Custom Homes & Additions

- Custom home builds
- Building additions & extensions
- Attic & third-floor conversions
Luxury homes, major renovations and additions across Toronto & the GTA — designed, engineered and built by one team, with the structural and steel-beam expertise other builders hire out.


Most builders design around the structure. We build through it.
For 14+ years, GTA Home Design Inc. has delivered 400+ projects across Toronto and the GTA — from full custom homes to open-concept transformations that start with removing the wall everyone else said couldn't move.
One team handles design, permits, engineering and construction. No hand-offs, no surprises — and structural work done by the people who actually specialize in it.
What We Build
Ground-up luxury homes and seamless additions that look like they were always part of the house.

Full-home transformations, kitchens, bathrooms and basements — designed and built by one team.

Steel beam supply, fabrication and installation by our family partner, GTA Beams.
A dark, unused attic became a full third storey — new bedroom, bathroom and living space — engineered, permitted and built by our own crew.
Free on-site visit. We look at the space, the structure, and what's actually possible.
Drawings, structural engineering and permits — stamped and submitted by our team.
Our own crews on site, one point of contact, and a schedule we actually keep.
Final walkthrough, clean site, warranty in writing. We don't disappear after the cheque.
"They removed a load-bearing wall and installed a steel beam to open up our main floor. Clean, on schedule, and the permit work was all handled for us."
