Property Description
Welcome to this fully renovated and stylish 4-bedroom, 1.1-bathroom brick ranch, ideally located in one of Mount Prospect's most desirable neighborhoods. Situated within the top-rated District 57 school system and just steps from the soon-to-be revitalized Lions Park (2025-2027), this home offers both modern elegance and unbeatable convenience. Step inside to discover a bright and spacious open-concept living and dining area-perfect for entertaining. Rich walnut-stained hardwood floors span the main level and stairway to the lower level, complemented by fresh custom paint by Benjamin Moore throughout. The stunning kitchen features 42" shaker-style cabinets with abundant storage, a pantry, honed soapstone countertops, and premium KitchenAid Professional Series stainless steel appliances. A 3-person counter sits beside expansive west-facing windows that flood the space with natural light and overlook the new concrete patio and large, landscaped backyard. A versatile family room or home office, located on the main floor, adjacent to the kitchen, opens directly to the patio through sliding glass doors-ideal for indoor/outdoor living. Three generous main-floor bedrooms offer ample closet space. The beautifully remodeled full bathroom showcases oversized green ceramic tiled shower walls, marble hexagon flooring, a stylish walnut double vanity with quartz countertops, and matte black lighting/mirror and plumbing fixtures. The powder room, adjacent to the kitchen, is equally refined with black marble hexagon tile flooring, a chic vanity with honed soapstone countertop, and bold, color-saturated walls, ceiling, and trim. A newly added mudroom includes a built-in bench with cubbies above and below, a large coat closet, and direct access to the attached one-car garage with excellent storage options. Downstairs, you'll find an expansive finished basement that includes oversized marble-look tiled laundry room with high-efficiency side-by-side washer/dryer, quartz folding counter, stainless steel utility sink, and ample cabinetry; a massive recreation room, ideal for media, games, or a home gym; a spacious fourth bedroom; a large storage area and separate utility/HVAC room with potential to add a second full bathroom (then would be two full bath, one 1/2 bath). Step outside through the rear sliding doors to enjoy the newly poured concrete patio, mature trees, and perennial plantings that enhance the private backyard retreat. Gorgeous matte black lighting fixtures throughout. Additional updates include: all-new electrical wiring, new water supply and drain lines, new PVC sewer line from the house to the city main, newer roof, newer windows, and gutter guards, new furnace, new a/c and new water heater. Newly Landscaped front beds with boxwoods and black mulch. Located in a quiet neighborhood close to schools, parks, public pools, shopping centers, and dining options, this home combines modern upgrades with timeless comfort.
