Expand your footprint with seamless residential and commercial additions built for GTA life.
We handle the entire application process with the City of Toronto, including Committee of Adjustment hearings for minor variances. This prevents months of delays and ensures your addition is 100% legal and compliant with the latest zoning bylaws.
For our commercial clients, we integrate accessibility features from the ground up to meet Ontario standards. This includes barrier-free entrances and specialized washroom designs that ensure your business is welcoming and legally protected from compliance issues.
Our designers specialize in matching the unique brickwork and trim common in Toronto's diverse neighborhoods. We ensure the transition between the original structure and the new addition is invisible, preserving your home's historic charm while adding modern utility.
Before drawing a single line, we audit your property against Toronto's zoning bylaws to see what is possible. We identify potential hurdles like tree protection zones or heritage designations that could impact your footprint. This prevents costly redesigns and ensures your vision is grounded in local reality.
Our designers create detailed CAD drawings that go beyond aesthetics to include full engineering specs for HVAC and structural loads. We submit these to the Toronto Building Department and handle all follow-up queries. This stage is critical for ensuring your addition is safe, energy-efficient, and fully legal.
This phase involves the heavy lifting: excavation, foundation pouring, framing, and roofing to make the addition watertight. In Toronto's tight neighborhoods, we use specialized equipment to protect adjacent properties. We focus on getting the 'shell' finished quickly to minimize your home's exposure to the elements.
Once the structure is secure, we integrate electrical, plumbing, and high-efficiency HVAC specifically calculated for the new volume. Our craftsmen then handle the fine details, from trim matching to luxury flooring and paint. This is where your new space truly becomes a seamless part of your Toronto home or office.
In the current Toronto market, home additions generally range from $300 to $500 per square foot, depending on the complexity of the build and the quality of finishes. Factors like second-story vs. ground-level extensions, the need for structural reinforcement in older homes, and the current cost of raw materials in Ontario will influence the final quote. We provide a detailed breakdown during our consultation to ensure there are no surprises.
Many home additions in Toronto require a minor variance if the project exceeds the permitted lot coverage or infringes on required setbacks from property lines. This process involves the Committee of Adjustment and can add 3-6 months to your timeline. Our team manages this entire process, preparing the necessary documentation and representing your project to city officials to maximize your chances of approval.
Yes, we can perform construction through a Toronto winter by using specialized techniques such as heated enclosures for concrete pouring and prioritizing the 'weathering-in' of the structure during milder windows. While some external finishes like parging or landscaping may need to wait for spring, the interior framing, insulation, and finishing can proceed without issue. This often allows homeowners to have their new space ready for the busy summer season.
A standard rear addition in Toronto usually takes between 4 to 8 months from the start of construction, following a 3-month design and permitting phase. Timelines vary based on the scale of the plumbing and electrical work required and the speed of city inspections. We provide a projected schedule before the project kicks off and provide weekly updates so you are never left guessing about the progress of your home expansion.

Learn MoreWe hired Built By Pros for a 600 sq ft rear addition to our bungalow in North York to create a new master suite. Ricardo and his team managed the tricky foundation work near our old oak tree, which required special city permits I didn't even know existed. The project was completed in 5 months, and the match on our 1950s red brick is absolutely perfect. It looks like it has always been there, and the spray foam insulation they recommended keeps the room perfectly warm even in January.
Our family was outgrowing our small semi-detached home, so we opted for a full second-story addition. Suzanne walked us through every design choice, helping us maximize the narrow footprint with clever built-in storage and a vaulted ceiling. The crew was extremely respectful of our neighbors—a huge deal in East York where houses are so close together. Despite a two-week delay on our custom windows, they made up time elsewhere and stayed within our $250k budget.
We needed to expand our medical office in Toronto to include three new consulting rooms and a broader reception area. Built By Pros handled the commercial construction with zero interruptions to our patient schedule by working weekends for the heavy structural phases. Their knowledge of AODA requirements was clear, as we passed our city inspections on the first go. The custom reception desk they built is the first thing patients see and it looks incredible.
