This truly magnificent 10-acre waterfront compound on Long Island Sound has a remarkably private setting with 440' of direct water frontage. The panoramic vistas to the east and south across Cos Cob Harbor and out to the Long Island Sound provide an incredible array of breathtaking water views. The property is bordered to the south by the 50-acre Copper Beech Farm. The 5-bedroom shingle style residence was completely renovated in 2018 highlighted by an exquisite glistening kitchen and incredible bathrooms with extraordinary marble slab designs. In addition to the waterside pool and spa, the expansive compound includes a Vermont style barn serving as a guest house and party barn flanked by a lighted tennis court. This unique waterfront estate has a back country secluded ambiance, yet it is close to town. Truly a rare opportunity to acquire a world-class property and enjoy in the current state or build an incredible great estate.
