Space Flow: Past, Present and Future M Alaa Mandour Assoc. Prof. of Architecture Helwan University Abstract. Space Flow between periods of time is always a deep dimensional projection of human beliefs. At best it can provide an echo of a spiritual universe which integrates man in a meaningful order and provides him with essential inner fulfilment, by the very fact that his small personal world is in harmony with a much larger reality. The conflict between the traditional culture and modern systems of thought has to be seen in this wider philosophical context, for the controversial issue is the interpretation of "development" and what it should entail: should development enable the balanced realization of the totality of human faculties and capabilities, or should it reduce reality to limited aspects of material life at the expense of other qualities? Should it promote an increase in quantifiable production only, or should it support a different type of creativity, which includes more fundamental forces and experiences? As far-fetched as these questions may seem, they determine the cultural responses which eventually generate the built environment and its physical expressions. This paper is an attempt to answer the following questions: What are the contributions to discover the potential of continuity between Past, Present and Future? By analyzing and interpreting basic urban and architectural patterns and by exemplifying, how some of them can be adopted or re- interpreted in a contemporary context?, how to deal with the problems and incompatibilities caused by the impact of time differences, both in philosophical and in practical terms? And what are the new alternative approaches which could reconcile traditional principles, contemporary needs and the living future? Keywords: Deconstruction of history, Restructure of time, Heritage, continuity, Urban Merge.
