Welcome to 21 Alder Crescent, a spacious 4-bedroom detached home tucked onto a quiet, mature street in the heart of Blackburn Hamlet. With a generous floor plan, multiple living spaces and a beautifully private yard, this is a home with room to settle in and make your own. The main level offers a bright living and dining area, along with a separate family room just off the kitchen featuring a cozy gas fireplace and direct access to the backyard - a great layout for both everyday family life and entertaining. Hardwood and tile flooring add warmth and character throughout the principal spaces. Upstairs, you'll find four impressively sized bedrooms, including a spacious primary bedroom, giving everyone room to spread out. The finished lower level adds even more flexible living space and is ideal for a rec room, home office, gym, playroom or hobby area. Outside is one of the home's standout features: a private, hedge-lined backyard surrounded by mature greenery. The deck provides a peaceful spot for outdoor dining, morning coffee or evenings gathered with friends around the fire. An attached garage and ample driveway parking complete the package. Set in established Blackburn Hamlet, 21 Alder offers the space and privacy of a mature neighbourhood while remaining close to parks, schools, transit and everyday amenities. A spacious family home in a setting that's increasingly hard to find.
