Google has unveiled the plans for its new £650m UK headquarters after submitting a Reserved Matters application to Camden Council.

The new one million sq ft google campus at King's Cross central which will house all London-based Google staff, who will relocate from current premises in Victoria and Holborn, will be the first purpose-built headquarters built by Google anywhere in the world. It is estimated that 35,000 people will be working on the 67-acres King's Cross development once the entire development is completed.

Dan Cobley, Google UK's Managing Director, said: "Building our new headquarters in King's Cross is good for Google and good for London. We're committed to the UK and to playing a role in the regeneration of this historic area."

Google acquired the long lease of the 2.4 acre site from King's Cross Central Limited Partnership (KCCLP). The headquarters will contain 725,000 sqft of office space and around 50,000 sqft of retail space at ground level in buildings ranging from seven to 11 storeys high which will overlook Regents Canal.

David Partridge, director of Argent (King's Cross) Ltd, said: "This project is hugely important for King's Cross and underlines our commitment to support world class design. It will attract further investment into the wider area and act as a catalyst for the local economy and the community which we are building."

If planning is approved, work will commence early in 2014 with a completion date targeted at the end of 2016 or early 2017, with the construction works expected to generate 1,500 jobs.
