In September of 2013, Facebook broke ground on its giant new campus – the one designed by Frank Gehry. The new 433,555 sq. ft. building is expected to be filled with some 2,800 Facebook employees. It also features a giant rooftop space – a park and a garden, complete with a bunch of solar panels.

Well, Facebook just moved in.

“Our goal was to create the perfect engineering space for our teams to work together. We wanted our space to create the same sense of community and connection among our teams that we try to enable with our services across the world,” said Mark Zuckerberg. “The building itself is pretty simple and isn’t fancy. That’s on purpose. We want our space to feel like a work in progress. When you enter our buildings, we want you to feel how much left there is to be done in our mission to connect the world.”

Ok, let’s see how it looks.

Exciting opening day at @Facebook's new office building. This is the entrance I'll walk through on my way to my desk. Beautiful views everywhere. #MPK20 #MPK20FirstLook #Facebook

And a giant rooftop park:

Our new office has a 9 acre #rooftop #park, which is basically 7 football fields. It's like a cross between The High Line in NYC and The Getty Center in LA. #unreal #frankgehry #menlopark #siliconvalley #landscape #roofgarden #mpk20 #whereiwork
