Why Homeowners Trust Grandbuild Homes
Who We Are
At Grandbuild Homes, we’re more than builders — we’re problem solvers, planners, and craftsmen dedicated to building homes that last generations. With over 30 years of experience across the GTA, we’ve earned our reputation through transparency, precision, and a commitment to getting it right the first time.
Our design-build approach means we handle everything — from permits and architectural coordination to construction and finishes — under one trusted roof. Every decision, detail, and timeline is managed with care so you can enjoy a seamless experience from start to finish.
We believe a home should reflect the people who live in it. That’s why we take the time to understand your vision, your lifestyle, and the long-term goals behind your build. Whether it’s a new custom home, major addition, or complete rebuild, every project is approached with the same principle:
Built Once. Built Right.
From the foundation to the final fixture, each Grandbuild project combines craftsmanship, structural integrity, and timeless design — delivering homes that stand strong, perform beautifully, and hold their value for decades to come.

Custom Home Builds
We design and construct bespoke homes built on precision, premium materials, and enduring craftsmanship. From the first drawing to final handover, every detail reflects your vision — built once, built right.
Garden & Secondary Suites
Transform unused land into income-producing or multi-generation living space. We handle design, permits, and full construction — creating modern, self-contained suites that boost both property value and flexibility.
Home Additions & Expansion
Add new levels, extensions, or open-concept living spaces seamlessly integrated into your existing structure. We expand your home’s comfort, function, and value — with design continuity and expert project management.
Basement & Income Suites
Maximize your property’s potential with a fully legal, thoughtfully designed lower-level suite. From zoning and permits to design and construction, we deliver turn-key spaces that meet code, elevate comfort, and generate lasting value.
