Professional design build solutions to expand your home or office footprint with ease.
We specialize in rear and side-yard extensions that blend perfectly with the existing architecture of your East York home. Our team matches brickwork, rooflines, and trim to ensure the new addition looks original to the structure while providing modern internal amenities. This approach increases your property value by maintaining a cohesive aesthetic across the entire building.
For professionals needing a dedicated headquarters at home, we build customized office additions with separate HVAC zones and soundproof exterior walls. These spaces are designed to meet commercial-grade standards for electrical and data cabling, allowing you to run a full-scale operation from your property. This saves on external lease costs while providing a private, professional environment for clients and focused work.
Our deep knowledge of East York's specific zoning bylaws allows us to maximize your allowable lot coverage without triggering unnecessary legal hurdles. We handle all Committee of Adjustment applications and represent your interests to the city, ensuring your addition to maximize space is legally compliant. This expertise prevents project shutdowns and ensures your investment is fully protected by the appropriate permits.
We begin by reviewing your East York property survey to determine building envelopes and lot coverage limits. This step prevents the common pitfall of designing a space that the city will not permit, saving you thousands in wasted architectural fees. We clearly explain what is possible on your specific lot before any contracts are signed.
Our designers create detailed floor plans that focus on maximizing every square inch of your new living or working area. We involve structural engineers early in the process to ensure the transition between the old foundation and the new one is perfectly stable. This phase includes choosing finishes like windows and roofing that match the local East York aesthetic.
We handle the entire submission process with the Toronto Building Department, including responding to any notices or requests for additional information. In East York, this often involves navigating Committee of Adjustment hearings if the addition requires minor variances. We take the stress out of the bureaucracy by acting as your authorized agent.
Our crews execute the construction with a focus on weatherproofing and structural integrity, especially during the critical phase where the existing roof is tied into the new addition. We maintain strict schedules to ensure your home is open to the elements for the shortest time possible. Finally, we perform a deep clean and final walkthrough to ensure every detail meets our 'Built By Pros' standard.
Lot coverage limits in East York typically vary between 30% and 40% depending on your specific zoning sub-designation. We perform a detailed property survey to determine your exact limit and can often apply for minor variances if your addition to maximize space requires a slightly larger footprint. Our goal is to balance your need for space with the city's requirements for soft landscaping and drainage.
An addition will likely lead to a reassessment of your property value by MPAC, which can result in a tax increase. However, the added market value of having an extra bedroom or a professional workspace usually far outweighs the incremental tax cost. We can provide estimates on how the increased square footage might impact your valuation based on recent sales in the East York area.
Yes, under the city's new garden suite bylaws, many East York properties are eligible for a detached secondary dwelling in the backyard. We handle the specialized utilities, such as separate water and electrical lines, and ensure the structure meets all fire and safety codes. This is an excellent way to create a separate working space or a rental unit without altering your main house.
We source matching or complementary materials, such as specific brick blends or vintage-style trim, to ensure a seamless visual transition. Our design team often uses architectural features like shared rooflines or matching window proportions to tie the old and new sections together. In many East York additions, we recommend a 'transitional' style that respects the home's history while offering a modern, open-concept interior.

Learn MoreWe needed to add a second story to our cramped bungalow to accommodate a new home office and a master suite. Ricardo and the team at Built By Pros were incredible, finishing the 800 sq ft addition in just four months despite a very rainy spring. They managed the tight setbacks on our East York street perfectly, and the transition from the old brick to the new siding is gorgeous. Suzanne's advice on the staircase placement saved us so much space in the original living area!
Built By Pros helped us design and build a rear extension that served as a studio for my graphic design business. The project involved digging a new foundation and integrating a modern glass-walled room into our traditional 1940s home. They were extremely respectful of our neighbors, keeping the site clean and within noise bylaws, which I really appreciated in this quiet neighborhood. The energy efficiency of the new space is top-notch; it stayed warm all through the last Toronto winter with minimal heating.
After looking at moving, we decided to invest in an addition to maximize our living space in East York instead. The team added a beautiful sunroom and expanded our kitchen using high-quality cedar and custom glasswork. We were worried about the permits because our lot is oddly shaped, but Built By Pros handled the city paperwork without us having to lift a finger. The final result exceeded our expectations, and our home feels twice as big as it did before.
