In the pursuit of improving the quality of our built environment, public spaces take the highest priority. Our everyday activities and interactions with other people, take place in these spaces. The focus of the Dynamic Passageways research is on the qualities that create good public corridor, which is essentially a very long and narrow public space. An analysis of three unique towns in China reveals how buildings are designed and arranged to create high-quality, highly populated passageways. By studying the passageway and applying what is traditionally an urban design element into architecture, new synergies can be formed to create more interesting and more connected urban spaces. The vision is that this research will provide input to the ever expanding discussion on improving the design of our public realm, both within a building and outside it.
