This assignment pursues the transformation of a modernistic tower (1969) in the centre of Brussels from a unilateral office building into a multi-faceted construction with added public value. The renovation has become a catalyst for creating a pedestrian zone that connects public spaces in the area. The building is being transformed from a heavy, black box into a bright, transparent and inviting construction. The ambitions for MULTI (the new name for the Brouckère tower) include current and relevant projects, pursued through a thorough investigation into spatial and social context. By understanding the current role and the potential of the building, the new project has been proposed as an ‘Urban Platform’. The project serves as a connection between the different surrounding neighbourhoods.
