The project represents Facebook's first customized campus -- its current home was previously occupied by Sun Microsystems. It will house 3,400 engineers in a single building with reconfigurable work and meeting space and a garden that extends from around the building to cover the entire roof of the structure, according to Facebook.

It will be situated on ground already owned by the social networking site operator that sits across the street from its current campus in Menlo Park. A tunnel already connects the two pieces of ground and that will be used by staff moving between the two.

Dubbed Facebook Campus West, initial plans called for four separate buildings but Gehry consolidated these into a single structure that manages to avoid the look of a warehouse or hangar by having angled walls that zig-zag along the length of the building.

Photographs of models of the new building released by Facebook on Friday show hundreds of desks occupying the interior broken up by meeting rooms and offices -- effectively buildings within the building. These interior buildings are oddly spaced and angled to match the exterior and will probably mean each area inside the building doesn't feel too big.

To the northern side of two buildings are what appear to be water slides -- something that wouldn't be totally out of place in the Internet corporate culture of Silicon Valley -- but their actual purpose is less exciting. They are curving walkways that will take people from the office space to the parking structure that will sit underneath the building.
