The intention of this paper is to make a thematic explication of both the Modification processes and the internal systems of the form of Modern Houses. The analysis will be in three chapters as follows: Chapter 2 illustrates the fundamental meaning of the plan and the modification process through the words of Le Corbusier and Kahn. Chapter 3 presents three diagrams derived from analysis of the form of seventeen houses by Kahn. Chapter 4 presents two intentions of form analysis : The conflicts between form and internal needs. The synergistic relationship between house and garden. The true meani ng of "the work of house" is in this interstitial place.
