Welcome to 284 Union Boulevard, a stunning home on a 100' x 160' lot-just over one-third of an acre-nestled on one of Old Westmount's most picturesque tree-lined streets. Offering over 3,000 square feet of beautifully updated living space, this residence blends mid-century architecture with elegant, modern finishes. Old Westmount is among Kitchener-Waterloo's most coveted neighbourhoods - defined by mature trees, character homes, and walkable access to Westmount Golf & Country Club, Belmont Village, the LRT, and Uptown Waterloo. Inside, expansive corner windows fill every room with natural light and serene views of the landscaped, completely fenced-in yard. The living room overlooks lush gardens, while the family room opens to a spacious patio-perfect for entertaining or quiet evenings outdoors. In 2020, the primary suite and ensuite were fully renovated with custom cabinetry, Kohler fixtures, and in-floor heating. The lower level was redesigned with a wet bar, walk-in shower, and in-floor heat. The home features beautiful engineered hardwood floors (throughout most of the main floor) and modern vinyl plank on the upper level & lower level, complemented by custom built-ins in the office, dining room, and front hall. Outdoor living shines with a 2023 patio expansion and inground trampoline, ideal for family enjoyment. The boiler and hot-water tank were replaced in 2025, and the former cold room was transformed into a walk-in cooler - a unique touch for entertainers. With parking for six and surrounded by mature greenery, 284 Union Boulevard captures the essence of Old Westmount living-refined, private, and effortlessly sophisticated.
