Home Additions in Markham
More space, built to match your existing home.
A second-storey or rear addition in Markham has to respect the existing structure, the setbacks, and the streetscape it sits on. Nexon Build delivers home additions across Markham — from Unionville, Cathedraltown, Markham Village to the streets in between, with three experienced partners on site and every project tracked in Buildertrend.
Markham is known for heritage Main Street homes and large modern subdivisions. 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.
