The Shenzhen Huangmugang Transportation Hub is a development project of an underground space, which functions as the interchange for three metro lines, the overground and underground slow traffic, and the commercial leisure and entertainment space.

On the basis of taking down the original flyover, the Project adopted an innovative and integrated design of the "Tunnel-Station-Bridge". In the design, the skylight, atrium and greenery have been introduced on a large scale. The design thoroughly has improved the problems of function fragmentization, lack of slow traffic system and poor landscape in urban areas. It has formed an integrated underground space more naturally and comfortably, improved the convenience of community life and led to the rapid development of the areas.

The underground space of the Hub features a unique structural style of V-shaped giant columns. Lots of skylights are set on the roof. Vehicular tunnels are suspended inside the space. And staggered atriums are deployed on each floor. The space form innovation from the top to the bottom has created a bright valley in the underground space, where a variety of trees are planted.
