A once in a generation opportunity to own one of Barrington Hills most significant private lakefront estates. Set along 450 feet of pristine shoreline on exclusive Hawley Lake, this remarkable 12,000 square foot residence offers an irreplaceable combination of privacy, architectural scale, and breathtaking waterfront views. Custom built for its original owner and offered for the first time; the estate presents an exceptional opportunity to enjoy today while creating a personalized legacy for generations to come. This architecturally distinctive, private waterfront retreat is defined by dramatic rooflines, rhythmic dormers, expansive horizontal scale, and a refined palette of natural stone and wood detailing, creating a timeless resort-inspired aesthetic. 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.
