We won the competition for the new mixed-use Civic Center in Hengqin next to Macao, which is going to be built in this year. The site is limited between crowded housing area and an open green park. Instead of putting nine programs into a solid building, we adopt a strategy to create an “void” for the high-density urban context, while integrating varies of programs into one complex and interweaving energetic lives together.The main public space on the lower level is composed by three giant arch caves coated by wood and bamboo panels, to create a transparent and open living room for urban life.
