Custom Home Builds: Your home should be built once, and built right — without shortcuts, and without compromise.

Home Additions & Expansions: The best additions don’t look like additions — they look like the home was always meant to be this way.

Basement & Income Suites: A legal, well-built suite pays you back twice — in monthly income and in long-term property value.

Garden & Secondary Suites: A standalone suite adds living space, flexibility, and value — without touching the home you already love.

Insurance & Fire Restoration: In a difficult moment, you need one team that handles everything — and answers for everything.

Real Estate Investment Projects: Every dollar of scope is weighed against return — that’s how disciplined builds become profitable assets.

Process in Action

Frequently Asked Questions

We’ve become the best at what we do by being transparent, available, and accountable. Here are the questions our clients ask most.

How much does it cost to build a custom home in the GTA?

Cost depends on size, design, materials, and complexity. Our custom homes typically start at $300 per square foot. After an initial consultation, we provide a detailed, transparent estimate for your specific project.

How long does it take to complete a custom home?

Most custom homes take 12–18 months from design to move-in, depending on the size of the home, municipal permit timelines, and design complexity. We build a realistic schedule with you up front — and manage it with discipline.

Do you handle permits, architecture, and engineering?

Yes. We are a full-service design-build firm. Architectural design, structural engineering, permits, inspections, and construction are all managed by one accountable team — you never have to chase multiple trades.

Are you licensed and insured?

Yes. GrandBuild Homes is Tarion-licensed, HCRA-regulated, and fully insured. Every new home we build is covered by Tarion warranty protection.

What areas do you serve?

We’re based in Mississauga and build across the Greater Toronto Area — including Toronto, Oakville, Brampton, Vaughan, Caledon, Richmond Hill, and surrounding communities.
