Hamad International Airport is designed to have an initial annual capacity of 29 million passengers, three times the old airport volume. Upon completion, it will be able to handle 50 million passengers per year. It is also expected to handle 320,000 aircraft movements and 2 million tonnes of cargo annually. The check-in and retail areas are expected to be 12 times larger than those at the old airport. The airport has an oasis theme. Many of the buildings have a water motif, with wave-styled roofs and desert plants growing in recycled water. The airport is built over 22 square kilometers, half of which is on reclaimed land.
