This publication explores the context in which the Mexicali Experimental Project, led by architect Christopher Alexander (1936-2022), was developed in 1975–76. Writer and architect Dorit Fromm discusses the vernacular and communal experiments of the 1970s, and editor Andrea Torreblanca delves into the structure of the Journal that attempts to weave the microhistory of Alexander’s experiment with recent commissions with artists, architects, and scholars. Contributors to the Journal include Georgina Cebey, Dorit Fromm, AJ Kim, Nancy Kwak, Felipe Orensanz, Alejandro Peimbert, Alison B. Hirsch, and the work of artists Pastizal Zamudio and Cynthia Hooper.
