Presence of a direct reciprocal reationship between form and space (Joe-dicks 1985) makes it necessary to undertake an attempt to develop an un-derstanding of space urban space as such in order to identify the points ofdeparture of the investigation of formationof urban environmet. Since thegeneral term 'space' coprises a number of dirverse phenomena, and the dif-ferences between the various concepts are in themselves a source of misun-derstanding, the matter of what meaning space possesses in built environ-ment seems to be the basic issue in this context.The main point here should not be a notion of space in all different manifes-tations to be found in philosophy since Greek Antiquity; nor a mathematicalunderstanding of space, nor the abstract idea of space one encounters inmodern physics. We should be concerned with space In urban environmentwhich has been considered as 'the medium of urbanism' by Peterson (1989:76)Amongst the various types of spaces, 'existential' space/urban space hasbeen considered the most important one, as relevant to a phenomenologicalunderstanding of place. Existential space in urban level Is analysed and rep-resented by a number, of schools with different analytical techniques.Amongst these, Cullen's (1971) and Lynch's (1960) techniques have beenthe most influencing ones. Cullen's analysis, which is based on serial visionof spaces from the perspective of the person in the street, is too visual,whereas Lynch's is biased by being aggregated and mapped into the cognitivespace of formal street plans. However, these two approaches collectivelypresent some of the more significant elements of urban space and suggestsome of its structural components.Studies also showed that existential space is not a logico-mathematical termdealing with geometrical grids merely, but comprises the basic relation-ships between the man and his environment (Norberg-Schulz 1971; Ch.2). The important aspect here is that within the urban level, the individualpossesses his/her more 'private' existential space, but it is essential thatthis is understood as part of a larger whole. Such an understanding growstogether with man's gradual becoming part of a social context. 'Socialzation',thus, has to be accompanied bythe development of existential space to becomereally meanigful. What meaning the term 'urban space' holds within the ur-ban structure needs to be clarified to examine whether the concept of urbanspace retains some validity in contemporary town planning and on what ba-sis.The research into the existing theories/methods of urban spatial design re-flect the need for qualities of spatial definiton, connection and values of his-tory and culture. Therefore, we need an integrated approach to urban spatialdesign which responds to these qualities and incroporates change and inno-vation to give added maning for contemporary users.
