“…A series of general requirements has been proposed that the pop-up environments must have in order to respond to the most diverse needs, thus also indicating how they can have a positive and relevant impact in urban planning. Modularity [18,48,53,57], flexibility [18,48,57], speed [21,47,59] and simplicity of installation [18,47,91], economic affordability [21,47,57,80,91], constructive reversibility [47,54,57], and second-life management [47,[53][54][55]58] all derive mainly from the criteria for the design of temporary houses in case of natural disasters [5,8,11,48,53,54] but are also applicable for other types of pop-up environments. It has been seen how the use of pop-up environments has had a positive impact in the most diverse contexts that often represented a limit or a problem for urban planning due to their intrinsic nature.…”
