Located on the Luxembourg-France border, the Belval building is a collaborative office development that responds to the rich industrial heritage of Belval, revitalising the area by making a positive contribution to the site and its surroundings. The scheme relates sympathetically to its neighbouring buildings and addresses the different characteristics of the principal axis of Porte de France on its eastern end and the Place de l'Académie to the west, while creating a green light-filled atrium that forms the social and environmental heart of the building.
