Double Your Living Space Without Moving

Every project is unique.

Frequently Asked Questions
Can my house support a second story?
Most well-built homes can, but some require foundation or structural reinforcement. We assess this during our free initial consultation — no surprises.
Will it match my existing home?
Absolutely. We design additions that look like they were always part of your home — matching rooflines, siding, and architectural details.
How long does it take?
Typical timeline is 6-10 months: 2-3 months planning/permits, 3-5 months construction. We provide realistic timelines upfront.
Do I need to move out?
During roof removal and framing (4-6 weeks), temporary relocation is recommended. We’ll discuss options during planning.
Do I need a variance?
Toronto has height restrictions by zone. We research your property’s zoning and handle Committee of Adjustment if needed.
Do you handle permits?
Yes. We manage all permit applications, engineering, and COA hearings. 43 years of experience with Toronto’s building department.
