Built on a man-made island in the South China Sea, the complex has an overall length of 1270 m and a width of 350 m. A clear, logical organization was fundamental to the concept. The large areas of glazing not only afford spectacular views of the sea and mountains; they also result in a better sense of orientation within the building. The roof structure consists of a number of arched elements lined up parallel to each other to create a wave-like form. Since the building is required to incorporate a wide range of functions, the roof lends it a pleasing unity.
