The Monnaie de Paris museum underwent a complete renovation. The project took 6 years and the result reflects that investment. Its majesty merits discovery. Selected from a public call for tenders, Prugent Diam Europe formed a team exclusively dedicated to this project. The company managed the sub-trade contracts of the boutique’s shopfitting (350 m2), furnishings, and was also involved in the site’s architectural planning. The designing of this building required a close collaboration between teams from Prugent Diam Europe and the Monnaie de Paris museum. Visiting the Lannemezan site permitted the furnishings to be tested before shipping and the lighting to be fine-tuned, which varies according to each window display. Important security regulations, different for each exhibited article, are also verified on-site.
