In the underdeveloped society of the late Qajar era, the source of inspiration for urban development was the celebration of the Ancient Persian culture and civilization, making nationalism to become the basis for development actions at the national level in the First Pahlavi era. Social, economic, and technical changes in Iran, along with the Iranian statesmen, intellectuals, and graduates' visits to Europe, have led to the formation of a movement in Iran's urban planning that more than anything, has influenced alleys and passages; thus the construction of "street", as the axis of urban development, with a linear model, was at the forefront of urbanization activities. The continuation of this urban policy for two decades has led to significantly greater changes, especially in the appearance of streets, making the aesthetics of the streets a core issue. The effects of these changes have greatly influenced the users' perceptions of the street in the First Pahlavi era, the impact of which is still present. Lalehzar Street was considered one of the main streets in the center of Tehran in the late Qajar and the First Pahlavi era. The present study aims to find the governing relationships in the development of aesthetic policies for the construction of streets in the First Pahlavi era. To this end, it investigates Lalehzar Street in Tehran in terms of the aesthetic criteria considered for the streets in the First Pahlavi era period by reviewing urban regulations related to street construction, approved in the First Pahlavi era. The present study is historical-analytic research, and urban regulations related to street construction, approved in the First Pahlavi era, are considered the most important source of analysis. First, the aesthetic criteria for street construction are explained. Next, Lalehzar Street, as an example of the streets constructed in the era studied, is analyzed in terms of these criteria.
