Fundamental argument of this paper lies on the differentiation between the two aspects of architectural space : that as geometrically represented entity and that as cognitive entity in our mind. An experimental analysis here showed that several different floor plans can be drawn from single cognitive description of real architectural space written in an essay. Further analysis on 70 plans drawn by the subjects in the experiment showed that there underlies a certain sort of structured "orientation system" for each drawing, which is constructed from the perceived "directions" of verious parts. Based on this result, the authors tried to reinterpret a series of previous contributions to cognitive map studies and to highlight a cognitive aspect of architectural drawings.
