MAS studio is a collaborative architecture and urban design firm directed by Iker Gil.

MAS studio takes a multidisciplinary approach to its work, with teams including architects, urban designers, researchers, graphic designers, and photographers among others, in order to provide innovative and comprehensive ideas and solutions.
