We expect cities to be formally organized and regulated, especially when it comes to housing. Urban informality, however, is a phenomenon we are seeing in cities around the world. By definition, informal settlements are areas where houses have been constructed on lands without legal claim or occupancy. High prices, discrimination, etc. push people to these informal settlements, as they are left with little to no other options. These settlements are known to be unplanned due to not following the planning and building regulations. Not following these regulations can lead these neighborhoods to struggle with different issues, such as lacking basic services and infrastructures to name a few. In this special of Designing Cities For All, we aim not only to understand the city government ’s attitudes toward these informal settlements but also to explore what actions need to be taken to regulate and upgrade them. We will reflect on these topics with designers, urban planners, researchers, and practitioners.
