Architecte in Paris 75020

The agency supports both private and public project owners in restoration, rehabilitation, transformation, and extension projects when a building requires in-depth understanding before any intervention. Old houses, mansions, apartments located in heritage buildings, annexes, rural buildings, protected monuments, or complex sites: every place has its own history, construction logic, and fragilities, which SCALA Architectes Associés carefully analyzes with precision.
