Woof and warp: a spatial analysis of Frank Lloyd Wright's Usonian houses

The design of low-cost system-built housing has been one of the central preoccupations of modern architecture. The Usonian house was Frank Lloyd Wright's answer to the problem. It was conceived within a planning grid which also determined the constructional system, and refined and developed the design discipline of the earlier Prairie houses. Wright sought to integrate this planning geometry with the demands of the site, and it is for this that he is best known.
