeping views of town and Oyster Pond, a lifestyle at once connected and secluded. Originally built in Wellfleet as the Captain Holbrook House, the home has been lovingly preserved and expanded over time while being modernized for hosting and gathering. The seven bedrooms include a private first-floor primary suite with walk-in closet and ensuite bath, while a Good Morning staircase, adorned with a hand-painted Chatham mural, leads to the upper level bedrooms. Historic character endures throughout: the wood room with elements from the Plymouth Cordage Co. ropewalk (circa 1824), hand-hewn structural beams, herringbone brick floors, central hearths, and authentic built-ins. Outside, brick patios, mature sycamore trees, granite steps, and rock walls frame rolling lawns that meet the water's edge, where a private catwalk and moorings await. Spacious yet intimate, this is a true legacy property-an irreplaceable waterfront setting ready for its next steward.
