Google's new London office is ready to house several hundred of the company's staff.

Around 800 engineers are moving into the building at 6 Pancras Square in King's Cross on Monday, with another 2,000 staff expected to move in over the course of the year. Only five floors of the building are finished but Google expects all 11 to be complete by October.

The staff at 6 Pancras Square will work on some of Google's best-known products, including Android, the company's mobile operating system, and YouTube.

They'll be given free food, access to a 90m running track, massages, and cookery classes from a chef that used to work with Jamie Oliver.

Business Insider was given a tour of the office last week by Google real estate executive Andrew Martin and Allford Hall Monaghan Morris (AHMM) architect Steve Smith. Unfortunately, we weren't allowed to take photos but Google has sent over a limited selection that we can show you.

The 11-storey office has been leased by Google from BNP Paribas Real Estate, as the search giant stalls on a new £1 billion UK headquarters that it said it would build on a plot of land less than 200 metres away. Google said in 2013 that the new UK HQ would be ready by 2016 but the initial plans were scrapped for being "too boring" and the company is yet to start building.

Google has quietly snapped up several other properties in King's Cross, including the building next door (7 Pancras Square), which is home to the company's AI research lab, Google DeepMind, and a mystery property called "S2," which is yet to be built.
