For decades, Castlewood Stables has been a familiar name in the area, offering a rare combination of location, land and remarkable infrastructure in the heart of St. Louis County. Established in 2006 and successfully operated as a boarding and training barn since its opening, the property is now ready for its next chapter. Set on 10.53 acres, Castlewood Stables offers exceptional versatility for an equestrian operation, equipment and vehicle storage, workshops, recreation, gatherings or other pursuits requiring substantial indoor and outdoor space. The equestrian facilities include a 32-stall barn with a tack room and two wash bays, along with a mirrored unfinished barn designed to accommodate up to 32 additional stalls, a tack room and wash bays. Currently used for equipment storage, the unfinished barn provides tremendous flexibility for future use. Additional improvements include a 40x60 hay and shavings barn, a lighted 100x140 indoor arena, a 100x200 outdoor arena and a 100x100 asphalt surface formerly used as a sport court and now providing substantial trailer parking. While its equestrian legacy is undeniable, the scale and flexibility of this property open the door to possibilities far beyond horses. Whether continuing its established use, exploring the potential for a new business venture, creating expansive recreational or training space, hosting gatherings or bringing an entirely different vision to life, the existing buildings and infrastructure provide an exceptional starting point. The 5,640-square-foot home offers 5 bedrooms, 4 full bathrooms and a flexible one-and-a-half-story layout. The main level features an open living area with high ceilings and a wood-burning fireplace, a spacious kitchen with custom cabinetry, granite countertops, a large island and walk-in pantry, a primary suite, two additional bedrooms and a dedicated office. The partially finished walkout lower level includes two bedrooms, two full bathrooms, a second kitchen, recreation space, laundry and abundant storage. The furnished walkout lower level, complete with two bedrooms, a full bathroom and a second kitchen, offers the potential for a separate apartment. Generous indoor and outdoor entertaining areas provide space for personal gatherings, barn events and larger celebrations. The property adjoins wooded government land, creating a private and scenic backdrop that feels removed from it all while remaining conveniently located. Continue the legacy of Castlewood Stables or reimagine this one-of-a-kind property for your own vision. An adjoining 20-acre parcel may also be purchased separately for additional privacy, recreation or expansion.
