The two subjects theory and traditions have been separately taken in general studies which refer to both general and detailed aspects of them, also explain the effect of each on community and multiple cognitive fields including architecture. However, most of these studies did not address clearly the relationship between them or their effect on each other. So this research studies all of the above in details based on the in-depth study of the intellectual aspects of both concepts, and attempts to find the bases of correlation and difference between them and to put forward the recapitulation out of them. This has been shown during the course of this research down to clarify its reflection on one of the architecture models that is the "Islamic Architecture" as an important and clear model which clarifies the correlation between theory and traditions, and its reflection on the production by displaying the urbanism privacy features for Arab-Islamic City and clarify the details of those features. Hence the research problem can be defined as "Lack of clarity of cognitive perception about the impact of theoretical foundations in contemporary architecture on the formation of general features of traditional architecture in general, and particularly on the traditional architecture which is affected by the Islamic architectural features as a model", so the aim the research is to clarify that cognitive perception. While the research hypothesis can be defined as "the effect of the general basis for the theory of contemporary architecture on specific indicators within the general features of traditional architecture, which adopted the characteristics of Islamic architecture as a model, and resulting a developed architectural feature which are in between".
