Exceptional Thornwood home situated on one of the neighborhood's premier lots, tucked away on a quiet cul-de-sac and backing to expansive open green space and mature trees for beautiful views and added privacy. Served by highly desirable St. Charles Community Unit School District 303, this impressive brick-front home offers extensive upgrades, generous living spaces, and exceptional indoor and outdoor entertaining areas throughout. The welcoming foyer with hardwood floors and a Juliet balcony opens to a dramatic two-story family room with a fireplace and expansive windows that fill the space with natural light, creating an impressive centerpiece for the home. The spacious family room flows seamlessly into the well-appointed kitchen featuring stainless steel appliances, granite countertops, abundant cabinetry, a center island with seating, and a walk-in pantry. The bright eat-in area features a butler's pantry and sliding glass doors that open to the outdoor living space. Formal living and dining rooms offer additional space for gatherings, while the first-floor office with built-in cabinetry and backyard access provides a convenient work-from-home setting. A powder room and laundry room with access to the attached three-car garage complete the main level. Upstairs, the oversized primary suite offers a private retreat with a tray ceiling, morning bar, separate sitting area, and custom-organized walk-in closets. The luxurious ensuite bath features granite-topped vanities, a two-person shower, jetted tub, and heated stone flooring. Three additional generously sized bedrooms provide comfortable accommodations for family and guests, including one with a private ensuite bath, while the remaining two share a Jack-and-Jill bathroom with dual granite-topped vanities. The fully finished basement delivers an impressive extension of the home's living and entertaining space, featuring two large recreation areas, a dry bar, decorative stone fireplace, billiards area, dedicated exercise room, temperature-controlled wine cellar, and a half bath. The outdoor setting is a true standout. The fully fenced backyard backs to open green space rather than another home, creating a rare sense of privacy and openness seldom found in the subdivision. The sprawling brick paver patio, deck, and fire pit create an inviting setting for gatherings, while a separate covered patio and screened gazebo with a brick fireplace provide additional spaces to dine, relax, and enjoy the outdoors across multiple seasons. Professional landscaping and mature trees enhance the beautiful setting, creating an exceptional backdrop for outdoor living. Beyond the home, Thornwood offers an exceptional community lifestyle with access to the Thornwood Sports Core, featuring a clubhouse, pool, water slide, playground, tennis courts, and sand volleyball court. Nearby parks, walking trails, and bike paths provide even more opportunities for outdoor recreation. The location also offers convenient access to Randall Road shopping and dining, as well as the vibrant downtown areas of St. Charles and Geneva. A rare opportunity to own one of Thornwood's standout lots, combining a premier cul-de-sac setting, added privacy, beautiful open views, and outstanding living spaces.
