Nestled on over 12 acres in the Grace Estates and bordered by a 500+ acre nature preserve ensuring privacy in perpetuity, The Bar House is a testament to modern elegance and exquisite design. Featured in numerous publications, this architectural masterpiece designed by Audrey Matlock and built by Lettieri Construction boasts an L-shaped modernist structure, with one story gracefully engaging the landscape at ground level and the other elevated to offer access to a lush green roof and breathtaking views of the entire property and its surrounding landscape. The home is strategically positioned at the highest point of the property to maximize sunlight and views. The exterior facade exudes a precise and striking quality that contrasts with the natural surroundings. As you step inside you'll find interior spaces thoughtfully designed to reflect an appreciation for nature and modern living, with sightlines throughout that allow one to engage with the landscape. Featuring 9000+/- sq ft of living space, the home offers five bedrooms, five full and two half bathrooms, and open living spaces with floor to ceiling glass doors that seamlessly flow from the house to the outside spaces, creating an effortless connection between indoor and outdoor living. The main floor encompasses a breathtaking great room with 12-foot ceilings, a double-sided black basalt fireplace, and dark bluestone radiant flooring. The chef's kitchen is outfitted with marble countertops and appliances by Blue Star which include a double oven with french doors and 8-burner stove top. Completing this level are two ensuite guest bedrooms, powder room, laundry room, and a mud room with abundant storage. The second story wing offers discrete rooms along a windowed corridor with sweeping views of the pool and courtyard, and includes a gym, a spacious office that could be converted to a 6th bedroom, laundry room, and sun-filled den that connects to the roof deck. Also along this level are two ensuite bedrooms, as well as the exquisite primary suite with a sleek fireplace, walk-in closet and private patio. The opulent primary bathroom is outfitted with Boffi and Grohe fixtures, and boasts a stunning White Thassos marble double vanity, Turkish marble walls and floor with radiant heat, soaking tub, and double open rain showers. Built into the gentle slope of the property is an attached fully finished multi-use studio with a floor to ceiling glass wall, as well as the oversized 2 car garage and extensive storage space. The striking relationship between the home and its surroundings is enhanced by the treatment of the exterior space as an extension of the architecture. The heated 60' gunite pool and spa are nestled into a courtyard within the linear volumes of the home, while the adjacent covered terrace includes the open air kitchen equipped with Viking grill, stovetop, refrigerator, and a Kalamazoo gas pizza oven. The al fresco living/dining areas are anchored by a massive outdoor fireplace. Carefully curated landscape designs throughout the property draw striking parallels between manmade beauty and the natural surroundings, creating an ambiance of serene elegance. A grove of pear trees extends towards the hidden sunken DecoTurf tennis court, while to the north, native vegetation seamlessly blends into the forest landscape. The environmentally responsible design seamlessly incorporates both passive and active sustainable strategies - building orientation, south overhangs, east/west sunshades, green roofs, and geothermal heating/cooling all ensure a harmonious balance between luxury and sustainability. Situated nearly equidistant from Sag Harbor and East Hampton villages, less than a mile to Alewive Brook Landing Beach with stunning sunset views over Sag Harbor Bay, and just a short distance to Cedar Point County Park, The Bar House is truly one of a kind property that not only presents an awe-inspiring, tranquil setting but also stands out for its exceptional design and style.
