1396 Niels Avenue is a fully rebuilt modern bungalow in Burlington's sought-after Mountainside neighbourhood - a rare find offering true quality beyond the typical cosmetic renovation. This 3+1 bedroom, 2-bath home was gutted to the cinder block walls and completely reconstructed with new framing, spray-foam insulation, upgraded sound-insulated interior walls, full wood baseboards and trim, and the 3/4" subfloor was reinforced with an additional 1/2" plywood for a solid feel and exceptional durability. The bright main level features a redesigned kitchen, modern bathrooms, new flooring, and thoughtfully planned living spaces. The fully finished basement adds a spacious family room, bar area, additional bedroom, and full bathroom - ideal for guests or entertaining. Outside, the home continues to impress with a double-wide driveway for up to six cars, fully redone landscaping, and a large insulated workshop with electrical - perfect for hobbies, storage, or future office use. The extra-deep backyard offers endless possibilities and includes a custom elevated treehouse, a standout feature that adds charm and character to the property. Located in a quiet, family-friendly area close to parks, schools, shopping, and major highways, this turnkey home delivers exceptional value. A must-see to truly appreciate the quality of the rebuilt and the uniqueness of the lot.
