Hälsa 230 Royal York is the first in a series of mid-rise infill developments in Toronto, ON, by Windmill Developments and Leader Lane Developments. This project utilizes Intelligent City’s prefabricated mass timber building system, including columns, floor cassettes, and envelope panels, marking the first full-system project produced with their prefab technology.
The Hälsa brand embodies healthy urban living. The developers chose a prefab mass timber system to achieve multiple objectives: offering a market-differentiated product in Toronto’s transit-served neighborhoods, meeting sustainability requirements tied to One Planet Living Fund financing, and creating a repeatable, adaptable solution that maintains a strong brand identity without starting from scratch for each site.
Delivered through a design/build approach, the project brings together LWPAC (a sister company) as the architectural firm and Intelligent City as the superstructure and envelope provider. Designed with Passive House standards, the building will achieve LEED Platinum certification while also meeting Toronto’s stringent Green Standard requirements.
By maximizing space on a tight urban site and leveraging mass timber at a scale where concrete construction is often cost-prohibitive, Hälsa 230 Royal York was able to proceed as a market-rate rental despite economic fluctuations throughout the design and construction phases.
