The installation of the Lille Métropole commercial court on the ground floor of the Mercure tower follows the merger of the courts of Lille and Roubaix-Tourcoing. This rehabitation represents an urban, symbolic and functional challenge.
The location of this amenity contributes to giving an innovative momentum to the Union district as well as providing a new coherence to the 1970s emblematic architecture of Jean Willerval. Alongside the functional efficiency specific to this type of programme, there was also the need to fully preserve the existing façades.
This particular context provided the design grid, with the project strategy based on re-using the existing symbolic elements, either unchanged or as a support for new creations. The latter particularly led to the creation of vast patios drawing light into the heart of the building.
