This serene property, high on a bluff with dramatic, sweeping views across Napeague Bay, consists of four separate lots totaling 4.35+/- acres. The main house, a prairie contemporary designed by Bill Chaleff of Chaleff & Rogers Architects, shows influences of Frank Lloyd Wright. The home faces north, with panoramic bay views from huge windows and glass doors, and each room also has high, south facing windows insuring the interior is always awash in natural light. Exquisite craftsmanship is evident throughout this distinctive home. All windows, doors and shades are handmade; all woodwork, built-in shelving and cabinetry is custom. First floor living areas are open concept, with the living room, dining area, kitchen and breakfast area all flowing together. Special features include a three-sided fireplace in the living room, granite countertops and Viking and Miele appliances in the kitchen, and adjacent butler's pantry with additional dishwasher and refrigeration. A powder room, office with sliding glass doors to the lawn, TV room with window wall, sliding glass door and south window, and a gallery-like hall lined with south-facing windows complete the first floor. Upstairs is the master suite, with large water-view windows, high south window, custom walk-in closet and cabinetry, dressing/makeup area with window, bath with tumbled marble walls and floor, marble sink, and whirlpool tub. There are two en-suite bedrooms, another bedroom with adjacent bath, and an office with a terrace and powder room. Above the garage is a gym and second laundry room which could become another large bedroom suite. There is an oversized heated gunite pool with automatic cover, an outdoor living room on a covered patio, with hot tub, an outdoor shower and a stairway to a sandy beach. Across the street on a separate property on Accabonac Harbor is a private floating dock. The grounds are beautifully landscaped, with mature trees, flowering shrubs, a vegetable garden and bocce court with seating. There is a service entrance, and parking for staff and guests. The two-story three bedroom, two bath guest house has a two-car garage and separate driveway.
