ZAP began the Sky City project in early 2018, which is also a typical Vanke subway superstructure project. The project is located on the third floor of the subway and the site space is very compact and limit. After fully communicating with client, ZAP uses the design intent of the mountain and stone to create a relatively quiet courtyard experience. And because of the length of the ramp of nearly 100 meters on site, the design hopes to reach the venue by creating a more ceremonial entrance corridor. And from a more noisy environment to a relatively quiet homecoming experience. The design also creates stone and pumice, and blends the indoor courtyard with the landscaped courtyard.
