Heathrow has appointed architectural firm Grimshaw to produce concept designs for its £16 billion expansion project at the airport.
The practice was selected from a shortlist of four of the UK's top architects including Zaha Hadid, HOK and Benoy.
The announcement follows on from the appointment of Arup, CH2M, MACE and Turner & Townsend as Programme Client Partners in March.
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."
Partner at Grimshaw, Jolyon Brewis, added: "We are passionate about designing a new future for Heathrow Airport; setting a benchmark for sustainable infrastructure, skilfully integrated with the communities it serves. Heathrow have ambitious plans for the expansion of the airport and we are proud to be selected to help deliver this inspirational vision."
