YOUR OWN PRIVATE WATERFRONT OASIS: CAPTIVATING ESTATE LIVING. This extraordinary Katama Bay waterfront retreat blends timeless coastal architecture, refined interiors, and the natural beauty of Chappaquiddick in unforgettable fashion. Designed by noted architect Patrick Ahearn, this magnificent residence is privately sited at the end of a winding drive on 16.4 acres, offering more than 7,200 square feet of beautifully appointed living space created for the ultimate luxury: treasured time with family and friends. Inside, the home exudes warmth and sophistication with four wood-burning fireplaces, handsome hardwood and painted floors, custom millwork, built-ins, inviting gathering spaces, and sweeping views of Katama Bay from nearly every room. A rooftop widow's walk crowns the home, offering breathtaking 360-degree vistas across the bay, dunes, tidal ponds, and surrounding grasslands. One of the home's most captivating features is the expansive screened and covered porch, extending nearly the full length of the house and overlooking the sparkling waters of Katama Bay. It is an idyllic setting for relaxed summer dinners, quiet afternoons with a book, lively games, or simply taking in the brilliant evening sunsets. With more than 320 feet of Katama Bay frontage, the property invites a true waterfront lifestyle, with exceptional opportunities for sailing, boating, paddleboarding, fishing, and clamming. Beyond the shoreline, Chappaquiddick offers a rare sense of peace and privacy, with miles of unspoiled beaches, nature trails, sand dunes, tidal ponds, and protected habitats to explore. An attached three-bay garage provides ample storage for an island car, watercraft, bicycles, beach gear, fishing equipment, and every essential for life by the water. Offered turnkey, the home includes hand-selected furnishings and accessories by interior designer Jon Hattaway of MJ Berries Design in Boston, whose vibrant colors, curated objects, and artful details bring character and delight to every room. Enjoy the property exactly as it is, or make it your own and create a signature coastal haven. At once elegant, welcoming, and deeply connected to its extraordinary setting, this private Katama Bay retreat is designed for effortless waterfront living.
