The project was developed as part of a public-private partnership (PPP) process initiated by the City of Differdange in Luxembourg for a grandstand building and a parking garage at the Parc des Sports sports center. The design concept seeks to respond to the themes of movement and leisure while integrating playfully into the urban context.

A rectangular floor plan was chosen for the grandstand building. It presents a closed façade toward the street to the south and opens toward the playing fields to the north. To strengthen the dialogue between the foyer and spectator areas of the grandstand building and the public square, the previously closed façade on the entrance side was transformed into a louvered structure. This allows the building to retain its clear geometry without constricting the urban space, while simultaneously opening up visual connections between spectators and the surrounding city.
