Thirty years rapid development on infrustructures of the city has left Nanjing, the capitial of Jiangsu Province of China, many underdeveloped irregular patches of lands that need to be reintegrated into the surrounding neighborhood. The Hiden Garden at Fengtai Avenue is one of the public gardens designed to meet this goal. The original comminity has been disconnected by the new built freeway on the west of the site. The idea of "Hidden" is not only to protect the garden space from the negative impacts of the freeway, but also to attempt to visually hide the freeway from the side of residential neighbourhood.
