Abstract
This paper, noting skylines comprised of roof shapes, proposes desirable cityscapes for two types of groups one of which consists of subjects who attach importance to uniformity and the other of which consists of subjects who does not. A comparison is made between a stimulus (Case 2) in which roof shapes vary over town blocks and a stimulus (Case 3) in which roof shapes vary over and within town blocks. The inferred evaluation score of each time period implies that synergistic effect of sceneries in town blocks arises in both stimuli. Furthermore, the average of evaluation scores across subjects who attach importance to uniformity show the superiority of the stimulus of Case 2.
