Legal basement suites
A second dwelling unit adds monthly income and appraised value, but only if it is legal. GWC designs the suite to code, files the permit, builds it with licensed trades and closes it out with the city so it is registered and insurable.

How we work
Hands-on leadership on every site. You get one point of contact, daily progress updates and quick answers when something comes up.
We walk the property, confirm what is possible under code, and write a clear scope with fixed pricing.
Our BCIN designer prepares drawings and files the permit application with your municipality.
Licensed trades, a dedicated site lead, clean work sites and daily updates.
We schedule every inspection, close the permit and hand over a finished, registered space.
For investors & realtors
GWC works with investors on flips, income suites and multi-unit conversions, and structures the build so it qualifies for CMHC MLI Select financing where it applies: up to 95% loan to value and 50-year amortization on eligible multiplex, rental and conversion projects.
