Custom Home Additions & Extensions
Whether you need to build out or go up, Procon delivers expert architectural integration, structural integrity, and premium finishes. Serving Toronto, and Etobicoke.
A home addition is one of the most complex residential projects you can undertake. It is not just about adding square footage; it is about seamless structural integration with your existing home. At Procon General Contractors, we specialize in custom home additions and extensions that feel like part of the original design, not an afterthought.
Because we manage only one project at a time, you get the direct attention of our owner, Frank, who is on-site daily to monitor the foundation, framing, and structural transitions.
Vertical vs. Horizontal Expansion
Horizontal Extensions
Perfect for families needing more main-floor space. We specialize in rear and side home extensions, including kitchen expansions and open-concept great rooms. We handle the site excavation, foundation requirements, and full integration with your current floor plan.
Vertical Additions
Expanding upwards is the ultimate way to increase your property value without losing backyard space. We are experts in second-story additions, requiring precise structural engineering and load-bearing reinforcement to ensure your home’s foundation can support the new level.
Why Trust Procon with Your Addition?
Architectural Synergy:
We ensure your new extension matches the existing rooflines, brickwork, and interior aesthetics of your home.
OBC Compliant:
From zoning permits to Committee of Adjustment meetings, we handle the legal complexities to ensure your addition is 100% compliant with the Ontario Building Code.
Structural Integrity:
Whether it's reinforcing existing footings for a vertical addition or pouring new ones for a horizontal extension, we never cut corners on what lies beneath the surface.
Single-Site Focus:
We do not juggle multiple jobs. When we start your addition, your project is our only priority until it is complete.
Navigating Toronto Zoning & Building Permits
A major home addition is a significant investment, and the City of Toronto’s regulatory landscape can be complex. You don't want to leave your project’s success to guesswork. At Procon General Contractors, we take the stress out of compliance by managing the entire regulatory process from start to finish.
Our permit and zoning management includes:
Zoning Bylaw Assessment:
We evaluate your property’s specific zoning constraints—such as floor space index, setbacks, and height limits—to ensure your addition is feasible before we break ground.
Permit Application & Management:
We prepare and submit all necessary documentation to the City of Toronto, including architectural and structural drawings required for building permits.
Committee of Adjustment Coordination:
If your project requires a minor variance, we provide the technical expertise and documentation necessary to represent your interests and streamline the approval process.
OBC Compliance:
Every addition we build is strictly monitored to meet or exceed Ontario Building Code (OBC) standards. We coordinate all mandatory city inspections, ensuring your new space is safe, legal, and adds certified value to your home.
Why this matters: A permitted addition is not just a legal requirement—it is your protection. Proper permitting ensures that your project will not face future insurance issues or complications when it comes time to sell your home. When you work with Procon, you aren't just getting a builder; you are getting a partner who protects your asset.
Local Expertise: Serving Toronto’s West End & Etobicoke
Every Toronto neighborhood has its own architectural character and set of zoning challenges. Because we focus exclusively on the West End, we understand the specific nuances of your local property. We don’t just build additions; we seamlessly integrate them into the history and style of your home.
Our local focus includes:
The Kingsway & Etobicoke:
We specialize in preserving the timeless aesthetic of historic home foundations while retrofitting them with modern structural reinforcement. Whether you are dealing with mature lots or unique brickwork, we maintain the integrity of your property’s original charm.
High Park & The Junction:
These areas require creative solutions for tight urban lots. We excel in vertical additions and strategic rear extensions that maximize every square foot of your property without compromising your outdoor living space.
Bloor West Village & Swansea:
We have extensive experience navigating the specific setbacks and committee-focused requirements common in these established neighborhoods, ensuring your project meets local bylaws and neighborly expectations.
Rexdale, Mimico, & Beyond:
From basement underpinning to complete second-story additions, we bring professional, owner-managed general contracting to families looking to grow in place.
Why local matters: We know the soil conditions, we understand the typical foundation structures of homes built in these eras, and we know how to navigate the local inspection offices. When you hire Procon, you are hiring a neighbor who understands the specific landscape of West Toronto construction
The "Addition" Checklist
Building an addition isn't just about building; it's about planning. We guide you through:
Feasibility Study: Can your lot and current structure support the expansion?
Permitting & Zoning: Navigating the Toronto city bylaws for setbacks and height restrictions.
Foundation Assessment: Ensuring the ground can hold the load of a new floor or expanded footprint.
Integration: Electrical, HVAC, and plumbing upgrades to support your new square footage.
Frequently Asked Questions About Home Additions
How long does the design and permit process take in Toronto?
For most custom additions, the design and permitting phase can take anywhere from 3 to 6 months. This includes architectural drawings, structural engineering, and navigating the City of Toronto’s zoning bylaws or Committee of Adjustment. We manage this timeline proactively to avoid delays, ensuring that once we break ground, the process moves efficiently.
Will we be able to live in our home during the construction?
In most cases, yes. We prioritize site safety and cleanliness, sealing off the construction zone to minimize dust and noise. However, for major structural integrations (like removing exterior walls for a rear extension), there may be a short period where certain areas of your home are inaccessible. We will discuss this during the planning stage so you can plan accordingly.
Does a custom addition require a new foundation?
It depends on the scope. A horizontal extension usually requires a new foundation, while a vertical addition often requires reinforcing your existing foundation to carry the new load. As a structural specialist, Frank assesses your home’s current foundation early in the feasibility stage to ensure your home is built on a solid, code-compliant base.
How do you handle the disruption to our daily routine?
Because we only take on one project at a time, you have the full focus of our team. We maintain a strict daily schedule, keep the site organized, and ensure that our presence is as non-intrusive as possible. You won't be left wondering when a crew will show up—we are there, on-site, every day until the job is done.
Why is it better to build an addition instead of moving?
Moving in Toronto involves significant land transfer taxes, real estate commissions, and the stress of finding a new home that matches your needs. A custom addition allows you to stay in the neighborhood you love while gaining the exact square footage and functionality you need, ultimately increasing your home’s equity far beyond the cost of the renovation.
