74 m2 documents a construction project by the internationally renowned architecture firm Elemental in Valparaíso over the course of seven years. 150 families – who had until then lived in part without running water and electricity – had the opportunity to collectively build a cluster of owner-occupied apartments. The film shows the difficult participatory process which didn’t end with the completion of the housing units. Instead, the interior work was left in the hands of each owner – whether they had the means or not.

Pia Mastrantonio studied Architecture at the Catholic University of Valparaíso. In 2012, she moved to Europe in order to focus on public spaces. Since 2014 she lives and works as landscape architect in Berlin.
