Planning, Progress and Challenges of Built Environments first examines China's urbanization, presenting a brief historical review of urbanization in China and focusing on its development during the pro-reform period. Following this, the authors explore notions of publicness and privateness through the lens of Hong Kong's public rental sector, using data collected from a physical survey of selected housing estates and 14 in-depth interviews with architects, housing managers and residents. Post-consumer packaging waste is explored and synthesized as a secondary resource for re-contextualizing and developing applications in architecture. The diverse interactions between water and rock masses are discussed, focusing on lines of conceptual continuity from rock masses to built structures made from stone. Issues concerning sustainability at university campuses are discussed in terms of obtaining materials, the impact of the presence of said materials, and the potential of these materials as teaching aids.
