WeWork is an American firm providing premises and co-working services, which arrived in Paris in 2017. The 92 Champs-Elysées was WeWork’s fourth address in Paris and the firm’s first cooperation with Quadrilatère, which is this year developing the new site on Rue Jules Lefevbre in the 9th arrondissement. With the opening date scheduled for 1 June 2018, WeWork’s project demanded a sustained pace, with development and works being completed in just 13 weeks. We faced two other challenges: difficulties accessing the Champs-Elysées; and the ground floor stores that continued to open throughout the work. Owing to its prestigious location, the Champs-Elysées WeWork site features very high-quality fittings with lighting and acoustic standards exceeding those normally applied in co-working facilities. Lastly, the play on materials required extensive consolidation work to carefully integrate the various elements.
