Installing the C100 armchairs in the sophisticated auditorium of the CB21 skyscraper found in Paris’ La Défense business district

221 seats find pride of place in an exclusive yet minimalist space, housed in an ever-up-to-date building


This 188-metre-high steel and glass high-rise building was built in the 1970s, yet is constantly evolving to keep up with the times and changes that impact the way we live and work. The place is famous: the office tower stands at the gates of the Ville Lumière (aka. Paris), in the La Défense business district. The building has recently undergone a major renovation project, commissioned by one of the main players in European real estate, Covivio.

The transformation incorporated no less than 14 floors and was based on the design presented by Bouchaud Architectes, a firm entrusted with the task of restoring prestige to the auditorium. To entice users towards its spaces, the French studio’s interior design group also created an ad hoc library. 221 Baldanzi & Novelli-designed C100 armchairs were installed to fill the auditorium’s customised layout. The seats promptly responded to the project’s needs, which focused on attention to detail, a minimalist style, natural-hued materials and the creation of an exclusive space, connected and equipped with the best audio-video technologies.

The highly customised linear C100 models were arranged in straight rows on a partially sloping surface. The final approved design was the fully padded version with a low backrest, faux leather covering and graphite-coloured painted frame. Furthermore, the sides house large tip-up writing tablets and electrical sockets.
