After completing his professional training with architects Enric Miralles in Barcelona and Stéphane Beel in Ghent, Gustavo Silva- Nicoletti (ETSAV-UPC, 2000) founded the Onze04 agency in Barcelona in 2006. Since 2011, the agency has also been based in Nantes, where Mathias Gerhardt joined him in 2013.
With a strong track record in Spain and France, the Onze04 agency works on projects of various types and scales, covering all typologies: housing, public facilities, offices, and interior design. It designs and builds new constructions as well as rehabilitation and renovation projects, regardless of their size or complexity.
