Characters should be 12 point or larger.  Double Space.

First, VERY Brief summary of the book. (250~300 words.  Write succinctly.) Then, you are expected to discuss what Le Corbusier was proposing in order to achieve a new type of architecture (Modernism). (400~500 words.)

What was he specifically looking at and what was he learning from them?  Only your original reaction to Corbus thoughts counts.  (Warning: online exegeses of Corbu’s writings, all of which I know about, are mostly superficial and often wrong.)

You have to have brief citations from the reading in order to corroborate your arguments.  Add footnotes, following the Chicago style.
