The firm of Architettura 4e was founded in 1996 from the collaboration of the architects Fabio Costanzo and Maria Rosaria Piazza. It deals with public and private architectural design, renovation and interior design, mounting exhibitions and industrial design projects. Together they have participated in shows and architectural competitions. The firm’s design research envisions architecture as an art that generates emotion, where the knowledge of technique cannot be disassociated from poetry. Their work favours care with details and a study of design that is attentive to particulars and construction traditions, with research directed to the masterly use of materials and technological innovation in the field of environmental sustainability.
