Dating from the 1930s, the Bourg-la-Reine barracks was rebuilt and expanded to meet the brigade's current needs. Located on the edge of the city center, it respects the typology of the neighborhoods it adjoins, with a compact street frontage on R+3 facing a boulevard equipped with several public facilities and, in the depth of the plot, a R+1 building in harmony with the residential sector which surrounds it. On the boulevard side, where the exits take place, the building groups together the barracks' activity and storage premises, the firefighters' accommodation and the offices. Along the central exercise yard, it lowers to house the gymnasium and is closed by the instruction tower. At the back of the plot, the R+1 houses the rest and dining areas. This "domino" organization makes it possible to limit nuisances to residents of the residential area and to ensure the confidentiality and security of the barracks' activities.

The reconstruction is part of a high environmental requirement. It relies in particular on the reuse of the original stones (which cover the new foundations) and on a wide use of wood, which makes up the superstructures of the buildings and has made it possible to face the constraints of a construction site on an occupied site, with little storage space for materials. Kerto® LVL laminated veneer lumber plays a key role in the construction choices of the project: it constitutes the frame portals as well as the roof boxes in the form of Kerto® Ripa ribbed panels, prefabricated to measure and installed immediately after their delivery using a tower crane. It is accompanied by CLT floors. Kerto® LVL also covers the facades, through sunshade grilles and fins, protected by zinc on the edges. With its great rigidity, it helps to give finesse to the architectural style of the structure.
