Why Add Instead of Move

Cheaper than a new house. Better than the alternatives.

$200K+

Saved vs. moving

Land transfer tax, real estate commissions, moving costs, and the inflated 2026 GTA price-per-sqft for established neighbourhoods make additions the cheaper math on most family homes.

12–18mo

Typical timeline

Realistic full-cycle: 6–10 weeks design + structural, 8–14 weeks permits, 4–8 months construction. We give you a written timeline before you sign anything.

+500–1500ft²

Typical added space

Most second storeys add 800–1500 ft²; rear extensions typically add 250–600 ft². Combinations are common and often the best math per dollar.

Common Questions

Before you book.

Rough 2026 GTA ranges: rear extensions $250K–$500K, second storeys $400K–$750K, full combination projects $600K+. Final cost depends on existing foundation capacity, structural scope, finishes, and permits. The free feasibility report gives you a written range, not a guess.

Most rear extensions and partial-second-storey projects can be lived in throughout, with construction sequenced to minimize disruption. Full second-storey rebuilds usually require 2–4 months of alternative housing. We map this out in the feasibility report so there are no surprises.

We handle Committee of Adjustment applications regularly across the GTA. A typical variance process adds 3–5 months to the timeline; we're realistic about your odds during the assessment and won't take a project where the numbers can't work.

Sometimes yes, sometimes it needs reinforcement. Our structural engineer evaluates this during the assessment — and if reinforcement is needed, we cost it transparently, not as a surprise mid-build.
