In this context, “Observation Method” was used for users orientation in the fields (sqaures).By this method, we can do users observation and users mapping analysis. By This way to compare the data obtained with the mathematical data used Space Syntax method.Space Syntax is an user-oriented method. In this way, we can obtain data about using space and user orientation in the space. So, square’s circulation and static fields are determined. Also, by this way, planning data is prepared for space design and arrangements (renovations). By using the methods, functional and useful spaces will be provided at the same time the production of sustainable spaces. In this research, Sultanahmet Square in the İstanbul Historic Peninsula is selected for application area. The method has been tested in this area.
