Expand your living space and increase property value with East York's premier home addition specialists.
We handle all aspects of East York's specific zoning bylaws and Toronto building permits. This includes representing your project at the Committee of Adjustment for minor variances, ensuring your addition is fully compliant and legally protected.
Every addition undergoes a rigorous structural assessment by licensed engineers to ensure your existing foundation can support new loads. We use reinforced footings and high-grade framing materials to prevent shifting and ensure long-term durability in Ontario's freeze-thaw cycles.
Our additions incorporate spray-foam insulation, low-E argon windows, and integrated HVAC solutions specifically designed for the Toronto climate. This results in a new living space that is exceptionally comfortable and cost-effective to heat and cool throughout the year.
We begin with a site visit to assess your East York property's physical and regulatory constraints. Our designers create conceptual sketches that balance your space needs with structural requirements, providing a clear vision of what can be built within your budget.
Once the design is finalized, we engage structural engineers and submit comprehensive plans to the City of Toronto. In East York, this often involves navigating specific tree protection zones and site drainage plans, which we manage entirely on your behalf to ensure a smooth approval.
This is where your new space takes shape, starting with excavation or the removal of your existing roof. Our team works efficiently to 'dry-in' the new structure as quickly as possible to protect your home from the elements, ensuring all framing and roofing meet our high workmanship standards.
After the shell is complete, we install all electrical, plumbing, and HVAC systems, followed by insulation and drywall. Our finishing carpenters then take over to install custom cabinetry, flooring, and trim, culminating in a final cleanup and walkthrough to hand over your new living space.
Whether you need a minor variance depends on your specific lot coverage and the proposed height of the addition. Many East York lots are narrower than current bylaws allow, making the Committee of Adjustment a common step in the process. Our team handles the entire application and representation process to maximize your chance of approval.
A full second-story addition generally takes between 4 to 6 months from the start of demolition to final finishes. Factors such as weather, complexity of the architectural design, and material lead times can influence this schedule. We provide a detailed project timeline during the planning phase so you can make appropriate living arrangements during the construction.
Not all foundations are built to the same standards, especially in older East York neighborhoods. We perform a 'test pit' or structural assessment to determine the depth and thickness of your footings. If the foundation is insufficient, we can perform underpinning or utilize lightweight structural steel to ensure the addition is safe and stable.
Matching an addition requires a combination of architectural design expertise and skilled craftsmanship. We source matching bricks from local suppliers and use custom-milled trim to mirror your existing interior. Our design team focuses on rooflines and window proportions to ensure the new square footage looks like an original part of the house, not an afterthought.
Transform your property into a high-value asset by navigating Toronto's specific legal requirements for basement apartments and garden suites. This comprehensive guide from Built by Pros Inc. breaks down the zoning, permits, and construction standards needed to build a compliant and profitable secondary dwelling.

Learn MoreWe hired Built By Pros for a 600 sq ft rear addition to our bungalow in the Danforth area. Ricardo and his crew were amazing, finishing the structural work in just six weeks despite a very rainy spring. They matched the original 1940s brickwork so perfectly that you can't even tell where the addition starts. The new open-concept kitchen and family room have completely changed how our family uses the space.
Adding a second story to our East York semi-detached was a massive undertaking, but Suzanne made the design process seamless. She helped us navigate the tight space constraints and managed to fit three bedrooms upstairs where we thought we only had room for two. The project was completed on budget, and the glass railings on the new staircase are a stunning focal point.
I needed a professional office addition for my home-based business near Woodbine. Built By Pros delivered a beautifully insulated and soundproofed space that was ready for use in under three months. Their attention to detail with the electrical layout and networking ports was exactly what I needed for my tech setup. I highly recommend them for any custom space maximization projects.
