Report: Facebook plans to expand new headquarters

(AP) -- The first Facebook employees are just getting settled at the company's new Menlo Park, Calif. headquarters, but the online social network is already talking about expanding.

The San Jose Mercury News reported Monday that Facebook has filed plans to build a second campus across the street from the complex it acquired from Sun Microsystems.

Menlo Park development services manager Justin Murphy tells the newspaper that the move suggests Facebook will quickly outgrow the 1 million square foot Sun campus, which can hold up to 3,600 workers. Facebook has had 1,500 people working at its old Palo Alto headquarters.

The company does not plan to start work on the West Campus until late next year, but has told city officials it wants approval to eventually house 9,400 employees at two complexes that will be joined by an underground tunnel.
