The construction on Facebook’s massive Menlo Park campus expansion has begun.

The company has just broken ground on the second campus, which will be located across the street from the current campus. The 22-acre West Campus will house the new 433,555 sq. ft. building, which was designed by renowned architect Frank Gehry. It’s expected to be filled with some 2,800 Facebook employees.

The project was first announced in August of 2012 and approved by the Menlo Park city council in March.

“It will be a large, one room building that somewhat resembles a warehouse. Just like we do now, everyone will sit out in the open with desks that can be quickly shuffled around as teams form and break apart around projects,” said Facebook Environmental Design Manager Everett Katigbak when the project was approved. “There will be cafes and lots of micro-kitchens with snacks so that you never have to go hungry. And we’ll fill the building with break-away spaces with couches and whiteboards to make getting away from your desk easy.”

Eco-friendly is the reported theme of the new campus – complete with lots of trees and a rooftop garden. It’ll also receive a bunch of new solar panels:
