Mid-Century Modern masterpiece designed by renowned architect, Edward Dart! Rarely does one find a gem such as this. A sprawling 17-acre estate was built in 1964, adjacent to 100+ acres of forest preserve. Dart's use of natural materials made him a unique mid-century modern architect. His use of local brick, gives the house a touch of humanity, as he would say. This pure mid-century modern home, with more than 7,000 square feet of living space includes a pool, pool house, studio (additional 325+ SF) 3-car garage, a 3-bedroom caretaker's cottage (additional 1,600+ SF) barn, outbuilding, paddocks, pond, and woods. This home transcends time with its innovative design and livable, warm spaces. It remains authentic and intact with its original plan - you will fall in love with the abundant natural light and mesmerizing views from the windows. Approaching the entrance, you will notice the barreled vault entry and custom-designed, two-inch-thick arched wooden door. Upon entering the home, you will be drawn to the eastern views of the grounds and atrium garden. Clerestory windows capture the light from the sky and the enormous brick hearth, the heart of the living room, enriches the lovely, grand space for entertaining. The large dining room, with a Dart-designed chandelier, overlooks the sparkling pool and pool house in the distance. The kitchen, with custom ebony wood cabinets, will delight with its original high-end stainless steel and black appliances. An additional butler's pantry, walk-in pantry, and breakfast room complete this extensive kitchen. The second-floor primary suite has sweeping views of the east and the adjacent 100+ acre forest preserve, with custom closets and original bathroom fixtures. The home boasts 3 additional second-floor bedrooms, one en-suite, and an additional pristine full bathroom. On the main level, there is a library/office with a full bathroom and guest suite with two bedrooms, one full bath, and a large sitting area. Additional features include a pool house with bathroom facilities and multiple areas for changing. There is also a separate studio with a full bath which can be utilized as a living space, an office, or art/yoga/exercise room. The home has been lovingly cared for and has one additional lot available for a separate building site on the grounds. This could be a very private family compound with multi-generational living possibilities. This truly spectacular Mid-Century modern home, grand and untouched, with strong lines yet graceful elegance, is a once-in-a-lifetime find. It blends beautifully with nature, and exudes warmth and comfort. Its rich history, its stunning design, and the privacy it offers, provides a truly amazing opportunity to live in such surroundings!
