What an architect costs, stage by stage

Fees explained in plain numbers, from the first sketch to the keys.

Printed fee report with a calculator, pen and glasses on a desk

Most people ask what an architect costs before they ask anything else. That is fair. Here are the numbers we work to.

Stage by stage

Site and brief is a fixed sum. Design, consent and details are a share of the building cost, agreed before we start drawing. Site visits are charged by the month.

What changes the figure

Listed buildings, steep sites and very small projects cost more per square metre. A clear brief costs less.

We put the whole fee in the first email, and we hold to it.
