The corporate headquarters of the Thales Group – the French company leader in high-technology fields such as aerospace, transportation, defence and security – has moved to the Carpe Diem tower in the La Défense business district of Paris.

The genesis of the project goes back to 2014, when Thales decided to leave Neuilly for the Carpe Diem tower, one of the most recent towers to open at La Défense, which meets the world’s highest environmental building and energy efficiency standards. The choice of the new Thales head office reflects the Group’s long-term strategy of growth and development and the enduring values and ambitions of a truly global organisation.


The challenge for Arte Charpentier Interiors was to create, within exceptionally tight deadline, an efficient, fully customized workspace designed for the 450 workers who settled in the Carpe Diem office, including a boardroom and a showroom for the company’s cutting-edge technology and expertise.

Thales wanted an open, collaborative space designed to foster focus, creativity and innovation. The concept developed by the architects is inspired by the values of the company and makes the head office a showcase for the Group’s global leadership.

Inside, the new working environment is designed around the communication of expertise within teams. The overall alignment with the tower’s existing architecture is reflected in the interplay of interrupted sightlines and broken lines evoking rupture, precision, and the creation new points of view and perspectives. It is a vector of internal and external communication, making it the master key to all of the Group’s activities.


The design was conceived as a comprehensive project to serve different functions: shared and closed offices spread over seven floors, with specialized spaces punctuating each level: reception, showroom, cafeterias, boardroom, president’s offices, clubs, etc.. . The broken line reappears on the floor and ceiling, as well as in the placement of lighting fixtures and the design of light grooves. The design is consistent from one floor to the next, one space to the next, contributing to the overall sense of the Group’s unity.

The atmosphere is minimalist and modern, featuring light colours, materials and textures that lean toward fluidity.


The execution of the project was made possible by the development of a precise, efficient methodology based on interviews and studio work on the part of the contractor, and through rapid, clear decision-making on the client’s part.
