Before Cape Cod was a popular vacation destination, Helen J. Quinn, heiress to the Grand Union grocery chain, purchased almost 20 acres of land by the Centerville River. This property was Mrs. Quinn's personal estate, later dubbed 'Sandcastle' for its sandy English stucco exterior. Brilliantly designed for hosting family or guests, the layout is timeless, with formal spaces on the entry side of the property and sunny, glassed-in rooms the length of the water side, offering 180 degree views of Craigville River and Nantucket Sound. With 8 bedrooms in the main house and a full, 1400-sq ft apartment above the separate 4 bay carriage house, there's space for everyone. A deep water dock connected to ''the best boathouse on the river,'' makes day trips to Nantucket possible, or store a launch to zip across the river for sunbathing on the white sands of Long Beach. A brand new sea wall and elevated back yard were installed summer 2024.
