High-rise buildings facades due to their scales are among the most prominent elements of the urban landscape; hence, they can be utilized to improve the urban landscape. Despite the efficiency of high-rise buildings, they have the potential to cause problems such the urban landscape disruption as well as eliminating the order of urban space. Since today, tall buildings are considered as effective phenomena in modern cities, the enhancement of their aesthetic quality can improve the aesthetic quality of urban landscape. Hence, the main purpose of this paper is to investigate the aesthetic relationship between formal characteristics of high-rise buildings and people’s and experts’ preferences. One of the factors associated with the beauty of high-rise buildings is their complexity which has rarely taken into consideration in scientific studies. Therefore, it is attempted in the present paper to find the relationship between complexity of towers facades and their aesthetic quality. The main variables of the research include the level of complexity, the openings model, and the color of tower. Statistical analyses by SPSS were used to assess the people’s and professionals’ opinions concerned with determining the impact of complexity on aesthetics of high-rise buildings. The results show that both people and experts prefer vertical openings for towers. Also among the experts, less complexity is more favorable while from the ordinary people’s viewpoint, the opposite is true.
