Home Additions & Extensions Toronto
Rear additions, second storeys, and structural extensions tied cleanly into your existing home.
Extensions & Additions done right.
An addition is the most cost-effective way to gain real square footage without leaving the neighbourhood you chose. The hard part is the connection: new foundation to old, new framing to existing structure, new roof lines that read as original.
We build additions from the footing up, with engineered structural details, integrated waterproofing, and finishes that match what is already there.
What you get
- Engineered footings and foundation tie-ins
- Waterproofing and drainage integrated from day one
- Structural work coordinated with permits and inspections
- Finishes matched to your existing home
