Google announced that it has acquired all of the Central St. Giles building, where it already occupies a number of floors.

The company has bought a colorful office space in London for $1 billion while it waits for building work on its heavily-delayed U.K. headquarters to be completed.

The Mountain View-headquartered firm employs 6,400 staff in the U.K. and the company has pledged to create enough U.K. office space for 10,000 in the coming years.
