After finishing his studies of architecture at the Pontifical Catholic University of Valparaíso, Jullian left his country for Europe, with the declared desire to work with the Swiss architect Le Corbusier.
As chef de bureau at the atelier, Jullian collaborated in such landmark projects as Harvard University's Carpenter Center, the Knowledge Museum at Chandigargh, the Olivetti Laboratories, the Baghdad Stadium, the French embassy in Brasília, and the Venice Hospital.
In some of these works, like the Olivetti Laboratories, the Carpenter Center and the Venice Hospital, Jullian's participation was more relevant than that of a simple collaborator, and he has been identified as a co-author.
[1] When Le Corbusier died in August 1965, Jullian de la Fuente was in charge of the Venice's atelier, working on the second version of the Hospital project.
The Atelier Jullian and Pendleton designed a number of important projects including astronomer Carl Sagan's home in Ithaca, New York.
