The project is located in Snail Bay area of Kunming, which was once a wholesale market and prospered at that time. In order to revitalize the land, the government upgraded the original site and replanned the surrounding area around Central Lake Park. The city exhibition hall is designed to show the future development of Luoyshi Bay area.The old building to be renovating has been abandoned for five years,but is adjacent to Central Lake Park and has excellent natural landscape resources. The challenge was to replan the interior and activate the exterior realm without changing the structure.
