São Paulo is the financial center and largest city of Brazil, and victim to a seemingly unending water crisis. The situation stems from over-populated neighborhoods lacking in a regulated infrastructure, with buildings that are uncoordinated in their development and maintenance leading to pollution in nearby water reservoirs. In 2009, the government of São Paulo sought to address this issue by expropriating the homes of 200 families, who were then moved back in 2012 to a new construction designed by Hector Vigliecca; the Novo Santo Amaro V Park Housing.
In this video from The Architectural Review - which supports their full building study - Vigliecca and current residents of the complex reflect on what the valley of unregulated infrastructure used to be like, and how it has developed to the present day.
