Today, rapid urbanization and the accompanying rise in property values, as well as often politically motivated reassessments of local architectural histories, are leading to the disappearance of modernist buildings in cities around the world. This phenomenon can be observed in both Southeast Asia and Europe. Once case in point is the House of Statistics in Berlin. Although it was scheduled for demolition, initiatives rallied to save the historic building and spark public debate on the topic, making it possible to repurpose the site as a model project for the collaborative production of space, which is currently being implemented. But does it even make sense to conserve buildings that may already be architecturally outdated and (partially) dilapidated? According to which criteria should modernist buildings be preserved?
