Luxury custom homes built across Toronto’s finest neighbourhoods.
From Forest Hill and Lawrence Park to The Bridle Path, Rosedale, Lytton Park and Bedford Park, GrandBuild Homes designs and builds custom residences that suit Toronto’s most established streets. Whether you’re building new on an infill lot or replacing a tear-down, we manage every detail—design, permits, and construction—with the craftsmanship and care Toronto homeowners expect.

Custom Home Building in Toronto
GrandBuild Homes builds luxury custom homes throughout Toronto and the surrounding GTA. From sought-after central neighbourhoods like Forest Hill, Lawrence Park, Rosedale and The Bridle Path to family pockets such as Lytton Park, Bedford Park and Leaside, we create residences that fit the character of Toronto’s most established streets.
Building in the city brings its own challenges—tight infill lots, mature tree protection, Committee of Adjustment minor variances, and City of Toronto permit requirements. We handle all of it, guiding you from design through approvals to a finished, move-in-ready home.
Whether you’re tearing down and rebuilding, building on an infill lot, or undertaking a major whole-home renovation, our Tarion-licensed, family-run team delivers craftsmanship, transparency, and long-term value on every Toronto project.
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.

Working Process
How We Work
Building a custom home in Toronto should feel clear and controlled from day one. Our process starts with design and feasibility—assessing your lot, zoning, and goals—then moves through architectural drawings, City of Toronto permits, and any Committee of Adjustment approvals. From there we build with a fixed schedule, transparent budgeting, and a single point of contact, so you always know exactly where your project stands.
Solutions & Benefits
Every engagement starts with a clear scope and a realistic budget — then we protect both with disciplined planning, transparent reporting, and hands-on oversight from start to finish.
