View From Signal Hill, with Robben Island in the back ground
You might have noticed that the stadium bowl is surrounded by a podium/concourse/plaza
This was necessary, since its all rock underneath, and removing the rock would have cost too
much so its to reduce and soften the visual and height impact of the stadium structure
Under the podium entrance level are two floors, they will mainly be housing parking bays and players’ operational areas. The underground areas also have an extremely complex ventilation design to supply and extract air and smoke and pressurise corridors, to keep the crowds safe, in the event of a fire anywhere in the stadium .
