mcCallumSather has announced the completion of 1620 Main St. E., a six-storey, 42-unit affordable housing project delivered in partnership with CityHousing Hamilton. The building, which officially opened on July 14, 2025, is the first of its kind in North America to combine Canadian-sourced mass timber construction with Passive House certification in an affordable housing context.

The project was designed and constructed through an integrated design-build model, and aims to offer a replicable approach to delivering high-performance housing with long-term value for residents and municipalities. Located in the heart of Hamilton’s east end, the building aims to be an example of sustainable and rapid housing delivery which offers affordable units as well as a blueprint for municipalities facing urgent housing pressures.
