This course serves as an introduction to the major concepts and historical circumstances informing architecture and urban design in the 20th century. Central themes include the impact of advances in modern technology on building forms; changing attitudes toward ornament and eclecticism; the rise of the metropolis and the suburb; and the socio-political concerns underlying most of these issues. Although lectures focus on Europe and the United States, we also consider major projects in Japan, India, and South America. Students become familiar with the works and words of noteworthy architects, from Le Corbusier to Frank Gehry, and the revolutionary messages of architectural groups, from the destructive vision of the Italian futurists to the comic book-renderings of a nomadic architecture posed by Archigram. Course material is presented through posted lectures and images, but students are encouraged to visit sites of architectural interest in their community.
