Permits, zoning guidance, and turnkey construction for compliant backyard homes across Ontario.

Affordable housing has become an essential part of Ontario’s evolving housing landscape, and well-designed ADUs, garden suites, and laneway homes are helping homeowners create attainable living options without the cost, disruption, or long timelines of traditional construction.

At FlexoBuild, we design and build high-quality, Canadian-made affordable homes that deliver modern comfort, long-term durability, and energy efficiency in compact, well-planned backyard footprints.

Whether you’re helping elderly parents downsize into a safe, independent space, creating a private and dignified home for adult children, or adding an attainable housing option to your property, our ADU and prefab home solutions are designed for fast installation and lasting value.

How Modular Homes Fit on Existing Residential Properties

Accessory dwelling units (ADUs) allow homeowners, municipalities, and communities to add much-needed housing without changing neighbourhood character. Modular ADUs can be installed quickly on existing lots, offering a practical solution for multigenerational living, affordable housing, or transitional housing needs.
