Custom Home Additions & Multi-Story Extensions in Toronto & Etobicoke

Seamlessly Merging New Structural Engineering With Your Original Home

Building a residential extension requires a level of engineering mastery that goes far beyond standard interior remodeling. You are physically breaking into your home’s original structural envelope, pouring new foundations, tying into existing rooflines, and completely shifting structural weight loads.

At Procon General Contractors, we specialize in managing the complex design-build evolution of large-scale home extensions. Whether you are planning a multi-story rear addition to create an expansive main-floor family hub, or expanding vertically with a full second-story top-up, we handle the entire process. Because our owner Frank stays on your job site every single morning, we ensure your new foundation, framing, and mechanical hookups are executed flawlessly down to the millimeter.

The Extension Lifecycle: How We Build Your New Footprint

Achieving a flawless structural addition that perfectly matches your original home's aesthetic requires meticulous trade coordination. We manage every phase of the construction timeline:

1. Architectural Drafting & Committee of Adjustment Support

• The Process: Toronto’s density means additions often push the limits of local lot coverage, building heights, and setback bylaws. We coordinate closely with local architectural designers and structural engineers to draft compliant plans. If your dream layout requires a minor variance, we help guide your project through the City of Toronto Committee of Adjustment or Toronto Local Appeal Body (TLAB) process.

• The Result: Fully approved, legal, and code-compliant construction permits before a single shovel touches your soil.

2. Engineered Foundation Extensions & Footings

• The Process: A structural addition is only as safe as the ground it sits on. We manage the heavy excavation, install code-compliant soil-retention shoring if working close to property lines, and pour engineered concrete footings and foundation walls. We integrate robust weeping tiles, heavy-duty damp-proofing membranes, and a solid gravel base to protect against subterranean water penetration.

• The Result: A rock-solid, bone-dry foundation engineered to handle your new multi-story structure without settling or shifting.

3. Advanced Structural Framing & Roof Tie-Ins

• The Process: Tying a new extension into an older home requires precision carpentry. We shore up the original structure, remove exterior masonry walls, and drop in custom-engineered steel I-beams or structural laminated veneer lumber (LVL) headers to create wide, open-concept transitions. Our team frames the new walls and meticulously ties the new roof trusses into your existing roofline to guarantee a completely weatherproof seal.

• The Result: A structurally unified home with flawless interior transitions and a single, continuous, leak-proof roof system.

4. Comprehensive Mechanical & Thermal Integration

• The Process: Expanding your square footage puts a massive strain on your home’s original utilities. We evaluate your existing mechanical setups, upgrade your main panel to a modern 200-amp electrical service, and extend your plumbing stacks. To heat and cool the new zone evenly, we re-engineer your HVAC duct networks or install independent, high-efficiency ductless mini-split systems. We then seal the addition with premium spray-foam insulation to maximize energy efficiency.

• The Result: Year-round comfort, excellent energy efficiency, and modern utility lines seamlessly integrated with your original systems.

🏗️ One Major Project at a Time. No Sub-Contractor Gaps.

The biggest complaint Toronto homeowners have about major additions is seeing their project sit abandoned for weeks while the contractor juggles multiple jobs. Procon eliminates this entirely.

We focus exclusively on your property. Our owner, Frank, is physically on your job site every single morning supervising the foundation pour, checking the framing connections, and managing the mechanical rough-ins. Your home is never left vulnerable to the elements, your timeline is strictly protected, and your project gets our undivided concentration.
