One of the most original buildings in the business district, PB5 completes the Boieildieu island. The artwork of one of the most emblematic and atypical figures of the architecture of the Trente Glorieuse, the building is composed of facades animated by prefabricated panels close to bimorphism.
Originally entrusted to the Ducharme, Minost, Fischer and Kopniak team, the building was originally intended to be a hotel. Today, it is a Y-shaped office building with curved gables and black and white marble, echoing the CNIT just opposite. Its top two floors are treated in arcatures that are often missing from buildings. Finally, in order to absorb the variations in expansion, which fluctuate by 2 cm depending on the season, the building's 30,000 tons rest on 14 rollers.

A word about the architect

Originally from Turkey, Jean Balladur (1923-2002) began studying literature and was taught by Jean-Paul Sartre. He then turned to architecture and graduated from the Fine Arts Expert workshop in 1953.
In 1958, he signed with Benjamin Lebeigle and Jean-Bernard Tostivint the building that quickly made him famous: the offices of the Caisse centrale de réassurance in the 9th arrondissement of Paris. A fan of metal and curtain walls, he developed an aesthetic of concrete by creating the seaside resort of La Grande-Motte (1962-1991). The SCOR building (PB5) at La Défense, one of his latest projects, allows him to take a new approach that breaks completely with American models.
