Annual Arca is a pavilion in which architects and designers created a piece reproduced more than 400 times made in Oxford gray granite obtaining different tones thanks to the effect of the lights. At the beginning of 2017, Javier Sánchez, Mauricio Rocha, Héctor Esrawe, Javier Claverie, Rafael Rivera, Jorge Arvizu and Manuel Cervantes traveled to Italy to visit Carrara. Seven architects and designers, of the most recognized in Mexico, with only one idea: to know the origins of marble, its roots and the extraction process. A trip where the relationship between the material and the work was fostered, between producers and architects, a human and non-commercial relationship.
