Office spaces have never looked this enticing, especially for workers at Google, Apple and Facebook which are building massive campuses designed to provide not only a place to work but also a place to live for thousands of their employees.

Mashable provides A Peek at Google's £1B Upcoming 1-Million-Square-Foot Office in London.

The upcoming London office of the tech giant is scheduled to open in 2016. The Web site said it will feature an open-air swimming pool, indoor football pitch, climbing wall and a roof garden that provide views of the Kings Cross station.

These amenities support a work-life balance for Google's employees as well as encourages healthier and environment friendly lifestyle by providing for a bicycle store room with showers and lockers for workers who want to bike their way to the 1-million-square-foot office situated on 2.4 acres of lot between the Kings Cross and St Pancras rail stations.

Google announced the acquisition of the property in January, one of the largest commercial property purchases in Britain initially costing £650 million but would be worth £1 billion once the complex is built and the site developed.

Mashable theorises that Google decided to build the future grand office complex as a form of avoiding taxes in the U.S. for income earned outside the country while at the same time offering a workplace that will entice employees to stay with the tech giant.

The lucky London architectural firm that got the project to build Google's London headquarters is Aliford Hall Monaghan Morris. Simon Aliford of the architectural firm said, quoted by Mashable, "The idea is that the people who are in the building - not the tenant but the actual staff - need to be attracted to the building. They need to like the community of the building."

It is not just the building that would be Google's attraction to its UK employees but also the neighbourhood which includes the Central Saint Martins art school, the Francis Crick Institute biomedical research centre, the British Library and newspaper Guardian's office.

Mr Aliford added that the building, constructed to last a century, will be flexible with the edifice serving as the theatre, the auditorium as the stage set and the meeting rooms and furniture as the props.

He said the idea is to create a dynamic, flexible space defined by its occupiers, not the other way around.

It can accommodate 4,500 Google employees, more than double the current number of its current London workers housed in two offices at Victoria and off Charing Cross Road.
