The Kuwait National Assembly Building was designed by Danish architect Jørn Utzon in 1972 and completed in 1982. The structural design was by Max Walt. The overall area of the complex is 18,000 square metres (150 m by 120 m). The main structure consists of a basement housing the services and two upper levels with offices, reception, meeting rooms, the library and the cafeteria. In the centre is the vast assembly chamber. The upper tiers offer 1,000 places for observers and spectators. The public square, similar in structure to the assembly hall, has a huge roof covering the entrance to the complex. Apart from these two halls, all the structures in the complex are in reinforced concrete consisting of 12,800 specially shaped precast elements made up of 150 basic types. All the elements are of white cement concrete with a smooth exposed concrete finish.
