Abstract
Louis I. Kahn's spacial composition is characterized by traditional motives and Ecole des Beaux which had influenced him. This influence had showed five forms about Kahn's spacial composition. His constituent factors in geometrical form are classified into the propositional system, the cellular multiplication of a special unit, the Poche Space and others. According to the results of this study obtained from above mentioned subjects, it can be concluded that geometrical factors, which constitute space of plan, are totally expressed as a system of order which unites particular ones into whole one. This characteristic had developed into a completed meaning for passing through the residential architecture in 1950's, and showed in the other artworks there after.
