Commercial & Retail Interior and Exterior Design in Greater Montréal

Fees depend on square footage, complexity and finishes. Commercial designers commonly bill hourly, as a flat project fee, or as a percentage of construction cost (roughly 8–15% for full design services on retail fit-outs). Custom millwork, storefront work and procurement add cost. As a design-build firm we give one combined design-plus-construction estimate up front, so you see the total number before committing.

Yes. A renovation permit and an updated occupancy permit (certificat d'occupation) are typically required, and each borough sets its own rules. In Quebec, plans for many commercial alterations must be sealed by an OAQ architect or an engineer depending on the building's size and use. We handle drawings, sealed plans where required, and the borough permit process as part of the project.

Both. We design interior layouts, finishes, lighting and fixtures alongside exterior elements such as façades, signage, entrances and storefronts. Coordinating them keeps the brand consistent and avoids conflicts between trades. In Montréal, exterior and signage changes often need separate borough approval and must meet façade standards, which we factor into the design and permit work from the start.
