Taking as a point of departure specific exemplary houses, both vernacular and high-style architectural forms are studied from the perspectives of the history of style, of technology, and of social use. We look at space (interior space, the relationship of structure to site, the relationship of site to environmental and economic context), and we look at interior design and materials as well as at plan and expressive form. Both the class as a whole and the student research projects take a case-study approach. Considering examples from the 17th and 18th centuries as well as from the 19th and 20th, the class will provide students with a broad background in habitation in what is now the United States as well as experience in hands-on original research concerning the built environment today. While much of our attention will focus on unknown builders, we will also study some of the best-known houses (and most widely-dispersed models). Architects whose work we will consider include Thomas Jefferson, Frank Lloyd Wright, Charles and Henry Greene. three hours of lecture and one hour of discussion per week. One all-day Saturday field trip.
