Why Homeowners Choose ScaleBig
There are a lot of contractors in the GTA. Here is what makes us different.
Family-Owned & Operated
ScaleBig Construction is a family business. Ahmad manages every build personally — you always know who's responsible for your project.
In-House Interior Designer
Dina, our professionally trained in-house designer, handles colour consultations, space planning, 3D renderings, and finish selections — all under one roof.
Held to One Standard
If a trade's work doesn't meet our standard, they redo it before we move on. You inherit the result, not the rework.
Trusted Trades Network
We've built lasting relationships with skilled, reliable trades who deliver consistently. Every person on your job site is vetted, trusted, and accountable.
About ScaleBig Construction
A family business, built around standards.
ScaleBig Construction was built on a simple belief — that homeowners deserve a contractor who genuinely cares. Not just about the finished product, but about every decision, every detail, and every trade that touches your home.
Ahmad, our founder and project manager, brings over 7 years of hands-on construction experience — including 4 years working directly under a custom home builder where he developed deep expertise in structural framing, project management, and high-end residential construction. He knows what good work looks like because he's built it himself. He's not afraid to ask a trade to redo something if it doesn't meet the standard. That standard never moves.
Dina, our in-house interior designer, is professionally trained with deep experience in colour, space planning, finish selection, and photorealistic 3D renderings. With design and construction under one roof, decisions move faster, details are caught earlier, and what's shown in the rendering is what's delivered in the finished space.
When you hire ScaleBig Construction, you're not hiring a faceless company. You're hiring people who care.

Dina
In-House Interior Designer
10+ years in colour, space planning, 3D renderings, and finish selection. Design and build under one roof.

"The design process was seamless — Dina had a vision for our space that we never would have thought of ourselves. The 3D rendering matched the final result perfectly."
Sarah K.
Google Review
"They were honest, on time, and didn't cut a single corner. When one trade's work wasn't up to standard, Ahmad had it redone without us even asking."
