The main objective of the proposal is to modify and to improve the current social, economic and technological condition of the “villas miserias”, the urban informal settlements in Buenos Aires, through the development of technological innovation processes. The principal strategies adopted are: the onsite production of raw material for building and construction, the development of building technologies using low and medium complexity processes to create new economic opportunities inside the formal construction market, the introduction of new building components to enhance the environmental sustainability and to improve the architectural quality of the existing “casillas”.
