After an initial construction of 1800 seats of modular stands in 2010, Alcor Equipment carried out numerous extensions at the USON Stadium (Fédérale 1), making it a stadium with a strong modular emphasis.

The 1800-seat stand was expanded to 2200 seats, and thanks to the installation of gantries at the back, spaces under the stands were created (refreshment stands and restrooms). Spectators thus have access to these services without leaving the stand. The capacity of this stand will be quickly increased to 3000 seats, with the Alcor Equipment modular stand system allowing for simple scalability.

The official stand, built using traditional construction methods, was extended on both sides with 2 x 400-seat extensions; these extensions, made of modular stands, feature facilities on the ground floor (Bodega, gym) and luxury boxes on the top floor. These extensions are connected to the central stand, giving the appearance of a homogeneous ensemble.

Finally, a two-story structure was built behind the try line (lounges, restaurant, bar), offering a magnificent view of the field.

All of these works were overseen by the Quatro Architecture firm in Vierzon.
