Build X Design helps Toronto homeowners and small investors turn underused lots into multi-unit housing. Feasibility, zoning, design, permits, and construction guidance, handled by people who do this every day. The result is a multiplex that actually gets built, and holds up under Toronto’s changing rules.
Multiplex conversions, top-up additions, and missing middle infill across Toronto neighbourhoods. Every project starts from what the site allows and what the city requires, and aims to pull the most livable units out of the lot.
We take homeowners and first-time developers from idea to approvals with a clear plan for multiplex design in Toronto. Feasibility, zoning review, architectural design, and construction guidance, in one process.
Before you design anything, we check whether your Toronto lot can carry a fourplex, sixplex, or other multi-unit build. What the zoning allows, where the site fights you, and how many units realistically fit, so you’re not guessing on the deal.
We turn existing houses and buildings into working multi-unit homes, reconfiguring the interior and planning the retrofit around how people will actually live in each unit. Most of this is Toronto multiplex conversion work.
Third-storey additions, rear additions, or a full new multi-unit build. We design to get more out of the lot while staying inside Toronto’s zoning and approvals rules.
Beyond housing, we design branded and experiential spaces: pop-ups, temporary exhibits, retail environments, and product installations. Same process, different canvas.
Victoria Suen leads Build X Design. She trained in architecture, design, and branding at firms in Toronto, Vancouver, and New York, and now walks Toronto clients through the design, approvals, and build of their multiplex, with a clear eye on what it takes to pencil out as a real development.
Our work goes beyond multi-unit housing. We’ve drawn and permitted a wide range of architectural projects, and that range sharpens how we approach every multiplex.
