New build · Canada
Cost to build a house — from spec build to architect custom.
Plug in the square footage and the build quality. We work out the framing-and-finish cost, then add the bits people forget — basement, garage, lot servicing, design fees, development charges, permits and tax — for a real all-in budget.

// note Estimate only. Toronto/Vancouver builds run 25–40% above national averages. Self-built (acting as own GC) can shave 10–15% but adds risk. Development charges vary wildly by municipality (Toronto inner ~C$50k; smaller towns can be C$5k). New homes under C$450k may qualify for the GST/HST New Housing Rebate — not factored here. Confirm with your builder.
