The architectural plan is an index of architectural values. It expresses the underlying ethics and ideologies of the architecture; evinces the background environment of building technologies, rules, regulations, conventions, and customs; and traces the power relations that buildings enact. This course sketches the history of plan-making during the nineteenth and twentieth centuries, from Beaux Arts composition to modern “non -composition,” before focusing on the scattershot discourse about the plan today. Rather than positing a single grand thesis about the contemporary plan, the course foregrounds the countless threads of plan making evident today and asks students to identify the underlying ideas, histories, and implications of specific plans.
