Research on the Renovation Design of "Streetside" SpacIn Guangzhou’s historic urban districts, streetside spaces serve as vital carriers of residents’ daily activities, encompassing social, commercial, and landscape functions. However, traditional urban planning and design have paid limited attention to these spaces, particularly in high-density residential neighborhoods where issues such as functional mixture, spatial disorder, and insufficient public accessibility are prevalent. This study focuses on the western segment of Wenming Road along Yudai Moat, conducting a comprehensive analysis from three dimensions: historical evolution, current site investigation, and international case comparison. Based on these, adaptive renewal strategies and specific urban design guidelines are proposed.
