Due to the increasing numbers of the passengers and the aging of the existing passenger terminal, a new terminal intended to become the main terminal of Zagreb Airport with a capacity of 5 million passengers per year was planned to be built. 17 architects (7 international, 10 local) were invited for the competition and Shigeru Ban Architects were selected as the second place. The requirement was to design an environmentally friendly terminal. A timber structure was proposed to cover the entire terminal for the amount CO2 emission throughout the construction process is one fourth of that of a steel structure of the same scale.
