Situated on a coastal waterway on Contentment Island in Darien, CT, this beautiful stone-and-shingle three-bedroom house is a dream. The house sits on almost an acre of land, with a backyard that leads to a 12x20-foot dock. Its many indoor and outdoor amenities include a movie theater, wine room, basketball court, swimming pool, hot tub and several patios. It’s eco-friendly to boot: The house is geothermal, and has solar panels and a rainwater collection system.
