16420 S River Road A truly one-in-a-lifetime opportunity to own a remarkable 26-acre private estate, split almost evenly between lots 16410 and 16420 and zoned for horses or agriculture, with the HOA permitting up to four horses on site - all with the rare convenience of city water and sewer service to the main property. Pass through your private gated driveway to discover over 6, 300 square feet of livable space thoughtfully designed for entertaining and quiet retreat alike, featuring an incredible library complete with a hidden door bathroom, a serene sunroom showcasing the abundant natural wildlife, a gorgeous wine cellar, and heated floors warming the basement, family room, and sunroom. The grounds are nothing short of extraordinary: a private pond gently fed by an elegant fountain and stocked with crappie, bass, bluegill, channel cat, bullhead cat, and sterilized grass carp; a wood-burning fire pit for evenings under the stars; a relaxing hot tub; a private driving range; greenhouses; a garden shed; and even active bee colonies and chickens that supply fresh honey and farm-fresh eggs. Approximately eight acres of farmland and tranquil river frontage backing directly to the DuPage River complete the unmatched outdoor experience, all enhanced by sophisticated low-voltage landscape lighting that brings the property to life after sundown. A heated garage and a secondary garage - perfect as a workshop with convenient attic space ready to build out - provide ample room for vehicles, hobbies, and projects. Despite the country-like seclusion, you are less than a 15-minute bike ride to Downtown Plainfield, close to top schools, shopping, dining, and everything the area has to offer. Experience the privacy and serenity of country living paired with every nearby suburban amenity - a truly rare and unrepeatable opportunity.
