This Project was developed for the international architecture competition promoted by IaaC- Institute for Advanced Architecture of Catalonia, on the theme of “The Self-sufficient City: Envisioning the habitat of the future”. The aim of the contest is to generate insights and visions, ideas and proposals that help us envisage what the city and the habitat of the 21st century will be like. I designed a self-sufficient house powered by green energy for a couple living in the year 2020 in Sao Paulo, Brazil, though the project can be adapted to any world location
