The purpose of this paper is to study how the idea of “mobile equilibrium” is expressed in building design of Louis Sullivan, following our former papers. In this paper, we analyzed the relationship between the idea and the contrasting composition on the facade of his buildings. In many of his facades, “the mass” which is static, rigid and massive and “the detail” which is dynamic, organic and delicate are clearly contrasted. By this contrasting composition, Sullivan expressed in his facade the idea of “mobile equilibrium”, both “emotional and intellectual”, both “subjective and objective”.
