Heathrow Airport has chosen Grimshaw to draw up concepts for a ’hub airport of the future’ as part of its ambitious £16 billion growth plans.

The airport, which plans to build a controversial third runway, said Grimshaw’s appointment sent ’a clear signal to the government that Heathrow is a ready-to-go, privately financed infrastructure project’. ... However, new prime minister Theresa May – whose Maidenhead constituency is close to the airport – has previously opposed expanding the airport, raising concerns about noise, reaching climate targets and night flights. Two of her key allies, education secretary Justine Greening and chancellor Philip Hammond, also oppose a third runway at the west London airport.
