Google's huge London property empire is starting to take shape

Google is looking to expand its UK workforce from around 4,000 people today to 7,000 people by 2020.

The search giant currently has three main offices in London with one in King's Cross, one on Tottenham Court Road, and another in Victoria. It also has a smaller startup space near Old Street known as Campus.

Over the next few years, Google is planning to make King's Cross, a neighbourhood in the north of Central London, its main base in the city, opening a number of new buildings in the area.

Here's a look at some of the properties that Google is planning in King's Cross and some that it already has in the area and across the rest of London.
