MAIO is an architectural office based in Barcelona that works on spatial systems that allow variation and change through time. MAIO's projects embrace the changing complexity of everyday-life while providing a resilient, compromised and clear architectural response.

MAIO's members combine professional activities with academic, research and editorial ones. They have been in charge of the magazine Quaderns d'Arquitectura i Urbanisme (2011-16), and currently teach at ETH Zurich, the ETSAB/ETSAV (Barcelona), and Elisava - Escola de Disseny i Enginyeria.

MAIO is run by Maria Charneco, Alfredo Lérida, Guillermo López and Anna Puigjaner, who recently has been nominated finalist of the Rolex Mentor & Protégé Initiative 2016 and awarded with the Harvard GSD Wheelwright Prize.
