Hiring a design-build firm means one team draws your renovation and builds it. That is a real advantage — when the firm is good. The way to find out is to ask better questions in the first meeting. Here are the ones we would ask before signing anything, and the answers worth listening for.
1. Who does the design work, and what are their credentials?
Ask who actually draws your project and what their training is. In Ontario, drawings submitted for a building permit need to come from someone qualified to produce them — a BCIN-registered designer, an architect, or an engineer, depending on the scope. If the firm outsources design, ask who to, and whether you will meet them. You want the person who plans your home in the room, not behind a subcontract.
2. Can I see the design before I commit to construction?
The honest structure is a design fee first: you pay for the drawings, you own the plan, and the construction price follows from it. Be careful with free design tied to a construction contract — a plan produced to win a signature serves the signature, not the home.
3. What exactly does the construction price include?
Ask for the line between included and excluded: finishes, fixtures, appliances, disposal, permits. A low number that excludes half the project is not a low number. The drawings should be detailed enough that the quote can be specific — that is the point of designing first.
4. How do you handle changes once the build starts?
Changes happen. The answer you want is boring: changes are priced in writing before the work is done, every time. The answer to walk away from is vague reassurance.
5. Who is on site, and how often will you be there?
Ask who runs the site day to day, and how often the designer — the person who drew the plan — walks the project. Design-build only delivers its promise when the design side stays involved through construction.
6. Who pulls the permit?
The firm should prepare the drawings and submit on your behalf. If a firm suggests skipping the permit on work that needs one, end the meeting. It is your name on the property.
7. Can I see a finished project — and talk to the client?
Photos show taste. A conversation with a past client shows how the firm behaves in month three, when the drywall dust is real. Any firm proud of its work will make the introduction.
8. What happens if we find something behind the wall?
Older homes hide surprises — wiring, plumbing, structure. Ask how unknowns are priced and communicated. A good firm tells you the risk honestly up front and prices the surprise when it appears, in writing, rather than burying contingency padding everywhere.
How we answer these at Studio Kimi
We are a design studio first, led by a BCIN-registered designer, with our own trades for the build. The design fee is agreed before any work starts, the drawings come before the construction price, we prepare and submit the permit set, and changes are priced in writing. If you are comparing firms for a renovation in Oakville, Mississauga or Burlington, bring this list to every meeting — including ours — and get in touch when you are ready to talk through a project.
Frequently asked questions
What should I ask a design-build firm before hiring them?
Ask who does the design work and their credentials, whether you can see the design before committing to construction, what the price includes and excludes, how changes are priced, who runs the site, who pulls the permit, and whether you can speak with a past client.
What is a red flag when hiring a design-build firm?
Free design tied to a construction contract, vague answers about how changes are priced, a quote that excludes major items, and any suggestion of skipping a required permit.
Do design-build firms handle the building permit?
A qualified firm prepares the permit drawings and submits on your behalf. In Ontario, permit drawings must come from someone qualified to produce them, such as a BCIN-registered designer, an architect, or an engineer, depending on the scope.
