The Assembly #4 - "Sustainable Architecture", organized by architect João Rebelo Costa, is the culmination of several moments of reflection held at vaga during the month of April, on ways of living and its sustainability, and has as its starting point the question: "is a sustainable architectural practice really possible?".

With climate change as the great challenge of this generation, everyone's involvement is essential: this is our biggest house, the planet that will be left to future generations and architecture cannot be alien to this collective challenge.
