If you're a homeowner in Toronto or anywhere in Ontario and you're thinking about renovating — whether it’s adding a second floor, building a rear addition, or creating a garden suite — it can be hard to know where to start.

Do you call a contractor? Do you draw it yourself? Do you get a zoning certificate?

What many homeowners don’t realize is that what happens in the early phase of design — before you hire trades or start drafting construction drawings — has the biggest impact on your timeline, cost, and long-term value.

1. Zoning Surprises Are the #1 Reason for Delay

Even if your home “looks like others on the street,” your proposed addition may not be allowed — or it may require a lengthy approval process.

Side yards, building height, lot coverage, and angular plane rules all affect what you can (and can't) build.

A zoning-informed sketch early on can save you months of rework and thousands in redesign fees.

2. Additions Are About Space — and Flow

Adding more space isn’t just about square footage — it’s about how your home functions. A poorly placed stair, cramped corridor, or unusable nook can make an expensive addition feel awkward or disconnected.

In the early design phase, we sketch multiple options that test light, movement, and family flow, all before investing in engineering or permit drawings.

3. You Might Have More Options Than You Think

In Toronto and many Ontario municipalities, recent zoning changes allow for laneway suites, garden suites, and even duplex or triplex conversions on many lots.

With the right layout and site strategy, you may be able to:

• Add a second unit without touching your main home
• Convert a basement legally
• Increase resale value and income potential

These opportunities are often missed when you start with a contractor or skip the design thinking step.
