The reversible city is a temporary land occupation project. The workshop provided for the arrangement of the services relating to the archaeological park of Selinunte. The objective and themes of the work were on the one hand the integration with the landscape and on the other the design of ephemeral, mobile architectures, which found the essence of their design in their temporariness. Some prototypes have been created, designed with simple and economical technologies, based on a structural system in steel boxes mounted on a trolley on wheels approved for road transport. The main module constitutes a transportable power plant, based on a system of photovoltaic panels that powers the other modules. The second module represents the infrastructures, bathrooms and kitchens, designed as compost toilets and disposal systems sized to be contained within the module. Finally, there are the collective services, represented by a panoramic module that frames the landscape and the residential module, conceived as minimal accommodation, but extra-luxury accommodation, which can be hidden in the landscape and find the measure of quality in the landscape itself.
