A Once-in-a-Lifetime Estate on Over 9 Private Acres. Welcome to one of the most extraordinary luxury estates in St. Charles, where timeless architecture, exceptional craftsmanship, and unmatched versatility come together on more than 9 beautifully landscaped private acres. Offering over 12,000 square feet in the main residence, an incredible multi-purpose clubhouse, and 10+ garage spaces, this is more than a home-it's a private compound designed for the way you live, work, entertain, and relax. Designed by renowned Scholz Design and masterfully built in 2003, this architectural masterpiece is tucked away at the end of a private lane, accessed by a charming bridge over Ferson Creek and secured behind elegant wrought-iron gates. Every detail reflects luxury, from the soaring 22-foot great room with Palladian windows and crystal chandeliers to the gourmet chef's kitchen, executive library, rotunda turret, and spectacular first-floor primary suite with its own private gym access. The walkout lower level is an entertainer's dream featuring an authentic Irish-imported oak bar, climate-controlled wine cellar, recreation areas, fireplaces, fitness room, vault room, and more. Outside, resort-style living awaits with a sparkling pool and spa, expansive stone terraces, outdoor fireplace, and resurfaced tennis, basketball, and pickleball courts-all surrounded by mature trees and breathtaking grounds. One of the estate's most remarkable features is the 3,618-square-foot detached Clubhouse, formerly a residence with its own address. This incredibly flexible space offers five bedrooms, three bathrooms, two kitchens, soaring vaulted ceilings, a walkout lower level, and its own three-car garage. Whether you envision an in-law residence, guest house, private executive office, golf simulator, bourbon lounge, cigar room, fitness studio, creative workspace, home business, entertainment venue, or the ultimate kids' retreat, the possibilities are virtually endless. Car enthusiasts will appreciate more than 10 garage spaces, providing abundant room for collector vehicles, recreational toys, and hobbies. Located just 35 miles west of Chicago and minutes from premier golf clubs, equestrian facilities, shopping, dining, and highly acclaimed St. Charles School District 303, this is a legacy estate that offers an unmatched combination of privacy, luxury, functionality, and prestige. Rarely does a property of this caliber become available. This is your opportunity to own one of the most iconic private estates in all of St. Charles.
