Rare find off Highway 79: three flat, buildable acres on a quiet cul-de-sac in St. Paul, addressed O'Fallon, in the Fort Zumwalt School District. The ground is wide open and level front to back - no grading headaches, no timber to clear, and an obvious build envelope the moment you walk it. Minimal restrictions mean no mandated builder, no architectural review board, and no clock forcing you to break ground. This future home offers the rare opportunity to create a completely personalized luxury retreat tailored to your vision, lifestyle, and needs. The proposed floor plan features 2,359 square feet with an open concept layout seamlessly connecting the kitchen and living room – perfect for entertaining; while the split bedroom floor plan is ideal for everyday living. Additional features include custom cabinetry, butler pantry, formal dining room, luxury primary bath and walk-in closets - every architectural and interior detail remains fully customizable to create a timeless, one of a kind residence. Three acres leaves room for an outbuilding, shop, garden, or a deep buffer from the neighbors, on an established street with substantial custom homes nearby. FEMA Zone X (unshaded), minimal flood risk. Enjoy the perfect blend of privacy and convenience, just minutes from Highway K, Bryan Road retail, I-70, and Hwy 40/61.
