Lisbon–based communication & graphic design Studio AH—HA have been quietly and elegantly making waves since its establishment by Portuguese designers Carolina Cantante and Catarina Carreiras in 2011.

Godfathered by French designer Sam Baron, and Benetton's research centre Fabrica, the duo have been adding their beautifully unique, characterful and simple vision to a very diverse range of projects in a holistic fashion.

Featured is the wonderful, monochrome and minimalistic identity design for Portuguese architect Martinho Pita, where Catarina and Carolina used the materials and textures that appear in his work to define the project's clean, strong graphic language.
