The project consists of the transformation and renovation of a former bank to accommodate a set of offices. Marked by a cruel lack of natural light, the project proposes the creation of an atrium in the center of the building allowing to open the trays but also to provide a diversity in the spaces. As a result, the circulations are distributed centrally and grouped around the atrium by a system of bridges. All floors are flexible to best meet the evolution of the company either in terms of number of workers or in the diversity of spaces required.
