On a very quiet Water Mill cul-de-sac, this gated 4,266+/- sq. ft. home has much to offer. Situated on 1.5+/- acres adjacent to Peconic Land Trust preserve, the home is set amid beautifully landscaped grounds with broad, open lawns and plenty of blue sky overhead. The spacious living room is essentially two rooms, with a fireplace; the entire south-facing wall is lined with large windows and glass doors flooding the space with light and opening to spacious wraparound decking overlooking the pool and grounds. The well-equipped kitchen also has plenty of windows, along with high end appliances, a large center island and wonderful built-in shelves, with plenty of room for a large dining table or seating area. Glass doors open to a covered part of the deck, ideal for al fresco dining. A junior master suite is also on the first floor. Upstairs are four additional bedroom suites, all with marble vanities and frameless glass-enclosed showers. The lovely master suite has French doors to a private terrace overlooking the pool and preserve, a large walk-in closet and bath with soaking tub, steam shower with bench, double marble vanity, bidet, marble walls and flooring and paneled wainscoting. Past the master is a huge bonus room with skylights and closet, which could become a media or recreational room, yoga studio, bedroom or office. From this room a rear staircase descends to a laundry, mudroom, garage and the kitchen/dining area. The lower level is partially finished, and an existing billiards and media area could easily be converted to a bedroom. There's plenty of additional space to customize to your needs. Outdoors enjoy the heated gunite pool with spa and waterfall as you relax in the sunshine, surrounded by beautiful plantings with the serene farm fields nearby and the ocean and bay within easy reach.
