Facebook Moves into New Headquarters with the "Largest Open Floor Plan in the World"

Earlier today, Facebook founder and CEO Mark Zuckerberg posted an announcement onto his own Facebook page that the company had moved into its brand new, 430,000-square foot Frank Gehry-designed headquarters. In the post, Zuckerberg offers a photo of the building from above, showing off its 9 acre green roof, with a promise of interior images - of what is essentially the building's giant, single room - "once we’re fully unpacked."

That interior, big enough for 2,800 of Facebook employees plus room for growth, also played host to some of Instagram's most popular photographers to preview the space - see a selection of their images after the break.

Frank Gehry is a genius, even in the way he designs staircases, with three story windows flooding light into the building. A photo posted by Andrew Blotky (@andrewblotky) on Mar 30, 2015 at 9:58am PDT
