Facebook employees have moved into a huge new building in Menlo Park, California, with about 430,000 square feet of interior space. It features a rooftop garden that has been likened to Manhattan's High Line park. Around 2,800 employees will work on the new campus.
The building was deigned by Frank Gehry, the architect best known for undulating titanium-clad masterpieces like the Guggenheim Museum in Bilbao.
Mark Zuckerberg said: "Our goal was to create the perfect engineering space for our teams to work together. To do this, we designed the largest open floor plan in the world – a single room that fits thousands of people. On the roof is a nine-acre park with walking trails and many outdoor spaces to sit and work."
The social media giant hasn't released any official interior photos yet, but it invited Instagram users to come and poke around the new campus. See the hashtag #MPK20firstlook for more.
