The French National Library was designed by Dominique perrot, a brilliant young designer who was deeply appreciated by President Mitterrand. The architectural design, interior decoration and furniture configuration of the museum are all contracted by the same company, and advanced science and technology are adopted to achieve harmony inside and outside.

The architectural design of the museum also reflects France's strong environmental awareness. Its earliest concept began with two leaves. There are no materials such as cement, tiles, lime, plastic, wallpaper, paint and coating from the outside to the inside. Walking around this library, you can see four materials: glass, metal, wood, red carpet, all walls or aluminum alloy or glass. The ground is all wood from outdoor to indoor, and most of the furniture is wood. Glass and metal materials give people a strong sense of modernity, while wood floors and forests make people return to nature. The exterior of these four buildings is glass. In order to protect books from sunlight, a movable wooden wall was added to the glass. Therefore, when the sun shines, the building becomes wood-colored, and when the sun shines, it is bright and transparent. All the wood used for the wooden movable wall on the building surface is imported from Gabon, and all the wood used for the square and indoor wooden floor is imported from Brazil.
