About the appearance design of the cake store, we made two design concepts from the viewpoint of "easy to enter after desiring to enter". We performed one trial about the method to make them. Specifically, we extracted 12 impressions and 48 cognitive parts which constitute cognitive evaluation structure by the evaluation grid method. The questionnaire of five steps of SD measures about 12 impressions was conducted using 25 kinds of sample photographs in October, 2007. From a result, two cognitive evaluation structures were clarified by the interval regression analysis and rough sets. We made two design concepts from this cognitive evaluation structure of this present condition. We asked for design specifications based on each concept by the view of "annexation" related to the creativity which Prof. Norihiko Mori advocated. Creating each 3-dimensional sketch from the obtained design specifications, we verified the concept. As a result, it became clear that the sketch is reflecting the design concept. That is, the design concept deciding method of the proposal was verified.
