Expand your footprint with premium custom home additions designed for modern Markham lifestyles.
Proud to serve communities throughout Markham, ON
We specialize in matching existing exterior finishes, from specific brick hues in older Markham Village homes to modern siding in Cornell. Our goal is to ensure the addition looks like it was part of the original blueprint, preserving curb appeal and property value. This includes meticulous detail work on rooflines, window casements, and masonry.
With the rise of remote work, we design sound-proofed, professionally lit office additions that provide the separation required for productivity. These spaces features high-speed data cabling, custom cabinetry for organization, and independent climate control to ensure a comfortable environment throughout the work day. Transform a backyard corner or a dormant second floor into a high-functioning executive suite.
We handle the entire application process with the Markham Building Department, including all architectural and structural drawings. Our team has extensive experience appearing before the Committee of Adjustment for minor variances, ensuring your project moves forward without legal or bureaucratic delays. We ensure every inch of your addition complies with the latest Ontario Building Code safety standards.
We start with a detailed review of your property survey and Markham’s zoning bylaws to determine exactly what can be built. This step prevents wasted design fees and identifies potential hurdles with lot coverage or setbacks early in the process. We provide a preliminary estimate to ensure your vision aligns with your budget.
Our designers create detailed floor plans and elevations that blend the addition with your home's current style. We coordinate with structural engineers to ensure the new loads are properly supported, especially for second-story projects. This stage results in a full set of permit-ready drawings that meet all Ontario Building Code requirements.
We act as your authorized agent with the City of Markham, submitting all applications and responding to examiner questions. While the city reviews the plans, we finalize material selections and schedule our specialized trades to ensure a seamless start once the permit is issued. This proactive planning minimizes 'dead time' once the project begins.
Construction begins with foundation work and framing, followed by the critical 'tie-in' to the existing structure. Our site supervisors maintain daily presence to oversee inspections from municipal officials and ensure quality control at every phase. We finish with a meticulous walkthrough to ensure the new space is move-in ready and up to our 'Pros' standard.

Learn MoreBuilt By Pros completed a 1,200 sq. ft. second-story addition on our bungalow in Markham Village last year. Suzanne's design perfectly matched our 1950s brickwork, and the project was completed in exactly 18 weeks. The extra bedrooms and the walk-in closet they added have completely changed how we live in our home. Their site supervisor was on-site every morning by 7:30 AM, and the quality of the finish work on the new staircase is breathtaking.
We hired Ricardo's team to build a ground-level kitchen extension and a home office in Unionville. Navigating the heritage requirements was stressful, but Built By Pros handled all the city paperwork and got our permits approved faster than expected. The custom arched windows they installed in the new dining area are a neighborhood favorite. Despite the snowy weather during the January build, the team kept the job site clean and secure throughout the four-month process.
Our family needed more space in Cornell, but we didn't want to leave our great neighbors. Built By Pros designed a side-split addition that gave us a new master suite and a large pantry. They managed to tie the new dark siding into our original exterior flawlessly. The fixed-pricing contract was a lifesaver, as there were no surprise costs even when we decided to upgrade the bathroom tiles mid-project. Highly recommend their professional approach.
