Building a custom home is a longer commitment than most people expect going in. Planning for the real timeline — and understanding where the time actually goes — is the difference between a smooth project and a frustrating one.
The short answer
Most GTA custom homes take 12 to 18 months from the first design conversation to the day you get your keys. Complex projects — difficult lots, major variances, or very large homes — can run two years or more.
| Phase | Typical duration |
|---|---|
| Design & engineering | 2 – 6 months |
| Permits & approvals | 1 – 4 months |
| Construction | 6 – 12 months |
| Total | 12 – 18 months |
Where the time goes
Design & engineering (2–6 months)
Turning your vision into a buildable, engineered set of drawings. The more decisions you make early and firmly, the faster this moves.
Permits & approvals (1–4 months)
A straightforward building permit is the quick end. If your design needs a minor variance, expect longer — in Toronto, a Committee of Adjustment hearing is typically three to four months out from a complete application, followed by a 20-day appeal period before the decision is final.
Construction (6–12 months)
Excavation and foundation, framing, mechanical and electrical rough-ins, then the long finishing stretch — where quality and sequencing show.
What adds time
- Variances, heritage review, or conservation authority approvals
- Servicing, utility relocation, or difficult site access
- Changes made mid-build — the most common self-inflicted delay
- Weather, and material or trade availability
How we keep it on schedule
We work the engineering and approvals out early, lock selections before they hold up the trades, and keep one dedicated team on your build from start to finish — so nothing stalls waiting on a hand-off.
