L’Atoll Angers shopping center is divided at each end by 4 large corridors, like four entrances. The building is covered with a large amount of aluminum veneer material, with backlighting. The shell of the building is 8 to 12 meters away from the main structure, protecting the shops behind and keeping the transportation carried out by these shops out of the sight of the guests walking in the Atoll center, providing a free passage for security services. The covering shell extends from the inside to the outside, along the corridors to the roof, forming a partial canopy for the corridors.
