Framed by two “traditional” Parisian structures, the building to be rehabilitated is distinguished by its understated opulence. Abutting the planned construction, it lays the foundations for the emerging architecture. Thus, instead of a superimposing itself, the new building fits harmoniously to form a sober and protective extension. Prolonging what is there, the extension is delicately placed on the last existing level. Seeming to levitate, it detaches itself from this “pedestal” by a linear hollow joint forming an almost invisible link between the two entities. Simple and regular, the volume does not impose itself on the other, but rather reveals its value, by crystallizing their relationship. On the courtyard side, the building does not occupy the entire available volume; it is sculpted to fit coherently with the adjoining structures, and to benefit its users by minimizing the impact on the neighborhood. Urban and contextual, the forms take up the allotted space by continuing the existing inner courtyards. Solid and refined, they reinterpret the molding of industrial facades in a contemporary way. The internal organization retains elements that comprise the essence of the existing structure, making use of the building’s potential so that it can be used and appreciated as it was originally designed.
