Beautiful custom home in the sought-after enclave of Thornwood Reserve offers a rare combination of custom-home living and the amenities of the Thornwood community and St Charles Schools. Set along a beautiful, tree-lined, gently curved street surrounded by upper-end custom homes, this exceptional property backs to mature trees and open land, creating a private and picturesque setting. Residents also enjoy access to Thornwood's clubhouse, pool, courts and more. This impressive brick and cedar home welcomes you with a two-story foyer flanked by elegant formal living and dining rooms. The dramatic two-story great room is the heart of the home, featuring a striking stone fireplace and an entire wall of windows overlooking the beautiful backyard setting. It flows seamlessly into the chef's kitchen and casual dining area, creating an inviting open-concept space designed for everyday living and effortless entertaining. The white kitchen features an oversized center island, pantry closet, upscale appliances and a convenient butler's pantry connecting to the formal dining room. The main level also includes a beautifully appointed wood-paneled den with custom built-ins, a stylish powder room and a spacious laundry/mudroom with abundant cabinetry and a back-hall closet. Upstairs, a custom iron-and-wood staircase leads to four bedrooms, including a sumptuous primary suite with a spa-inspired bath and dream walk-in closet. Bedroom two enjoys its own private bath, while bedrooms three and four share a thoughtfully designed Jack-and-Jill bath. The walk-out lower level takes entertaining to another level with a custom full bar, recreation room, second family room with stone fireplace, flex room that could serve as a fifth bedroom, full bath and abundant storage. With multiple gathering spaces, this level is perfectly suited for entertaining, guests, recreation or simply spreading out. The outdoor spaces are every bit as special. A huge upper deck feels like your own private treehouse, surrounded by trees and treetop views, while the walk-out level opens to a covered patio below. Brick and stone walkways, gorgeous mature landscaping, irrigation and established trees complete the exceptional setting. The side-load 3.5-car garage with tons of built-in storage adds both convenience and curb appeal. Home has a modern vibe and has designer touches throughout. All of this is ideally located within St. Charles schools and just minutes from grocery stores, Target, Starbucks, downtown St. Charles and the Randall Road shopping corridor. A truly special Thornwood Reserve property offering privacy, custom-home quality and the lifestyle amenities of one of St. Charles' most desirable communities.
