We are happy to work with Irvi Design for our legal unit in Oakville. Bao and team are extremely helpful in getting the building permit. They spend lot of time listening our requirements and did an excellent job on design. They have good understanding on building code and city specific requirements. When I need some clarifications, Bao has reached city of Oakville and Halton region and got required information. Quick response and very professional team.

It was a pleasure working with Bao. She was very informative and knowledgeable. We had to get a permit to legalize our basement and it was one of the smoothest experiences I have ever had. Bao handled all inquiries with the municipality until the permit was obtained. I highly recommend Irvi Design.
