A design-build custom home builder manages the entire project from start to finish, including architectural design, structural engineering, building permits, and construction. Working with a design-build company means you work with one team for the entire project, which improves communication, reduces delays, and helps keep the project on budget and on schedule.

The cost to build a custom home in Toronto, Mississauga, Oakville, Burlington, and North York typically ranges from $350 to $600+ per square foot, depending on the size of the home, structural complexity, and level of finishes. Custom homes with luxury finishes, basements, and high-end features may cost more.

The timeline for a home addition typically looks like this: Architectural drawings and engineering: 2–3 weeks City permits and approvals: 4–12 weeks Construction: 7–12 months Timelines can vary depending on the size of the addition, complexity of the project, and city permit approval timelines in Toronto, Mississauga, Oakville, and surrounding areas.

You need architectural drawings, structural engineering, energy efficiency compliance documents, and building permits before you start construction. Depending on your project, you may also need a property survey, grading and drainage plans, HVAC design, heat loss calculations, plumbing drawings, electrical layouts, and other supporting reports. We can manage this process for you from design through permit submission.
