Google has completed a £1 billion (€1.2bn) property deal to move its UK headquarters to a site in London’s King’s Cross area.

The US Internet giant and owner of YouTube has purchased a 2.4 acre site between King’s Cross and St Pancras stations and plans to build a seven and 11 storey complex due to be complete in 2016.

Google already has two central London offices – one in Victoria and one on St Giles High Street – from where staff are expected to be relocated.
