A small country in the Middle East is set to significantly increase the capacity of its airport with a state-of-the-art terminal building. The project is set to cost a whopping $4.3bn, which equates to just over £3bn, and will comprise three symmetrical 1.2km wings of departure gates.

Kuwait International Airport will become the new regional air hub in the Gulf with over 25 billion people expected to pass through each year. The new Terminal 2 will span 0.75sq/km and feature an ultra-modern baggage system which will be able to process nearly 3,000 bags per hour.

The terminal building is designed to adapt to extreme changes in temperature. In Kuwait, which has a population of under five million people, temperatures can range between 45C in the summer and 6C in the winter. It can also see heavy rainfall with up to 352mm falling over some years.

The world-class development will also include cutting-edge technology and a streamlined immigration system. It will be designed with a combination of traditional Kuwaiti architecture and modern luxury.

The three departure wings submerge into an open central space that is 25m in height. As well as being a great place to relax, it will be full of amenities for travellers to enjoy.

An advanced air conditioning system will be installed in the terminal to create a consistently cool and pleasant environment. The systems were designed to work in harmony with the terminal's energy-saving targets.

On the ceiling, there will be 8,000 strategically placed skylights to illuminate the terminal. Meanwhile, there will be 81,000 photovoltaic panels on the roof to generate electricity.

The advanced baggage handling system will span a huge 6km. It will be able to securely process 2,930 bags per hour to ensure travellers are not left waiting for their luggage.

Terminal 2 will also boast a total of 120 check-in desks designed to keep queues to a minimum. Passengers will then be able to navigate towards boarding through a range of fixed link bridges.

A metro line from the terminal is also being planned. It's hoped the line will integrate into Kuwait's Transportation Network, ensuring travellers can easily go to and from the airport.
