The main assumption to design the pavilion of the Architects of Bergamo at the fair Edil 2013 was the prevalent use of alveolar polycarbonate panels produced by Rodeca Italy, sponsor of the intervention. From here came the idea to use a product to achieve a two-dimensional monolith translucent, from some points of view that is very stiff and smooth, while other is jagged and undefined. A volume in which you can enter, changing, evanescent, but at the same time very material, in fact, mono-material. From the constructive point of view the pavilion is achieved by overlaying polycarbonate panels resulting from production rejects united with common metal clasps. Each clip, with a label with the logos of sponsors indicated, can be extracted from the visitor becoming an advertising gadget.
