In this study the seven preliminary projects for "Werkbund-Theater" for the exhibition of Deutscher Werkbund in Cologne 1914 are analyzed, and the process from application of the graphic design of art nouveau to the architectural plan, to the birth of the design-method of cubic formation with geometric volumes was made clear. Formal analysis with three items, namely the curvilinear composition with segments, the composition with straight lines and the profile, was useful to clarify the transition process of plan. Then the Theater, which was designed on the basis of van de Velde's individualistic thought of artist, can be evaluated as showing the character of early modernism including irnmaturely both the expressionism and functionalism.
