From the Government of Canada:
Introducing a Standardized Housing Design Catalogue
Standardized housing design catalogues were originally a tool used by the federal government between the late 1940s and 1970s. Budget 2024 will propose $11.6 million to reinvent this 1940s catalogue for 2024.
The catalogue will reduce costs and timelines for home building by providing a standard set of designs that will provide economies of scale and reduce barriers to entry in the homebuilding sector.
In Fall 2024, we will publish the first phase of the catalogue which will include up to 50 low-rise housing designs—including accessory dwelling units, modular homes, and multiplexes—for use across Canada. The next phase of the catalogue will include mid-rise and single-family home designs.
