First Look: Facebook's Amazing New Campus

Facebook (FB) already has 2,000 employees at its headquarters in Menlo Park, Calif. But it's preparing for a major expansion. Eventually, its current location—the East Campus—will hold 6,600 employees. Another 2,800 will occupy a second site, the West Campus, across the Bayfront Expressway.

Facebook has hired Frank Gehry's architecture firm, Gehry Partners, to design a new, sprawling office building which will house those engineers in a big, open space, with walls cleverly angled so the insides don't feel oppressive.

Here are some models and drawings which give an idea of Facebook's new home.

rows of desks and meeting rooms clustered throughout the building. You'll be able to walk from one end to the other without passing through a door. Note the looping ramp in the upper left—that gets you from the basement to the first floor to the roof.

The roof will be planted with grass, trees, and a vegetable garden. It's not just pretty—green roofs cut heating and cooling.
