Google will relocate its UK headquarters to a site near King's Cross in London.
The search giant has completed a £1bn deal to buy a 2.4 acre site near the station, where it will build a seven and 11 storey complex of buildings.
Currently Google is located in St Giles, near Tottenham Court Road, with other offices in Victoria.
Construction will not start until 2013, Google said.
It will move out of those offices and into the new King's Cross complex when the site is finished in 2016.
The King's Cross Central development is a 67-acre project in total, which will be made up of shops, homes and offices.
It is built on what used to be a goods yard for fish, coal and gain, according to the BBC.
Reuters said that its neighbours will include the French bank BNP Paribas and a cultural centre run by Aga Khan, spiritual leader of Ismaili Muslims.
"This is a big investment by Google. We're committing further to the UK, where computing and the web were invented," said Matt Brittin, Google's VP for northern and central Europe.
