For their intervention, Sanaa decided to use acrylic to make transparent curtains. They imagined an installation design that left the existing space of Barcelona Pavilion undisturbed. The acrylic curtains are standing freely on the floor and shaped in a calm spiral. The curtain softy encompasses the space within the pavilion and creates a new atmosphere. The view through the acrylic will be something different from the original with soft reflections slightly distorting the pavilion.
