Quick answer
An architect in Paris costs 8–12% of the construction cost for a standard full mission, 5–8% for a partial or design-only mission and 12–15% for a complex one. A permit application on its own is quoted as a fixed fee: €3,000–€8,000 excl. VAT for a standard file, €8,000–€15,000 excl. VAT for a complex one.

Percentages apply to the construction cost excluding VAT, before technical studies, surveys, taxes and contingency. Final fees are set contractually once the brief, the existing building and the scope of the mission are known.

Why work with an HMONP architect

- Regulatory compliance (PLU, ABF, fire safety, accessibility)
- Optimised layouts that increase your property value
