These glass boxes fulfil two architectural purposes, covering the building as well as connecting the inside and the outside. Lightweight, their architecture is like an apparition. We will place them at key points along the journey, and these boxes can be used to evaluate the orientation, exhibit objects and provide rest areas. During the visit, we will spark curiosity from the displays in the lobby. The visit chronology will be clearer. The rest areas can be enjoyed while having a coffee and taking in the panoramic views of the royal district and the historic monuments on the Paris skyline.
