The external facade of the stadium is made of bronze and copper cladding systems, and glazed curtain-walling. A copper mesh veil wraps around the facade, as well as the external stairs, offering privacy and protection from the sun. A number of solid bronze-clad volumes protrude from the veil and curtain-walled exterior, providing views of the surroundings from the dining rooms, bars and internal atrium space.
The southern elevation features a curved cantilever structure, above the entrance and ticket office, made from more than 4,000 individual interlocking bronze panels. The bronze cladding continues below to the entrance to create a reflective soffit and flows into the interior.
Different climatic conditions will change the tones of the bronze and copper facades to a dark reddish brown colour over time.
