Assembly Corp. Midrise

1598-1600 Queen Street East uses a panelized modular wood construction system, enabling off-site prefabrication and faster on-site assembly for a mid-rise, infill context. The approach standardizes the structural and unit “kit,” while allowing some flexibility in layouts and façades.

This is a mass timber building that is designed to minimize the embodied carbon emissions. It is also designed to be very energy efficient, and to minimize carbon emissions during operation.

Replicability

A panelized modular system is readily transferable to other urban sites. The walls, floors and core panels are prefabricated and trucked to the site, where they are assembled. This approach shortens construction schedules and reduces neighbourhood disruption, while cutting costs. Standardized, repeatable mid-rise homes (with flexible plans and street-level retail options) simplify approvals and procurement. This Canadian example on Queen Street East in Toronto shows how panelized mass-timber or wood systems can be erected in weeks on a downtown building site, demonstrating a clear path for cities to scale “missing-middle” housing with predictable costs and timelines.
