Designed in 1958, the CNIT is a mixed-use center (offices, shops, services), an emblematic building of Paris La Défense and an icon of modernist architecture. For the past 20 years,  Cro&Co Architecture has accompanied the transformation of the CNIT, adapting it to changes in its environment while preserving its identity.

In May 2024, to coincide with the arrival of the new Eole RER station in the CNIT basement, where up to 70,000 visitors per day will pass through, the team created new connecting spaces and a new shopping mall (45 shops over 9,000 m2).

For this restructuring, the team has developed :

- A high-quality range of shops and services, with exclusive brands (Toca Social, Aroma-Zone, Yann Couvreur Café...).

- An open, warm and luminous environment, incorporating noble materials (bamboo parquet), tempered lighting and natural light down to level -2...

- An intuitive user experience, highlighting the building heritage. The spindle lines of the Cnit vault are reproduced on the floors and ceilings of the lower level, to anchor the space in its context and guide visitors naturally.

- An exemplary environmental approach, with natural thermal regulation of the space without heating or air-conditioning. (BREEAM Excellent certification).

- A positive contribution to the region and its economy, with the creation of over 300 jobs.
