While the mainstream view on the slums describes them as places to escape from and to destroy as soon as possible, more and more people look at slums in a different way. What if we analyze the slum and approach it as a self organized system that contains both flexible participatory input and a defined structure? Research on relocation of occupants of slums to housing projects shows that most of them are not satisfied with the move and would have preferred to have stayed in their homes. This means that people actually like to live in slums and there must be a reason for it. The squatter cities can teach us much about future urban living. (Brand 2010) An urban slum could be reviewed as an example of a structure that could be used while developing future projects. The purpose of this paper is to explore the positive aspects of slums and the lessons that can be learned from them. Is it worth it? Are there any real perspectives for slum structures?
