In a particularly vulnerable context such as Spain, the effects of climate change are no longer a distant threat, but a reality that must be faced every day. Therefore, the design of architectural devices capable of adapting cities to environmental factors is a priority that must be taken into account. This thesis work identifies this need as an opportunity to rethink the public space of cities, and vice versa, investigating how this relationship can be translated into occasions for projects at the urban scale. The issue of climate change is therefore addressed in a proactive and broader way than the current trends, that see it as a simple problem looking for a solution, placing mankind and the way people live the spaces of cities at the center of the debate.
