Structural Renovations
Your home's potential starts with its structure. Greyfield removes load-bearing walls, installs engineered beams, and reconfigures floor plans — all engineered and permitted to Ontario Building Code. Before any finishes are chosen, we assess what your home can do and build from there.
Learn MoreLoad-Bearing Wall Removal
Removing a wall is a structural decision, not just a demolition job. Greyfield assesses load paths, coordinates with engineers, sizes and installs the beam, pulls the permits, and finishes the ceiling — one team managing the full process from assessment to completed room.
Learn MoreBasement Underpinning
Your basement ceiling doesn't have to stay where it is. Greyfield lowers basement floors by up to 36 inches — engineer-coordinated, fully permitted, and sequenced to keep your foundation intact throughout. The right first step toward a legal suite or livable lower level.
Learn MoreBasement Renovations
A basement that actually works starts with what's behind the walls. Greyfield handles everything from structural assessment and underpinning through to legal secondary suite construction, full finishing, and permit sign-off — built to the same standard as the rest of your home.
Learn MoreHome Additions & Extensions
More space without the move. Greyfield builds rear extensions, second storey additions, and in-law suites that are structurally integrated with your existing home — not just attached to it. Permit-managed from zoning review through to final occupancy.
Learn MoreDesign-Build Renovations
One team from first sketch to final inspection. Greyfield's design-build process brings structural knowledge into the design stage — so the plan that gets drawn is the plan that gets built, on budget and without surprises.
