Question 1
Building permit or prior declaration?
It depends on the floor area and on how long the home stays in place. Below certain thresholds, a prior declaration is enough; above them, a building permit is required.
The planning department of your town hall confirms which procedure applies. Service-Public.fr details the floor-area thresholds.
