M—AO Martins Architecture Office challenged Design by OOF to renew their identity and all graphic material for their daily work. In order to have total autonomy to use the materials developed, the identity is based on a system of coherent grids and scales across all media. In line with the work developed by M—AO, the black on white and the use of a grotesque font result in a clean and contemporary identity adapted to the needs of the studio.
