Home Additions & Extensions
More space without moving. Toronique designs and builds home additions that integrate seamlessly with your existing structure, your neighbourhood, and your budget.
Expand Your Home Without Leaving the Neighbourhood You Love
Toronto homeowners regularly face the same decision: outgrow the house or move. Moving means competing in one of Canada's most expensive real estate markets, uprooting your family, and starting over. An addition lets you stay where you are, invest in the property you already own, and build the space your life actually requires.
Toronique has been building home additions across Toronto and North York for over 20 years. We understand how to work with existing structures, navigate the city's zoning bylaws and Committee of Adjustment process, and deliver an addition that looks and feels like it was always part of the home. Our team manages everything: architectural coordination, permits, structural engineering, construction, and finishing.
Like every Toronique project, your addition comes with a guaranteed flat-rate price and a guaranteed completion date. You'll know the full cost and timeline before we start, so you can plan around it with confidence.
Types of Additions We Build
Second Storey Additions
The most popular addition type in Toronto, especially in North York where bungalows on generous lots are prime candidates. We add a full second floor to your existing home, including new bedrooms, bathrooms, and living space, while reinforcing the existing foundation and structure to carry the added load. The result is a home that doubles its usable square footage without touching the lot footprint.
Rear & Side Extensions
Extend your home outward to create larger kitchens, expanded living areas, or new main-floor rooms. Rear and side additions work well on properties with setback room to spare and are often the fastest path to meaningful extra space. We manage zoning compliance, neighbour notification requirements, and structural tie-ins to ensure the extension integrates cleanly with the original structure.
Above-Garage Additions
The space above your garage is often the most underutilized area of your property. We convert it into a bedroom suite, a home office, or additional living space by reinforcing the garage structure, adding proper insulation, HVAC, and egress, and finishing to match the rest of your home. It's one of the most cost-effective ways to add livable square footage.
In-Law Suites & Secondary Units
Toronto's evolving housing policies have made secondary suites and in-law suites more accessible. Whether you're adding a self-contained unit for an aging parent, an adult child, or rental income, we build these spaces to meet all code requirements for separate entrances, fire separation, and independent mechanical systems.
Why Toronique for Your Home Addition
We Know Toronto's Zoning Inside Out
Additions in Toronto are governed by a complex web of zoning bylaws, setback requirements, height limits, and lot coverage rules. Many projects require a minor variance through the Committee of Adjustment. We've been through this process dozens of times across North York and the city, and we know how to prepare applications that get approved without unnecessary delays or redesigns.
Structural Integrity Is Non-Negotiable
Every addition puts new demands on your existing home's foundation, framing, and systems. We work with structural engineers to assess load capacity and design reinforcements before construction begins. This isn't an afterthought in our process; it's the starting point. An addition that compromises the original structure isn't an addition, it's a liability.
Seamless Integration, Not a Bolted-On Box
The mark of a well-built addition is that nobody can tell where the original home ends and the new construction begins. We match rooflines, exterior cladding, window proportions, and interior finishes so the addition feels like it was always part of the home. That attention to continuity is what protects your property value and your curb appeal.

Frequently Asked Questions
Home additions in Toronto generally range from $250 to $500+ per square foot, depending on the type of addition, structural requirements, and finishes. A second storey addition on a typical North York bungalow often starts around $350,000 and can exceed $600,000 for larger or more complex builds. We provide a guaranteed flat-rate price before construction begins.
Most additions take between 5 and 8 months from the start of construction. The permit and design phase adds another 3 to 6 months depending on whether a minor variance is required. We include a guaranteed completion date in every contract.
Yes. All home additions in Toronto require a building permit from the City. Many also require a minor variance application through the Committee of Adjustment if the proposed addition doesn’t fully comply with existing zoning bylaws. We manage the entire permit and approvals process on your behalf.
In most cases, yes. For rear extensions and above-garage additions, you can typically remain in the home throughout construction. Second storey additions may require temporary relocation during certain phases, particularly when the roof is open. We’ll give you a clear picture of what to expect during our initial consultation.
For most Toronto homeowners, a second storey addition is one of the highest-return investments you can make. It can double your livable square footage without increasing your lot footprint, and the added value typically exceeds the cost of construction in established neighbourhoods like North York, Leaside, and East York. It also lets you stay in the neighbourhood you’ve chosen rather than competing in the resale market.
