Home Additions in Toronto & the GTA
You love your home and your neighbourhood; you just need more room. A RezTorIt home addition gives you all the space you’ve been dreaming of without the cost and upheaval of moving.
Designed and built by one integrated team, your addition will look and feel like it was always part of the house: bigger, better, more beautiful, and unmistakably yours.
Types of Additions We Build
Every home and family is different, so we build additions in every shape and size:
- Second-story additions in the GTA that double your living space without expanding your footprint.
- Rear and side extensions for bigger kitchens, family rooms, and primary suites.
- Sunrooms and four-season rooms that bring the outdoors in, year-round.
- Above-garage suites for in-laws, guests, or rental income.
- Bump-outs and enclosed porches that reclaim underused space.
Whatever the type, your design-build home addition is designed to match your home’s architecture, rooflines, and finishes so it blends seamlessly, inside and out.

Vision,
Built to Code, Built to Blend
An addition is only as good as what’s behind the walls. We engineer every project for lasting structural integrity:
Foundations and structural tie-ins designed by licensed engineers.
Full Ontario Building Code compliance on every detail.
Toronto zoning and by-law reviews, including Committee of Adjustment support when needed.
Exterior materials carefully matched to your existing brick, siding, and stonework.
Heating, cooling, and electrical systems integrated with your current home.
The result: an addition that’s safe, efficient, and indistinguishable from the original.
