About this home
Set on a picturesque 1-acre walkout lot in Steeplechase—one of O'Fallon's most coveted neighborhoods - this home delivers the rare combination of timeless architecture, thoughtful renovations, and exceptional versatility. This predominantly brick ranch offers over-the-top livability with an open, split-bedroom design featuring 4 bedrooms, 3 baths, and effortless main-level living. Vaulted ceilings, walls of windows, and rich engineered hardwood flooring create an open and light-filled interior that feels both sophisticated and inviting. The primary suite has been reimagined as a private sanctuary, complete with a spa-caliber bath showcasing a custom walk-in tiled shower, oversized jetted soaking tub, and refined designer finishes. Both secondary baths have also been beautifully updated, creating a home where every space reflects the same level of care and quality. At the heart of the home, the chef's kitchen {w/ access to covered deck} is designed for gathering, offering granite countertops, an oversized center island, new stainless steel appliances, and seamless flow into the hearth room anchored by a gas fireplace. A spacious main-floor laundry room is conveniently located just off the oversized three-car garage.
The finished walkout lower level extends the home's entertaining and living space with large secondary living areas, 5th bedroom, 3rd full bath and opens to a resort-inspired backyard highlighted by a stunning saltwater gunite pool in the fenced backyard. An additional detached guest house creates endless possibilities for extended family, long-term guests, a private office, fitness studio, or creative retreat, while the lower level provides abundant additional storage.
Beyond the aesthetics, the investment has already been made. Significant capital improvements—including the architectural shingle roof, HVAC system, water heater, siding, windows, and more—provide peace of mind for years to come.
Properties offering this level of privacy, flexibility, and thoughtful updating in Steeplechase rarely become available, and is positioned to evolve with you at every stage of life....
