The problem

Most pool houses get stuck before they're ever built.

Architects are slow. Generalist engineers don't know cabanas. Pool builders end up waiting months for stamped drawings while the deck sits empty and the homeowner gets impatient.

We fixed that by turning cabana engineering into a product, not a custom engagement. Three packages. Real timelines. One number to call.

The three packages

FAQ

Common questions.

Do you work outside Barrie?
Yes — anywhere in Ontario. Most of our cabana work is Muskoka, Simcoe, Kawarthas, and the GTA.
Do I need an architect too?
For Signature and most Estate builds, no. We handle the structural drawings the permit office needs.
What if my municipality has weird requirements?
We've stamped in 40+ Ontario municipalities. We know the quirks.
Can you coordinate with my pool builder?
Yes — half our cabana work comes through builder partnerships.
What about the bathroom plumbing and electrical?
Estate packages include coordination with your MEP. We can refer one if you don't have one.
How fast can we start?
Consults usually within 3 business days. Drawings start the week your deposit clears.
