The International Architecture Biennale became the reason to rename the WTC I tower in Brussels' Noordwijk from a World Trade Center into a World Transformation Center. Artists, students, architects and many others temporarily occupy the office tower, which symbolizes the megalomania of twentieth-century consumptionism. Paradoxically, this place temporarily transforms into a new epicenter to develop concrete actions for a new and sustainable future. Among other things, the 'Proeftuinen Ontharding’ (Unsealing Testing Grounds) project, a transition program aimed at removing concrete, asphalt and buildings, sees the light of day here.
