Pictures and video: Designs released for possible Heathrow expansion

Heathrow Airport has released new concept art of what a possible expansion could look like in a bid to prove its plans are 'ready-to-go'.

Grimshaw Architects was appointed to produce the images which show what the inside and outside of the airport would look like.

Head of design at Heathrow, Barry Weekes, said: “We look forward to working with Grimshaw to develop their bold ideas so that once the government approves the Heathrow expansion, we can create a world-class sustainable hub airport which delivers for our passengers, our airlines and also helps to integrate Heathrow with our local communities.

"With the Concept Architect and Programme Client Partners now in place, we are now ready to begin the process of expansion once the government makes the right choice for the whole of Britain.”

In July 2015, the Airport's Commission stated an additional runway at Heathrow presented the 'strongest case'.

A spokesman for Heathrow Airport said a decision from government as to whether the expansion will go ahead could be decided by October.
