Method for the Design of Local Temporary Buildings to Ensure the Sustainable Development of the Liquid Society

“Liquid modernity” with its continuous and rapid change and the need to safeguard the environment, which is severely compromised by anthropogenic action, find an answer in local impermanence, that is, the art of designing and implementing man-made spaces conceived for a specific time, which arise from the peculiarities of the place, coexist in synergy with the local environment and return to it at the end of the time of use. A metabolism thought out at the design stage, in which the characteristics of compatible places are predefined for the “birth” and “death” of the building organism. The paper describes the method for the design and realization of local temporary building organisms, defining a three-stage process analysis of local potential, identification of requirements, design stage, guarantors of the compliance of the construction process with both the dynamic lifestyle of modern man and the sustainability of the intervention. The project is the result of analyses that start from the area allowing its promotion and sustainable development, and at the same time the environmental and economic cost of the building intervention is reduced. A benefit therefore for both the community and the individual, in a scalar and cyclical process guaranteeing that sustainable development capable of involving environmental, economic and social aspects. The methodology described is verified through a case study in the territory of L’Aquila (Italy): the design of a temporary building organism that can be used either to upgrade an existing building or in constrained or emergency contexts.
