"Three years away from the 2l century, Istanbul has gained huge dimensions which is very hard to manage and a quite different image regarding to 20's and 30's. Now, it has several high rise buildings, "modern" looking residential areas and a network of highway with a chaotic traffic. Thus, the city has many business and trade centers, various types of housing regions and social organizations serving to different social classes. People survive in these environments earning money, educating their children and trying to continue their sociocultural existence. In fact, every moment they live, modifying the present spatial structures they attach different properties to the city. Space is built by users either physically or mentally at first but continued to be evaluated by the time according to changing social, economic, ideological and psychological conditions. Ordinary people learn how to construct a space culturally. Most of the time, living in a space and reconstructing it every minute they are unconscious about the process. Some given codes lead people to reshape their environment and develop certain meanings. Istanbul, especially the Historical Peninsula being the core of the city suggest a suitable case to scrutinize environment/man relation. The aim of this paper is to discuss on "how" of this continual structuration of space at this special situation in order to equip the related theories with original information. It is necessary to understand the serial of characteristic meanings that are produced parallel to the "structuring structures". In order to detect the articulations of man to environment the users will be observed and photographed at certain times of days. A morphological study is needed to understand the physical conditions better. After these endeavors, the users will be interviewed and their spatial modifications and cultural accumulations will tried to be captured."
