Is an architect compulsory to build in Saint-Louis?
As everywhere in France, an individual building for themselves must use an architect once the floor area exceeds 150 m², counting the total after works for an extension. A company, including an SCI, always needs one for a building permit. The local rules for Saint-Louis (height, position, appearance) are set out in the local plan (PLU).
How much does an architect cost in Saint-Louis?
Fees are free and set in the contract. For a full mission, from design to site supervision, pricing guides usually quote 8–12% of the cost of the works excluding VAT for a new house and 10–15% for a renovation or extension. A mission limited to the building permit application is usually a fixed fee of about €1,500–4,000 excluding VAT.
Where can I get free advice before choosing an architect?
In most departments, the CAUE (council for architecture, planning and the environment) sees individuals for free, by appointment, to help them prepare their project. The map of CAUEs is on fncaue.com.
