- Updated on
- La rédaction
The short answer
For architecture and interior design, the regime is: regulated profession or activity. The decisive points are: qualifications and professional body, the legal form (sole trader or SL) and the steps specific to the activity. A company set up by a non-resident first goes through foreign investment authorisation.
