The structural organization of the city is defined by two main elements in the body of the city, open and built up spaces. The most important of these factors are the regulations concerning the macro level control of the urban design programs, which affect the city’s overall spatial organization, as well as the quantity and quality of its construction activities, the emerging proportion of the built area to available space, and the quality of its visual corridors and city vistas. Interestingly, the condition of construction and its relation to open space, as well as the proportion of open and built spaces, differ in various districts of the city. The spatial structure of the city, which goes beyond its structural organization, deals not only with the order of open and built up spaces, but also illustrates the connection between the two. The open and public spaces of the city may be divided as follows: - Green spaces (including urban parks, urban forest, farmlands, gardens and orchards); - Roads and accesses (including highways, major and minor streets and road lanes); -Reserve lands of urban services (including old factories, warehouses and uncultivated lands) The central part of Tehran and the southern half of the city are densely populated due to the small size of the residential units. The density in this region is almost twice as much as the average density of Tehran. District 22 has the most and districts 7, 8 and 17 have the least areas of open and public spaces. In districts 14, 7, 8 and 17, the area devoted to buildings is far greater than the area devoted to public and open spaces.
