¿Adónde van los edificios cuando mueren?

This article proposes a circular perspective to understand architecture, which means that the design process must keep in mind the reuse strategies at the end of the life cycle, in order to avoid its “death”: an inefficient demolition of the building. We approach the problem from two different viewpoints: biodegradable architecture, in which the natural components follow the natural flow and return to the system by their degradation into nature; and design for disassembly, in which the building’s compo-nents are dismantled in order to be reused. The article argues that it is possible to explore new ways of pursuing sustainability in the built envi-ronment by opposing these two perspectives.
