We’re excited to share that 1620 Main St. E. has received the Third Award for Sustainable Project of the Year (Built) in the Rethinking The Future Awards!

More than an award, this marks another milestone in mcCallumSather’s commitment to high-performance, prefabricated, modular housing—a vital approach as we address the growing need for sustainable, affordable urban homes.

As one of the first multi-residential, mass timber, Passive House projects in Hamilton, 1620 Main St. E. integrated modular construction strategies to improve energy performance, reduce construction timelines, and minimize disruption to the surrounding community.

This isn’t a prototype stage or pilot stage. This is a complete proof of concept. These elements—mass timber, Passive House, rapid housing— work extremely well together. Replicable buildings that affordable housing communities could deliver starting tomorrow.”
