Discover a truly extraordinary residence where luxury meets distinction in this magnificent three-story, 6-bedroom, 8.2-bath royal retreat, set on nearly two acres in prestigious Lake Forest, known as The Hidden Museum. Home to a museum-quality art collection, this architectural masterpiece has never been used as a full-time residence and remains in mint condition. Enter through a gated circular driveway and be greeted by timeless elegance, exceptional millwork, and a combination of gleaming marble and hardwood flooring throughout. Designed for both entertaining and refined living, the home features a breathtaking great room with soaring 40-foot ceilings, a grand fireplace, walls of windows that fill the space with natural light, and access to the expansive grounds. A 4-person elevator provides seamless access to all floors. The main level boasts two kitchens-one currently in use and another potential main kitchen intended for the green room adjacent to the great room. The first-floor primary suite is a true retreat, complete with a spacious walk-in closet, a serene sitting room, and a luxurious bathroom with dual vanities, a walk-in shower, and space for a central soaking tub. Upstairs, you'll find three generously sized en-suite bedrooms, a loft, and a versatile bonus room. The third level adds even more flexibility with an additional en-suite bedroom and bonus space, ideal for guests or creative uses. The fully finished basement is a showstopper, featuring a full kitchen, a spa-style bathroom, and an unused indoor pool with room to create a full wellness retreat or entertainment zone. Beyond the main residence, a coach house offers a 4-car garage and private living quarters with a bedroom suite above, ideal for guests, extended family, or staff. An additional wing, connected by a breezeway, offers two more rooms and a full bath, while a separate pool house further enhances this estate's rare offering. Situated on a massive corner lot, the flat, leveled backyard is a blank canvas ready to become your dream outdoor oasis. Ideally located near the Metra station, shopping, dining, and scenic lakeside attractions, this home offers unparalleled space, privacy, and potential. A rare opportunity to own one of Lake Forest's most unique and prestigious estates.
