Design strategy for urban multi-story residential regeneration from the perspective of built environment levels:two cases in Nanjing Xiaoxihu Traditional Block
Multi-story collective housing located in historical urban areas,mostly built in the last century,are facing many prob-lems.Based on the concept of"levels"in Open Building Theory and the interpretation of the built environment levels from spatial and temporal dimensions,this paper has analyzed the complex regeneration prob-lems in two cases of collective housing in Nanjing Xiaoxihu Traditional Block with the four progressively advancing themes as"place,structure,shell and programme".The aim is to systematically construct the design strategies and methods for the collective housing regeneration in urban residential historical blocks.
