A truly one-of-a-kind 15-acre estate in the heart of O’Fallon, offering a rare combination of luxury, privacy and versatility. The property consists of an impressive main residence, two outbuildings, a separate guest house, inground pool and pond, creating a setting unlike anything else in the area. Whether envisioned as a private family compound, multi-generational estate, or a space to operate a small business, the possibilities are endless. The all brick and stone executive atrium ranch offers nearly 8,000 sq ft of beautifully appointed living space with 5 bedrooms, 6 bathrooms and timeless architectural detail throughout. Multiple gathering spaces, custom finishes and an expansive finished lower level provide an exceptional setting for everyday living and entertaining. The first outbuilding offers ~7,000sqft of space, currently configured to include an event space with a full kitchen, office spaces with a full bathroom and an expansive garage/workshop with garage door access. A second ~3,500 sq ft building offers unfinished space with bath rough-ins, loft, laundry connections and running water, ready to be customized to suit your vision. A private guest house further enhances the property, complete with a full kitchen, bathroom, living room and sleeping area. Beyond these structures, an inground pool and pond surrounded by sprawling acreage complete this private property. With approximately ~3 acres zoned residential and the remaining ~12 acres zoned commercial, opportunities of this caliber are exceptionally rare.
