How architect fees work — and when you pay

Percentage, fixed or hourly — how they differ, and why payments should follow delivered work.

Floor plans on a laptop screen and printed sheets on a desk

The first thing most homeowners ask is the fee. The answer depends on how the studio charges and what scope you hire it for.

Three common methods

A percentage of build cost suits new houses; a fixed fee suits clearly defined extensions; hourly suits advice and site visits.

Pay for delivered work

Good instalments are tied to real deliverables — concept, permit set, construction set — rather than a large advance, and always paid to the company account with a receipt.
