The concept design for the shopping mall of Piazza D’armi in Ancona stems from the concept of freeing the space at zero altitude, altitude of the actual square, and the concept to create the underground shopping mall in order to generate a large public space on the surface accessible to all with green spaces and sports spaces and a large square from which through the glass and steel entrances you can access the underground stores. An ambitious project that FIMA has created for a project financing of the city of Ancona.
