Home Additions in Toronto
More space, built to match your existing home.
A second-storey or rear addition in Toronto has to respect the existing structure, the setbacks, and the streetscape it sits on. Nexon Build delivers home additions across Toronto — from The Annex, Riverdale, Leslieville to the streets in between, with three experienced partners on site and every project tracked in Buildertrend.
Toronto is known for century semis, Victorian row houses, and sharp modern infills on tight downtown lots. Adding space to a Toronto home — a second storey, a rear addition, or a garden suite — has to respect the existing structure, the lot's angular planes, and the City's permit process. Nexon Build designs and builds additions across the GTA that integrate seamlessly with your home, inside and out.

Home Additions in Toronto: what to know
We coordinate the structural engineering, confirm the existing foundation can carry the new load, and manage the variance and permit process with City of Toronto (Toronto Building & Committee of Adjustment). Because we work across the old City of Toronto constantly, we know how this jurisdiction reviews home additions — which keeps your Toronto project compliant and on schedule from day one.
