Problem statement: Squares and streets of a city are the main parts of the public spaces that are considered the showroom of the visual environment of a city. In the past, buildings in addition to being beautiful, they had been accommodated with their background, and with respect to the surrounding environment. Today, the view of many Iranian cities is chaotic and disturbed and this is a result of the heterogeneous and disoriented association of form, activity and space on a large scale, and on small scale, it is due to the lack of harmony and proportionality in the composition of elements of the buildings that are formed together. Research objectives: The purpose of this study was to extract the effective factors on the promotion of formal aesthetics of urban facades and their application in redesigning of Enqelab street facade in Sanandaj-between Namaki junction and Enqelab square-that is located in the historical context and the Primary core of Sanandaj. Since this research seeks to apply the available basic knowledge, belongs to the field of applied research, and as this research attempts to apply some criteria for the measurement and analysis of the environmental quality, it is considered as descriptive-analytic research. Research method: This research tries to acquire a deep understanding of the current state of the area in order to redesign and reinforce the form of urban facades. To achieve this goal, the research process has been carried out in 3 stages: First, we examine theories related to urban aesthetics, then identify the components of the urban landscape and explain the physical goal, and in the 3rd stage a parametric model for the measurement and analysis of visual quality in the urban landscape is presented. Conclusion: The results of this research will be presented as a guideline for enhancing visual aesthetics of urban landscape design.
