Tucked at the end of a quiet cul-de-sac on a wooded .61-acre lot in established Fairwood East Subdivision, this custom ONE OF A KIND tri-level offers something genuinely rare in O'Fallon — true privacy, architectural character and a spacious lot in the heart of District 90. The dramatic foyer opens to a vaulted great room with exposed wood beams, skylights, a floor-to-ceiling stone fireplace, and a wall of built-in cabinetry and bookcases. The eat-in kitchen blends everyday function with entertaining-ready style: solid surface counters, wood cabinetry, double pantry, coffee bar, built-in double oven, stainless refrigerator and a cooktop surrounded with a granite countertop & backsplash. A pass-through opens to the great room, and a three-panel sliding glass door floods the breakfast nook with natural light while opening to the rear brick patio. Steps from the kitchen, an oversized formal dining area connects to a separate formal living space — perfect for holiday gatherings and entertaining. Upstairs, four bedrooms include three secondary bedrooms with newer wood flooring and a full hall bath, plus a generous primary suite featuring a sitting area, walk-in closet with built-in laundry chute, and ensuite bath with dual vanity, jetted tub-shower with body sprays, and tile flooring. The partial basement has a walk-out with a large office/bonus room/bedroom boasting direct exterior access — ideal for remote work or guests — along with a half bath and laundry room with utility sink. Step outside to a multi-level paver and exposed-aggregate patio completely surrounded by mature woods, creating a private park-like retreat. Recent updates include a new roof, gutters, and vinyl siding. Additional features: zoned HVAC, 200-amp service, oversized side-entry 2-car garage, hard-surface flooring throughout. Quick I-64 access puts Scott AFB and downtown St. Louis within an easy commute, while historic O'Fallon shopping and dining are minutes away. Schedule your private tour today.
