Revision with unchanged content. Ever since the advent of modern theories in architecture and design, the concept of Rationalism has revolutionized the process of design in the built environment. Rationalism, being the art of logic, has elevated this profession from decoration to design. A number of designers and theorists have tried to encapsulate logic, function and aesthetics in the formulation of approach to develop an architectural vocabulary for the built environment. Space and time, being two important aspects, play crucial role in the perception of built environment. This book addresses the concept of space-time dynamics in the built environment and explores its application as an approach to design. The research explores this concept from a multitude of perspectives ranging from scientific to philosophical views. The end result may not be a completely new definition design, but is an expanded view from various perspectives bearing the potential of developing new perception. These approaches can be sensibly used towards the spatial solutions to enliven the present urban realm. This research is directed to the professionals, researchers and students in the field of architecture and design.
