Ensuring the continuity of historical urban fabric during the process of urban renewal holds significant practical importance. One of the central concerns of urban regeneration in the age of stock-based development is how to reconcile the spatial forms supported by the original fabric with current functional requirements, and how to improve the environmental quality of the block while preserving the unique historic fabric. As the basic unit of urban spatial organization, the configuration of plots determines the spatial structure of the city and is a key factor in shaping urban fabric. Morphological control at the plot level is an effective approach in urban renewal to balance urban fabric and spatial functionality.
