Mutina and Patricia Urquiola wanted to reprise the traditional artisanal production process typical of terracotta. Elements which come out from earth, imperfect and solid, marked by the hand of man and by time passing. Roof tiles, bricks, hollow bricks and partition walls are undone, unstructured and reinterpreted in a new way, keeping a traditional touch. The wish to exit from two-dimensional spaces typical of standard wall coverings, is translated into the experimentation of three-dimensional bricks, which gives shape to new design elements, whose high aesthetic-functional content enables limitless solutions for indoor and outdoor spaces. Because of its shape, the partition element Celosia evokes the Roman numbering system. The structure followed for its installation creates dynamic and unique partitions.
