How it works
A concrete tool, grounded in French planning law
4-question diagnostic
Person type, project, area, zone: we compute the applicable permit and processing time.
R*431-2 compliant
Our logic mirrors the French Urban Planning Code and flags cases where an architect is mandatory.
Detailed guide
A pillar article complements the tool: thresholds, deadlines, third-party appeals, professional specifics.

Why 4 minutes instead of a contact form?
Because the person who calls you back is not a salesperson — it is the architect who will draw your project. We want to understand before we propose a meeting, not the reverse.
We answer personally within 24 working hours. Phone, short video call, or voice note — your choice.
