China South City (CSC):
Zhengzhou Plot 4 HOSPA Proposal

Location:
Zhengzhou, Henan, China

Description:
The project is a 196,000 m² HOSPA mixuse proposal. The project features four towers and a podium mall. The four towers consist of one office tower, one business hotel, two apartment towers, one four star hotel. The podium mall program contains a movie theater and a convention hall. In order to create a minimal zone for vehicular circulation, the hotel and office towers are located on the east and west ends of the site. In return, the north and south edge can be dedicated for pedestrian use. The business hotel tower and the apartment tower are aligned to the southern side to increase the flexibility in designing the mall's internal space and minimize the impact of tower cores on mall retail spaces.

The mall shopping experience revolves around the main central atrium space. The central atrium space focuses around a central stage, which appears as a recess in a golden egg. The central atrium is cladded with a glass facade that encloses the movie theater program, located on the third and fourth floor, the food court, located on the third floor, and a large department store, located on the ground and second floor. The transparency of the glass skin enables people to be able to see performance while traversing behind the atrium stage.

The circulation is a 200 meter long close loop system with single loaded storefront. The design spaces the escalators 30 meters apart and uses a crisscross circulation to promote a better distribution of shoppers to various retail areas of the mall. The central vertical circulation revolves around the central stage and stepped back to give an opera like spatial experience.

Due to the north and south elevations being close to 120 meters long, the need for a non-continuous facade is a necessity. The design implements elevation breaks as the main mall entrances. The breaks are what give grandeur to the mall entrances, while solving the problem of a continuous monotonous facade. The client's requirement of a four star Hotel and Office tower to be seen as a tower starts from the ground rather than being a building starting after the podium level, which is achieved by intersecting and pulling the podium facade away from the tower and gives the illusion of an independent tower form. The podium uses a repeating curve module mullion system that is shifted up and down to create an illusion of a moving wave. On the top of every exterior store front has integrated advertisement spaces to enhances the commercial atmosphere.
