Case Study: Scaling a Montreal Interior Design Firm

A Montreal interior design firm can scale most reliably by standardizing delivery, delegating production work, and matching service scope to project type. The strongest pattern in the sources is a shift toward documented, full-service workflows for large, long-duration projects, combined with systems that let the firm serve clients remotely without losing quality.

For a case study framing, the scaling strategy would look like this:

• Define a clear service model
  West of Main positions itself as a full-service firm for medium-to-large projects, managing procurement, contractor coordination, and quality control from start to finish. That kind of end-to-end scope is easier to scale when the firm has a repeatable delivery model rather than custom one-off service for every client.

• Document the project process
  Andrew Mitchell’s discussion on scaling an interior design business emphasizes that firms need a “really solid process” for delivery before building fees or trying to grow further. He also stresses a staged approach where each step follows the last, covering plans, specifications, documentation, and quoting.

• Build systems around communication and presentation
  Rebecca Hay’s interview with Sascha Lafleur says virtual or remote service can still support full-service design if communication is strong and presentation packages are exceptionally detailed. This suggests that scaling does not require sacrificing service quality, but it does require more structure in client communication.

• Invest in people, not only the founder
  Lafleur describes business growth as “a leap of faith in people” and says the firm expanded by investing in its team rather than trying to do everything personally. For a scaling case study, this supports a staffing model where the founder shifts from producer to leader, with team members handling defined parts of the workflow.

• Use firm size and project duration as operational constraints
  West of Main notes that full-service projects typically last at least one year, and new builds can take up to three years. Longer timelines make it even more important to have standardized milestones, role clarity, and quality checks so the business can manage multiple active projects at once.

• Position the firm for larger, more complex work
  ACT Architecture Design presents itself as a firm handling both large- and small-scale projects, including high-end residential and commercial work. That kind of breadth suggests scaling can also come from expanding the mix of project types, not just increasing volume within one niche.
