In the aspect of urban renewal, the monotonous "super block" mode of industrial area in contemporary China causes low efficiency of space utilization and indifferent communities. Therefore, it is essential to share the big blocks with multiple land-use and various patterns of development. This paper takes the Hanyang Iron Factory in Wuhan, China, as an example, to explore the optimal scale of sharing blocks in regeneration of industrial heritage. The paper surveys on the operation conditions of retail stores in four regeneration projects in Wuhan and categorizes the shops by amount, location, area, shape of floor plan and measures their economic and social performance. Results of the performed study show that "Sharing Mosaic" blocks, which combine the scattered space of the whole site through pleasant small-scale streets and buildings, greatly increase the accessibility and efficiency of the original site. Accordingly, the paper proposes a new regeneration strategy: Firstly, to provide more possibilities of sharing, the original 150 meters super block is divided into small 60 to 75 meters plots; secondly, design six different modes of function-sharing plots, combining commercial, residential, cultural and other functions; thirdly, various scale of modular units for different types of sharing space are inserted into the central of each plot, generating plenty of dynamic cores. By dividing the super block into diverse small-scale function-sharing plots which allow for diverse cultural landscape, the "Sharing Mosaic" pattern blurs the boundary of functional zones and create more space for people to share, revitalizing the old industrial area. With the help of these appropriate scale and patterns of development, an organic social structure network has been rewoven for the depressed site, providing reference for similar cases.
