French architects Ateliers Jean Nouvel and Belgian studio MDW Architecture have collaborated on designs for a new police headquarters on a former police cavalry site in Charleroi, Belgium, which now also accommodates a dance school. The Charleroi Danses occupy the two remaining wings of the cavalry buildings and will be extended as part of the proposals, while the 75-metre-high Hôtel de Police tower will be positioned between them. Although the retained buildings feature red brick walls, the new tower will have a tapered form constructed from blue engineering bricks.A public plaza will be created in the enclosed central spaces, while an adjacent series of smaller brick buildings will create studios for artists as well as dancers.
