A word about the architect
Bouchaud Architectes is also known for its restructuring of the CB21 tower, several emblematic Haussmann buildings and the conversion of offices into a luxury hotel on Rue Pierre Charron.
For the architectural firm, the main challenge of this project was to create a visual link between the square in the heart of the block and the Parc Diderot in order to identify the main entrance. The design of the façade responds to the kinetic phenomena linked to its view from the circular boulevard of La Défense. The fifth façade is treated as a garden, accessible to employees, and protected from the wind by high guard rails.
