The image of many cities in today's world has been influenced by the growing globalization along with rapidly developing demographic, technological, and economic movements. From the perspective of the last two decades, the increased high-rise development in the world is clearly visible. In recent years, modern high-rise buildings have impacted the city landscape and have become a major issue in terms of the landscape protection of a city like Istanbul with a historical peninsula silhouette. In this study, which discusses the aesthetics of the man-made environment, various factors have been evaluated by the users based on the formal aesthetic dimension in the 4th Levent area, where high-rise buildings are dense. In this context, this study aims to determine the factors that increase preferences in urban landscapes, user preferences, and the attitudes of different social groups towards the place. The main method of the study, which is based on visual landscape assessment techniques, is the visual survey technique which is administered with visuals and which is used for determining the user's perception of the place. 95 individuals participating in the survey were asked to evaluate formal aesthetic parameters for 15 selected high-rise buildings. One-way ANOVA, correlation and regression tests were employed to analyze the data collected through the survey. The findings and conclusions are thought to provide significant resources to city stakeholders in future urban landscape studies.
