Stunning Sheridan Model offering nearly 3,000 square feet of exceptional living space with extensive upgrades throughout, including a desirable breakfast room addition and a matching expanded basement addition that provides even more versatile living space. This thoughtfully designed floor plan welcomes you with a grand foyer, beautiful open staircase, powder room, mudroom, and an impressive chef's kitchen featuring an expansive center island, stainless steel appliances, stone countertops, and abundant cabinetry-all opening seamlessly to the spacious great room. A private first-floor study with double doors offers the perfect work-from-home space, while the sun-filled breakfast room addition showcases vaulted ceilings and overlooks the backyard. Upstairs, you'll find four generously sized bedrooms, a convenient second-floor laundry room, and a luxurious primary suite with an upgraded tray ceiling and spa-inspired bath featuring a soaking tub, separate shower, and dual vanity. Meticulously maintained by its original owner, this 10-year-young home has been freshly painted throughout and offers an impressive list of upgrades, including hardwood flooring throughout, recessed lighting, Ethernet wiring, a finished attached two-car garage with additional outlets and an electric vehicle charging station, rough-in plumbing for a future fourth bathroom in the expanded basement, and a security system. The solar panel system is discreetly located out of view from the front of the home and offers tremendous savings with a transferable contract, resulting in a $0 electric bill while powering the home and EV charging station. Outdoor living is just as impressive with a beautifully landscaped, fully fenced backyard featuring a new 25' x 15' patio with a sitting wall and mature arborvitae providing exceptional privacy-perfect for entertaining or relaxing. Ideally located near I-90, Algonquin Commons Shopping Center, dining, and parks, and served by the highly sought-after Huntley School District, this exceptional home truly offers luxury, efficiency, and convenience in one remarkable package.
