Welcome to Castle Rock--where quality craftsmanship, thoughtful design, and larger lot sizes create a refined yet approachable custom-home experience. This beautifully built two-story home offers elevated finishes and everyday livability in a desirable St. John location. Inside, you'll find hardwood floors, a gas fireplace with brick surround and wood mantel, and a home office just off the foyer. The open great room flows into the breakfast area with sliding doors to a covered patio and spacious backyard--an uncommon feature in today's market. The kitchen blends style and function with quartz countertops, a large island, tile backsplash, stainless steel appliances, and a large walk-in pantry. Upstairs, the primary suite features a soaking tub, custom-tiled walk-in shower with glass enclosure, and generous his-and-hers walk-in closet spaces. Three additional bedrooms, a full bath, and a second-floor laundry with washer, dryer, and sink complete the level. Additional highlights include a mudroom with built-in bench and storage, oak staircase with custom railing, and a full unfinished basement plumbed for a future bath. This unique home includes a fully brick and stone exterior, covered front porch, professional landscaping, concrete driveway, and dual garages (2.5-car plus 1-car) with epoxy floors, gas heater, and extra storage. No HOA, close to parks, shopping, dining, and just minutes from the Illinois border.
