State of Housing: Prefab, Mass Timber, and 3D Printed Housing Making Inroads in the GTA
AI Article Summary

The article discusses how the Greater Toronto Area (GTA) is increasingly adopting innovative construction methods like prefabrication, modular housing, and mass timber to address housing shortages and sustainability goals. These methods, including early ventures into 3D printing, offer faster, more sustainable home-building alternatives. Notable developments include modular housing projects at 1120 Ossington Avenue and 185 Cummer Avenue, and a mass timber facility by Mattamy Homes' founder. The push towards prefabrication aligns with net-zero standards and seeks to reduce construction timelines and carbon footprints.

What This Means for Canadian Contractors

This project shows how prefab and modular housing can significantly reduce construction times and costs, offering potential solutions for urban housing crises. For Canadian builders, this means incorporating advanced manufacturing techniques could lead to quicker project completions and lower carbon emissions. Embracing these technologies may require changes in workforce training and supply chain adjustments to support scalable production.
