Concept designs have been unveiled for an expanded Heathrow.
Visions from four architectural practices were shortlisted to define what the West London airport could look like with a third runway.
Zaha Hadid Architects, Grimshaw, HOK and Benoy will compete for the role of concept designer.
“The visionary concepts are just the start of a dialogue which will fundamentally redefine what an airport is; how it looks and feels; how it interacts with its environment and an increasingly demanding generation of new passengers; and importantly, enhance how it connects with the communities around it,” said Heathrow head of design Barry Weekes.
“Our ambition for expansion is to transform Heathrow once again – building Britain a value-for-money global gateway at the forefront of sustainable development and innovative design.”
The government-commissioned, Sir Howard Davies-led Airports Commission last summer recommended construction of a third runway at Heathrow.
Heathrow chief executive John Holland-Kaye this week wrote to prime minister David Cameron setting out a series of measures to support the proposed expansion project.
