This programme explores Peter Eisenman’s architectural and theoretical works, as well exploring his opinions on the state of architecture today. Eisenman’s new book, Ten Canonical Buildings: 1950-2000, is explained in the context of his built structures, while his theory of coding and its application in his ongoing project for the City of Culture of Galicia is outlined. He presents his views on the relationship between architecture and the public, using this to address the issues of sustainability and consultation. Eisenman also discusses his ideas of “undecidability” and “erroneous interpretations” in architecture.
