Starting from respecting history, sincerely and rigorously think about how to renovate this "old building". After a micro-treatment of the symbiosis of the old and the new, it becomes a touchable time interface. During the renovation process, in order to preserve the memories of this generation, we carried out a large number of targeted structural renovation designs. Different from simply putting a new spatial scale inside a retro and nostalgic old shell, we believe that urban renewal should not be a rough covering of time and space. The new part is the lifestyle.
