Residential ◆ Design + build
The feeling of the space comes first.
We work with you to design-build what you want the right way. We ask the critical questions to make sure we tailor the design of your space, then we build it with expert craftsmanship.

Who This Is For
For Homeowners Who Want It Done Properly.
We work with homeowners across Montréal, and the surrounding North and South shore who are renovating the home they plan to stay in. Kitchens, bathrooms, extensions, basements, full renovations: we handle the design and the build, so you have one point of contact from start to finish.
Before we draw a line
What We Do
01
Kitchens & Bathrooms
The two rooms that change a house the most. Plumbing, electrical, cabinetry, finishing, all by the same team.
02
Extensions & Additions
Adding space seamlessly. Foundation, framing, envelope, and clean tie-ins to what's already there.
03
Basements & Income Units
Finishing a basement or adding a rental unit, with permits and code handled from the start.
04
Full Home Renovations
The whole house, room by room, on a clear schedule and a single contract.
How It Works
Five steps, from the first conversation to the final walkthrough. You always know where the project stands.
01
Discovery Call
We listen, and we ask the critical questions. Why are you making these changes? Who is going to live here? What is your budget? We want the real need before we talk materials.
02
Design & Selections
We draw the project and make the choices together: plans, materials, finishes. You see what it will look like before we start.
03
Estimate & Contract
A detailed price, line by line, with the schedule. No surprises mid-project: what is written is what gets built.
04
Build
Our team takes over the site. One project manager, regular updates, and a site kept clean.
05
Walkthrough & Follow-Up
We walk it together, clear the punch list, and stay in tough after the keys are handed over.

Frequently Asked Questions
Do I need to hire my own architect?
Not necessarily. We do design and build under one roof. If your project needs plans stamped by an architect or engineer, we coordinate that with our partners and it stays inside the same contract.
Which areas do you serve?
Montréal, Laval, the North Shore and surrounding areas. We're based in Mascouche. If you're not sure whether we cover your area, just ask.
How long does a project take?
It depends on scope and permits. A bathroom is a few weeks; an extension is several months. We give you a realistic schedule with the estimate, not an optimistic date we are going to miss.
Do you handle the permits?
Yes. Municipal permit applications are part of the mandate. That is exactly the kind of headache we take on.
Are you licensed and insured?
Yes. Quatria Construction inc. holds RBQ licence 5864-3800-01 and is in good standing with CNESST and CCQ.
