This study aims to verify the relation between the oppressive feeling caused by single building and group of buildings and physical factors by regression analysis. For this purpose, questionnaire surveys were performed in field experiments. The results of the study are as follows. At first, the aspect ratio calculated from the proportion of a building facade has an effect on the oppressive feeling. It is considered to be the important physical factor in evaluation of the oppressive feeling by single building. Secondly, in case of single building, the configuration factor is a representative physical factor in an evaluation of the oppressive feeling. Besides, in case of group of buildings, the direction of eyesight faced to the buildings also has influence on the oppressive feeling. Therefore, it was ascertained to be difficult to explain the oppressive feeling only with configuration factor in urban space.
