Set along an extraordinary 450 feet of private shoreline on the exclusive Hawley Lake, this 12,000-square-foot estate represents one of the most significant lakefront offerings in Barrington Hills. Offered for the first time, the custom-built residence showcases exceptional scale, craftsmanship, and a setting rarely found in today's market. Privately tucked down a long, tree-lined drive, the property offers a remarkable sense of seclusion just minutes from the Village of Barrington, Metra access, and major roadways. The home is defined by grand, light-filled interiors, where beamed ceilings, expansive windows, and thoughtfully designed living spaces create a seamless connection to the surrounding landscape. Nearly every principal room captures unobstructed water views, creating a constant and calming connection to the lake. Designed for both comfortable everyday living and effortless entertaining, the residence offers 5 bedrooms and 6.1 baths, including a spacious kitchen with adjoining breakfast room, a grand family room with wet bar, formal living and dining rooms, sunroom and a richly appointed wood-paneled library. Recreational amenities further elevate the home, highlighted by an indoor pool and hot tub with dedicated lounge areas, along with a walk-out lower level featuring a recreation and game room, dual dressing rooms, and direct access to the grounds and lakefront. The main-level primary suite is privately positioned and serves as a peaceful retreat, complete with vaulted ceilings, sweeping water views, a spa-like bath with steam shower and whirlpool, and generous dual dressing areas. All secondary bedrooms are en-suite, offering comfort and privacy for family and guests on the 2nd level with a private loft/lounge area overlooking the family room. The expansive grounds are beautifully maintained and thoughtfully arranged, with an expansive deck leading to the sweeping lawn areas, mature landscaping, and a commanding lakefront presence. The 450 feet of shoreline provides panoramic views and endless opportunities for lakeside living-boating, swimming, fishing, and paddleboarding. A rare offering that combines scale, privacy, and premier waterfront, this is a home that can be enjoyed immediately while offering enduring value in one of Barrington Hills' most sought-after locations.
