Make memories with this exceptional private backyard living space featuring beautifully-curved stone retaining walls, a fire pit cove, a high-end spa on the lower level beneath the covered deck, and a TV with ample outlets. When you are ready to come inside, relax in front of the fireplace and then retire to a spacious master bedroom with a recessed ceiling and oversized walk-in closet. The walk-out basement contains surround sound, a full bath, and a recreation room (easily converted to fifth bedroom). The spa and upstairs HVAC are less than two years old. There is plenty of storage space and also a separate 18'x9' work area in the garage (in addition to three car bays). A central vacuum system covers all three floors. Keep things green with the irrigation system which includes a drip line for the flower beds. Your future home is located in a very family-friendly neighborhood within a short walk to the O'Fallon Family Sports Park.
