L’École Centrale de Lyon founded in 1857 and located near Écully Lyon is a University for engineering design. The aging restaurant in the school required renovation. This design mission was given to Sylvain ROUBAUD of cabinet JADE Architects in Villeurbanne with the aim of creating a warm and friendly environment. For this space with high ceilings the architect selected wood as the material choice for the ceiling as well as for the imposing wall on the mezzanine which creates the impression of a wooden cube. Using only a minimum amount of lighting fixtures and other elements in the ceiling the rich atmosphere of the design is preserved. The contribution of light through large bay windows provides a pleasant and relaxing atmosphere for the students .
