The conference "Proyecto+Investigación 2. La lógica del proyecto: 6 elementos + 1 acción" that appears in this publication took place in October and November 2011 at the A Coruña School of Architecture. This conference suggests as the main topic the reflection on the logical processes of creation; their precise systematization in order they become transmissible. Ricard Pié was asked to analyze, diagnose and propose an intervention from the concept "Limit", which is the title of the lecture and article.
