Located down a winding, two-lane private road on a glacial ridge and nestled among mature trees, this one-of-a-kind property is surrounded by the beauty of Franklin Creek State Natural Area, offering the ultimate private retreat. The home is perched above the creek, giving a treehouse-like feel from every level. As you enter, you're welcomed by a spacious foyer and an open-concept layout. The eat-in kitchen and dining area are designed for entertaining, with abundant cabinet storage, prep space, a large island with seating, and room for a full-sized dining table. The main floor features a spacious master suite with a fireplace, walk-in closet, and en-suite bath, plus an additional full bath with a walk-in shower. Upstairs, you’ll find two generously sized bedrooms, a full bathroom, two cozy activity nooks, and a private deck overlooking the creek—perfect for morning coffee in the treetops. The lower level expands the living space even further with a library area and fireplace, a massive family room with a second fireplace, and walk-out access to another deck with stunning views. Additional flex spaces include a potential fourth bedroom, rec room, and bonus room with its own full bath. A two-car attached garage is complemented by a 2-story, 36x70 outbuilding—ideal for equipment, vehicles, or hobbies. Surrounded by the Franklin Creek State Natural Area’s 882 acres of hardwoods, springs, and wildlife, this property is also close to Nachusa Grasslands, Gremel Nature Preserve, Lowden Miller Forest, and other natural areas that provide exceptional opportunities to hike, fish, observe Bison, birdwatch, and explore. Located a few minutes outside of the historic town of Franklin Grove. Nearby are the quaint and historic towns of Dixon and Oregon, situated along the Rock River. Excellent golf courses, such as Lost Nation Golf Course just a short drive away. This spacious home in the woods feels far away from city life but still features easy access to I-88 to Chicagoland and I-39 to Rockford. 3 miles to Franklin Grove, 12 miles to Dixon, Rochelle, I-88. The home has a brand new roof and is waiting for its new owner to put their own touches on this one-of-a-kind property.
