This aerial photo gives you a sense of how big Facebook’s one-room HQ is

Facebook has moved into its new headquarters in Menlo Park, California and, as you can see in the photo above, it’s not exactly small. That scale becomes even more impressive when you remember that it comprises a single room.

In a Facebook post, founder and CEO Mark Zuckerberg says that the goal with the new building was “to create the perfect engineering space for our teams to work together”.

The idea, he says, is for the space to build the “same sense of community and connection among our teams that we try to enable with our services across the world”.

According to his hoodiedness, the building is the largest open floor plan in the world. He adds though that there are “lots of small spaces where people can work together”.

Oh and that rooftop garden you can see in the photo? Turns out it’s actually a nine-acre park “with walking trails and many outdoor spaces to sit and work”.

“The building itself is pretty simple and isn’t fancy,” says Zuckerberg. That’s apparently 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,” he writes.
