The informal city is a problem that could not be solved by the twentieth-century urbanism. It is necessary to produce a set of tools that will allow us to perform with solvency and responsibility in this area. Some of the tools of traditional architecture and urbanism can be successfully applied; others are yet to be elaborated. With this in mind, Drucker Arquitetura designed the winning proposal for the Sáo Paulo competition to rebuild the city’s slum-areas.
