Welcome to your own private resort-set on over 25 lush, rolling acres in prestigious Barrington Hills. This extraordinary estate, 17 years in the making, blends timeless elegance with resort-style living and endless potential to create an equestrian estate or simply a private sanctuary. From the moment you arrive, you're greeted by a sense of serenity and grandeur. Thoughtful architectural details define the home, including rich walnut trim, custom plaster crown moldings, herringbone hardwood floors, and multiple fireplaces that add warmth and charm throughout. The outdoor spaces are truly a showpiece-lushly landscaped and designed for relaxation and recreation. A sparkling in-ground pool, expansive stone patio, built-in firepit, and elegant gazebo offer a luxurious setting for entertaining or unwinding in nature. The grounds also include a built-in grill in the sunroom for year-round al fresco dining. Whether you're hosting summer soirees or enjoying a quiet evening under the stars, this property lives like a five-star retreat. And for those with equestrian dreams, the acreage offers the perfect canvas to create a world-class horse property. There's ample space for barns, paddocks, and riding trails-all surrounded by the natural beauty and privacy Barrington Hills is known for. Inside, the home offers equally impressive living and entertaining spaces: a dramatic two-story entry with dual bridal staircases, soaring ceilings in the living room, a formal dining room with butler's pantry, and a richly appointed study. The chef's kitchen and breakfast room are a daily delight, with panoramic views of the grounds. The first-floor primary wing is a private sanctuary with dual spa-like baths, oversized walk-in closets, and a dedicated office. Upstairs, two spacious bedroom suites each feature ensuite baths and double walk-ins. The lower level is packed with amenities including an oversized rec room, a fitness studio, wine cellar, sauna, and even a hidden passageway for a touch of whimsy. A separate heated four-car garage includes a charming one-bedroom, 1.1-bath guest house-perfect for extended family, guests, or a live-in caretaker. This is more than just a home-it's a lifestyle. Secluded yet just minutes from downtown Barrington, Metra, shopping, dining, and award-winning District 220 schools. A rare opportunity to own a true retreat, with all the makings of a luxury equestrian estate.
