Big Kuntry Farms is a versatile 45+ acre property for sale in Washington County, Missouri, located just southwest of Old Mines along Highway 21. Combining a newly constructed barndominium with wooded acreage, hunting land, recreational property, and an extensive trail system, this property offers an exceptional opportunity for a permanent country home, weekend getaway, hunting retreat, homestead, or private ATV property. A deeded gravel driveway leads to the centerpiece of the property: a 100-by-42-foot barndominium constructed in 2025. Built on a 6-inch concrete slab, the fully finished structure features 16-foot walls, full spray-foam insulation, and complete utilities. The versatile floor plan combines comfortable living space with substantial garage, equipment storage, workshop, and entertainment areas. A pitched front porch with custom barnwood trim opens into the expansive garage and entertaining area. Two oversized garage doors provide convenient access, including one tall enough to accommodate a high-end RV. The garage features custom-finished floors with French drains, along with a dedicated bunk room with a kitchen sink and full bathroom, providing additional space for a guest. The main residence features custom hardwood finishes, hardwood flooring, carpeting, and an open, lofted living area and kitchen. The home includes two spacious bedrooms, two full bathrooms, a laundry room, and ample storage. Above the garage, a large lofted bonus room is already plumbed for an additional bathroom. This unfinished space offers flexibility for additional bedrooms, a game room, home office, bunk room, or private recreational area. Along the north side of the building, a 100-foot covered overhang provides substantial equipment storage and could also be converted into an outdoor living, entertaining, or gathering area. The surrounding Washington County hunting and recreational acreage includes mixed hardwood timber, a creek bottom, previously-established food plots, and an extensive trail system. UTV-accessible trails extend around the property’s perimeter, providing convenient access for hunting, ATV / UTV recreation, wildlife management, and property maintenance.  With a combination of barndominium living, hunting acreage, hardwood timber, trails, and quiet setting, Big Kuntry Farms offers a rare opportunity to own a private rural escape in Washington County, MO. The property is conveniently located within approximately an hour of St. Louis County and the Highway 44 corridor while providing the privacy and space of a country setting.
