Rehabilitation, modernisation and urban integration of the Saint-Louis Market Hall, originally built in 1953, with the aim of revitalising the town centre: a “City Centre” regeneration project.

The hall accommodates a gourmet food market as well as a welcoming, open and inclusive space for events and activities—multifunctional and creative—offering modular internal spatial layouts adapted to both day-to-day operations and event programming.
The hall benefits from outdoor extensions that echo the interior programme. Reversibility and flexibility are the guiding principles of the project.

The hall, emblematic of the post-war reconstruction period, is the core value consistently highlighted by the project. Our approach is based on the preservation and enhancement of the existing building, through a threefold strategy:

- visual enhancement, as the project does not obscure the reading of the repetitive concrete structures, but seeks to reveal their plastic qualities by reworking the underside of the roofs to restore a legible and high-quality material expression;
- volumetric enhancement, as the project frees up views and amplifies the scale of the building;
- enhancement of the building’s structural and technical achievements, through respect for the original static system. Suspended elements are limited to lighting and acoustic components, allowing the technical feat and the resulting architectural performance to remain clearly legible. We propose a harmonisation of the exposed concrete surfaces and the lighting of the roof structure to reveal the finesse and richness of its design.
The vast interior volume, entirely free of intermediate supports and exceptional both in scale and in the quality of natural light, must remain the hall’s defining architectural feature, generating a powerful and spectacular effect. The project is committed to revealing the clear and strong identity of this remarkable place.
