This paper aims to clarify the representations of the published floor plan drawings by Kazuo Shinohara. They show various expressions between publications, known as it turned to the abstract way in the 1970’s. We first checked his publications throughout his career, and found in which publication he used a different version of plan drawing from former publications. Secondly, representations of plans are classified based on their contents and ways of abstraction, and changes in expressions between different plans are analyzed. We made it clear how the plans had changed in time.
