This paper is an attempt to clarify the structure of forms through an analysis of Alvar Aalto’s architecture. The analysis was performed as follows. First, the architecture was decomposed into its elements. Then, these elements were classified into groups, and the relationships between the groups were analyzed. Finally, variations in architecture were analyzed. Through the analyses of three houses, this study found the opposing characteristics of the groups, such as Internationality and Locality, Openness and Closedness, and these oppositions are reconciled by mediators. This “reconciliation of opposition by ambiguous mediator,” is the structure of forms, as concluded in this paper.
