This is an intervention in a well-known shopping center in Barcelona whose transformation was to visually unify all the shops facades and to design new lighting system. It is fixed in each of the hollows of the lattice grid and creates a visual light mesh. At the hollow of the Mall (the heights where we located this illumination) it has been created a double facade in translucent microcellular polycarbonate to hide the small turbulences inderictly caused by each shop.
