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.

I was very honored to be invited by @facebook to be one of the first to see the new addition to their headquarters, a beautiful futuristic building designed by famed architect Frank Gehry, who is responsible for the design of the Walt Disney Concert Hall, the Guggenheim Museum in Spain, and many other famous structures throughout the world. The space was vast and colorful, filled with art installations, themed work spaces, and a 9-acre sustainable garden on the roof. Facebook worked with 15 different artists who are a part of their local residency and each piece of art inside was created on site with the intention to reflect Facebook's culture and function as a social media. Stay tuned for more pictures! #MPK20firstlook

Frank Gehry is a genius, even in the way he designs staircases, with three story windows flooding light into the building.

Last night @facebook invited me and some other local instagrammers to get first look at our new Frank Gehry designed building (yay I get to work in it!) It's striking one floor open workspace is covered in local artists murals, insane skylights and windows and is topped off with a 9 acre green roof that's basically a gigantic open park! Here's a look down the geometric staircase in one of the two story high lobbies. I'll be posting a handful of shots today from the private tour! 😍 #MPK20firstlook #vscocam #MPK20
