Washington, Dec 20 (IANS): Facebook has announced that its final wave of employees have moved into its new headquarters in the one million-square foot Menlo Park city of California.

The world's largest social network is now officially headquartered at 1601 Willow Road in Menlo Park, Xinhua reported.

The new campus consists of 10 eco-friendly buildings with no private offices and cubicles. Over 2,000 local employees moved to the campus from its previous location in Palo Alto, California, US.

"This morning, the final wave of employees walked through the doors of the new Facebook Menlo Park campus," said the company Monday in its official blog.

According to Facebook, the whole campus, featuring hallways with chalkboard paint, is connected through a central courtyard which will have cafes, coffee shops, on-site doctors, and gym after the construction is completed.

The company said the current East campus could hold up to 9,400 staffers one day along with the West Campus that is still under construction.

Facebook noted that it is relentlessly focused on minimising its impact on environment.

It said it has reused as much of the existing structure as possible, noting all the doors on the campus are recycled from those used by predecessors.
