Facebook is opening a new London office just down the road from Google's new UK headquarters in King's Cross, according to Property Week.

The trade magazine claimed Mark Zuckerberg's social media network is expanding from Covent Garden to the new Regents Place development next to Euston Station where Twitter is reported to have already taken 18,000 square feet of office space.

The site is roughly one mile from Google's new £650 million office, which won planning permission this month despite boasting a running track and a swimming pool on the roof.

Facebook's office is reported to be taking 85,000 square feet of the 320,000 square feet on offer. If this proves to be true then it will be just shy of the 90,000 square feet Google is creating for its new UK headquarters office, which will become home to 5,000 Googlers when it opens in 2015.

Several people working in London's tech scene now consider King's Cross to be within the boundaries of Tech City, including outgoing deputy CEO of the Tech City Investment Organisation, Benjamin Southworth, and founder of Innovation Warehouse, Ami Shpiro.

Facebook was not able to comment on the report.
