A nucleus of light between the exhibition buildings acts as an entrance and fulcrum, connecting the 6 levels and the functions of the entire complex. Everything overlooks or crosses the large underground square, like ‘wadi’, a depression carved out by nature. It is a square, a pool of water on which the silhouettes of the buildings are reflected, developing special or daily actions, a little theater, a little garden. The office block has a neutral color, a gray that accompanies its operational functions and emphasizes the margin towards the north. The large green space, in which the complex is immersed, is soft and undulating, furrowed by tree-lined avenues and paths like an embrace to buildings.
