Bjarke Ingels Group (BIG) and Heatherwick Studio will design Google’s headquarters in King’s Cross, London.
The 10-storey building will have a floor area of 650,000 square feet and will be part of the technology firm’s London campus, which will house 7,000 staff and cost £1bn ($1.2bn).
It will accommodate a rooftop pool and indoor football pitch and will be "as long as the Shard is tall".
The duo have taken over from AHMM architects, the firm that was originally due to design this part of the project.
BIG and Heatherwick said: "From the beginning, the project to give Google a new home in King’s Cross has been extraordinary.
"Rather than impose a universal style on Google’s buildings in the UK and the USA, we have tried to create an interestingness that fits the scale and the community of King’s Cross – the Silicon Valley start-up garage meets the London train sheds in a building that couples clarity with eccentricity and anchors innovation with heritage."
BIG and Heatherwick’s design will join two other projects by AHMM and Mossessian Architecture.
Google’s buildings are part of a larger 27ha redevelopment project in King’s Cross containing over 50 buildings and almost 2,000 homes.
There are not yet any renderings of BIG and Heatherwick’s design.
