The Guangdong region has numerous arcade architecture. From different perspectives, I explore the architectural features of Guangdong’s arcade architecture and present the current status and causes of their preservation and sustainable use. By selecting successful examples of sustainably designed arcade streets or standalone arcade architecture in Hong Kong, Macau, and Guangzhou, I conduct a comparative analysis of their similarities and differences. This analysis identifies the strengths and weaknesses of the current preservation and sustainable use of Guangdong’s arcade architecture. Based on these differences, I propose several strategies to provide a development direction for the preservation and sustainable design of arcade architecture in other regions in the future.
