Foster + Partners has seen off competition from Zaha Hadid, Rogers Stirk Harbour + Partners and Pascall+Watson to bag the £1.8billion airport expansion project
The 550,000m2 terminal will be enclosed within a continuous lightweight gridshell, embracing walls and roof in a single, flowing form.
The building will have a roof spanning more than 100m - three times the span of a conventional airport.
The new complex is expected to handle 40 million people a year through more than 70 gates.
The state-funded project is expected to be operational by 2018, with construction set to start next year.
