In the interior design project for the Paris headquarters of the international law firm Norton Rose Fulbright, the above is at least as interesting as the following... Because before the design process was launched and then implemented, a decisive game was played between the partners and Chambers architects. The seemingly straightforward decision to remain in the building rather than abandon it was an extremely complex one, with far-reaching consequences for the firm. In fact, it marked the beginning of the collaboration and largely built the trust that characterized it thereafter. The vast headquarters could no doubt easily absorb the current growth in headcount, but it did have a few drawbacks, including an understandable feeling of weariness when other competing location hypotheses shared the appeal of the new. However, an initial benchmark covering organizational, financial and planning aspects ultimately led the lawyers to decide in favor of the current site. An address revisited through designers' proposals and re-enchanted in the eyes of users! Contrary to the original reservations, the building at 40 rue de Courcelles (Paris ^8th) turned out to be an address with a bright future, where the company's developments, known or hypothetical, would benefit from the most flexible and suitable framework.
