Recently, there has been growing interest in studying spatial morphology via different socially responsive approaches, however few studies have focused on how the hidden dimensions of the built environment do reform the physical characteristics of spatial form. Therefore, examination of spatial organization of some historic city centres appears to show a more integrated relationship between ideological dimensions of city life and the physicality of city fabric. When city planning and design development separates ideological and physical dimensions there is evidence to suggest that this can lead to detrimental impacts on the well-being of inhabitants and the physicality of city fabric. There thus, this paper explores and develops a theoretical model, the anatomical approach, derived mainly from practical and academic experience and literature review. This analytical method, from the paper’s perspective, is considered to be as a sun glasses; if you put it on, then people can read and see the surrounding environment differently that is because it helps to understand the morphological structure of urban spatial morphology via understanding the mechanism of social sustainability as a holistic approach of urban sustainability; in specific settings that have multi –layers of historic developments. Firstly, this approach appears differently, in different cultures according to different styles of public life which is reshaped by various ideological paradigms whether was human rationality, in Western culture or teachings from god, in Middle Eastern culture, (Akbar, 1999). This is as well as social forces, thereby identifying different applications of anatomical approach according to different ideologies and classifications of open spaces in Western Europe, Latin Europe and Middle Eastern Cities. In this regard, the paper analyses how the ideological model, as a collective of religious, political and cultural values or principles that lie beneath the physicality of the city and has become increasingly separated from the city physical form and spatial organization, develops through three main phases into aesthetical planning conventions. In these three phases, the paper has documented the agreement and disputes between people as an important step towards the refinement of these conventions. In this context, the author explains the main aspects of the conventions, as tool maintaining social sustainability and spatial morphology, the valuable aspect, the tactical aspects and the aesthetical aspect. At the end, it concludes how the tactical aspects together with aesthetical aspects of the conventions, play the key role to maintain social sustainability and finally characterize the spatial morphology within this social sustainability. In this respect, this approach contributes the planning education process by providing the essential knowledge and the analytical base which are considered to be as an advanced step for the site analyses, design process of urban spaces and the conservation of urban fabrics in valuable contexts. This has been studied via three cases of urban fabrics, Cairo, Egypt as Middle Eastern space, Rome, Italy as Latin spaces and in UK as Western Europe spaces by using maps, graphical analyses and observational methodologies, photos and historic maps. This exploration, ongoing at the time of writing, contributes to PhD research that will ultimately develop and describe a fuller anatomical approach for the analysis and design of such urban settings.
