State Council

Palais Royal, Paris, France - 2012

Built by Richelieu at the beginning of the 17th century, the state Council occupies the old Palais Royal. Restored over the course of centuries, the Palais hosts the works of Contant d’Yvry, Moreaux Desproux, Victor Louis, Percier and Fontaine, then Prosper Chabrol and the sculptor Pajou.

We have conducted successive works projects on the exterior and interior arrangements of the monument. Porchway, facades, roofs, library and auditorium, the whole monument has been restored.
