This research project investigates the way in which subjectivity takes control of public space in the form of residual buildings. In order to open a perspective on the difference between a traditional space organization that is shaped out of contingent needs and urban territories which are built upon institutions, administrations, rules and information facilities, The City of Migration – or of Collapse investigates Zeytinburnu where the numbers show 60% of buildings should be demolished – not only because the city is going through a renovation process while eradicating 70% of the buildings which are in violation of zone permits or even not, but these buildings are in high risk of decay and could collapse any time. Eventually, using the post-it metaphor, the study of these buildings overlaps with the characteristics of the project: dually temporary, having been built out of personal needs in unsuspected lands and absorbed and adapted into urban regulations.
