Home Additions & Extensions in Toronto

Home additions and extensions offer homeowners the perfect solution to expand their living space without the expense, disruption, or uncertainty associated with moving. At MR Homes Construction, we specialize in builder-led home addition services throughout Toronto and the Greater Toronto Area, emphasizing proper planning, structural integration, and code-compliant execution for every custom home project.  


Whether you’re considering a second storey addition, extending the rear of your home, building above a garage, or reconfiguring layouts to create additional bedrooms, bathrooms, or living areas, we handle the project from feasibility through construction. Each addition is meticulously planned to integrate both structurally and visually with the existing home while adhering to Toronto zoning by-laws and Ontario Building Code requirements.  


From rear and side extensions to comprehensive second-storey additions, our team of general contractors coordinates engineering, permits, and construction to ensure that the new space is functional, durable, and built correctly from the ground up, including expert framing techniques to enhance the overall quality.

Why a Home Addition Is a Smart Choice in Toronto

In Toronto’s high-cost and competitive real estate market, moving is not always the most practical solution. A well-planned home addition allows you to increase square footage, improve functionality, and enhance long-term property value while staying in the neighborhood you already know.


Home additions can address changing needs such as growing families, work-from-home requirements, or multi-generational living. When designed and built properly, an addition can modernize layouts, improve flow, and significantly strengthen resale value without taking on the risks of purchasing a new property.
