“Every city takes its form from the desert it opposes.” Italo Calvino, Invisible Cities, 1972. Nomads say there is no memory on the surface of the desert. You have to dig. A discovery shared with my father in 2002 in the North African desert: a Paleolithic cave. A treasure trove of paintings, graffiti, and artifacts buried by the sand. The memory of that discovery brought back an idea: a work capable of merging with the desert. Polycarbonate thus becomes rock, a transparent crystal, both liquid and solid. Monolite is an element for architecture and design, made of polycarbonate. Each element undergoes a vitrification process that increases its resistance.
