RANDOM network was founded in 2004 after Rafael Saraiva and Thais Meireles, working at PAA/Jauregui, won the competition organized by IAB (Institute of Brazilian Architects) that year. The project, called "The City as a Sustainable Process", was coordinated by Rafael.

In 2005 RANDOM won the closed competition to renovate the Astoria Gallery, in Ipanema, but the project was not built.

In 2006 RANDOM partnered with Andres Passaro, Diego Portas and Marcos Favero for the Stefan Zweig Centre competition, for which we won 2nd prize.

In 2008 RANDOM partnered with firm Artetec to work on the masterplan for the Maracana Multi-modal Hub. This project won an Acknoledge Prize from the Holcim Awards of Switzerland, in a cerimony in Mexico City.
