Challenge-driven design for public housing: The case of Hong Kong

Public housing (PH) has existed in Hong Kong for six decades. Previous and current challenges that have been encountered over time function as a collective driver for design progression. However, such challenges have remained under research to be able to draw useful lessons from them. To understand how this established motif can suit the sustainability-conscious era, this study uses Hong Kong as a representative case for sub-tropical compact cities by critiquing its PH design against multiple constraints. The objective of this study is to trace the historical relationships between challenges and design progress as well as to assess current and future implications of sustainability trends on PH design. By synthesizing data from literature, policy documents, and empirical evidence, this research develops an evolution map for PH design in Hong Kong that is driven by seven major challenges. Based on this map, a conceptual framework for intersecting considerations that envisages five main future prospects toward future PH design is also established
