The interior designer is not authorized to intervene on the structures of the buildings, but he can call on a design office to deal with the structural part, if necessary. The law requires interior designers to have a decennial insurance.
Architect
The mission of an architect consists mainly in the construction, enlargement, or elevation of a building or in major renovations of buildings when the structure needs to be modified (floor, load-bearing walls to be consolidated).
