Welcome to 42 Lilac Ave! Tucked into the heart of Aileen-Willowbrook, this south-facing 4 bedroom, 3.5 bath semi-detached home brings Tudor-inspired character to one of Thornhill's most established family neighbourhoods. Freshly painted in soft neutrals, the main floor feels bright, calm and ready for your next chapter. Upstairs, four generous bedrooms give everyone room to spread out, while three and a half baths keep busy mornings moving. The real showstopper is out back: no rear neighbours, just open green space with a backyard backing directly onto Green Lane Park. Morning coffee with a view, room for the kids to roam, and a quiet, leafy outlook in every season. Families will love the location within the catchment of some of York Region's most sought-after schools, including St. Rene Goupil-St. Luke Catholic Elementary, Willowbrook Public School, Thornlea Secondary and St. Robert Catholic High School. Commuters are minutes to Highways 404 and 407, with easy access to Bayview, Yonge, transit and Finch Station, plus nearby shopping, dining, parks and the Thornhill Community Centre and Library. A rare blend of character, space and setting. Welcome home.
