Abstract
A floor plan in architecture includes elements that determine circulations of a person who experiences the space of the architecture and that is considered to play an important role in the connection between the person and the architecture. Especially since modern times, various shapes that deviate and escape from a floor plan by means of right-angled constitution have arisen and have been used as elements of architecture. Therefore, it is necessary to consider "a floor plan". In this paper, we propose an index "Grade of surprise" that is able to classify various floor plans in architecture from the person's view. We analyze floor plans of architecture by famous architects as some samples by means of a proposed "modified box-count method". We compare the results and make consideration.
