This timeless estate, situated in an exclusive private association moments from town, masterfully blends turn-of-the-century grandeur with 21st-century luxury. The main house was extensively renovated and expanded in 2006 by award-winning architects Austin Patterson Disston. It showcases grand-scale rooms, soaring ceilings, and impeccable millwork. In 2016 the current owners made it their own by adding a wine cellar and renovating the primary suite to the same outstanding standards. The main house features six ensuite bedrooms and 7.3 baths. The expansive primary suite is a true sanctuary, complete with private office, custom walk-in dressing room, and a large balcony overlooking the grounds. Outside, the property is an entertainer's dream, featuring lush gardens, mature flowering trees, stunning 2019 Shoreline over-sized pool with an integrated spa and automatic cover, extensive landscape lighting and built-in grill. Further updates in 2024 include repaved driveway, new roof on main house, and a chip and putt area. A charming carriage house adds nearly 800 square feet of versatile space, offering four-car garaging and a private one-bedroom apartment--perfect for guests or staff.
