Administrative center – Thiry Barracks

The rehabilitation of the Cité administrative de Nancy is part of a national programme to renovate administrative buildings in France. Architecturestudio’s mission is to transfer the services of the Cité administrative to the Caserne Thiry, a neighbouring building that has been renovated.

Covering an area of 17,000 m2, the project includes the rehabilitation of the two side buildings of the Thiry barracks, whose construction dates back to the 18th century, framing a Champs de Mars. The latter, open to Rue Sainte-Catherine, occupies a prominent place in the city with a surface area of 1.25 hectares. The programme responds to the need to enhance the value of the existing building, by respecting the building and its surroundings, while adapting the interior organisation of the preserved buildings to the new functions assigned to them.
Among the problems presented by such an old building, the main difficulty was the ability to solve the problems related to the lighting of the premises. The conservation and redevelopment of the landscaped areas, including the Place d’Armes, are also the major elements of this major rehabilitation project. As soon as they enter the Cité administrative, visitors are directed to the various buildings by clear signage and access them in their central part.

The project retains the existing partition walls, which are partially open in order to free up the floors and the interior space, as well as the staircases. The walls bordering the central circulation will be demolished in order to guarantee the flexibility of the layouts and the contribution of natural light in the central part. The main objective is to preserve and enhance the existing bays. The programme also includes a strong reuse approach: interior and exterior joinery, flooring, false ceiling tiles, switches, radiators, sanitary equipment, etc. In addition, the rehabilitation of the Cité administrative will involve close collaboration with numerous local companies: France-Lanord & Bichaton, KELLER, LORRY, ppe, Vibrac, Lagarde Meregnani, Réciprocité and AJir Environnement.
Finally, the architectural proposal takes into account the evolution of working methods over time. The central space is freed up and becomes an active strip that integrates the proximity services necessary for each entity: reprography spaces, proximity archives, dead archives, etc. This active strip will become an open space with the possibility of being used as an office. This active strip will become a multifunctional open space and will host convivial activities, informal work spaces, a reading area, telephone booths, etc.
