Roth breaks down the concepts of commodity, firmness and delight. He does so using examples of architectural works by Walter Gropius, Ludwig Mies van der Rohe, Eero Saarinen, Louis I. Kahn, Frank Lloyd Wright, Le Corbusier, Alvar Aalto, and Cass Gilbert, among others. Please choose an example from the text of a work by one of these architects and describe how it relates to either commodity, firmness or delight. In addition to re-presenting Roth's statements, be sure to explain why you agree or disagree with him and come up with original comments/thoughts about the structure you have chosen to discuss.
