Current street space has complexity such as various building configurations, various street furnitures, and so on. In this study, the objective is to obtain an index that is used for planning streetscape based on a Psychology evaluation experiment and Indication experiment using building volume model. As the experiment method, Total 39models applied to standard deviation of ［Fluctuation］= 0 to 12 of various elements as random number was used, and volume model was made. Psychology evaluation experiment and Indication experiment that whole view of model and individual building of model were indicated when "unity" was felt. As the results 1) "unity of whole" is indicated at ［Fluctuation］ of 0 to 4. 2) At ［Fluctuation］ of 5 to 7, volume models that "unity of whole" is almost indicated and "unity of individual" is also indicated are obtained. From results, useful basic knowledge can be obtained to conduct plan and volume composition for future streetscape.
