Christopher Alexander’s Challenge for Implementation: Report from an ESRG Symposium

Abstract The architect Christopher Alexander was one of the most influential figures of late twentieth-century urban and architectural theory. His books Notes on the Synthesis of Form, A Pattern Language , and The Nature of Order have been influential across a surprising variety of fields. Yet Alexander struggled with implementation over his own career, and in advising others on how to take forward his ideas. One offshoot of this effort has been the Environmental Structure Research Group (ESRG), a research coordination network convened by his student Michael Mehaffy (the author). This paper reports on the proceedings of the group, including its meeting in Krakow, Poland and over Zoom in September of 2022.
