The Codex series is a set of booklets dedicated to architectural pedagogy. They have been created within the ALICE-Epfl Lab and are edited by Sébastien Grosset, philosopher, Elena Chiavi, architect, Dieter Dietz, architect and head of the lab and Daniel Zamarbide, architect and co-director of the lab. The series presents a non-defined number of terms, one term per booklet and concepts that are useful to immerse into the field of architecture, its scope and potential, the goal being to open possibilities of understanding what architecture can contribute to.
