This new drone footage shows that Apple’s ‘spaceship campus’ still has a long way to go

Drone footage surfaced today of Apple’s new Cupertino headquarters, which has been under construction since 2013.

Apple Campus 2 is part of the legacy of Steve Jobs, who originally planned the campus, which is supposed to accommodate 13,000 people, on its 176-acre site.

“It’s a little like a spaceship,” said Jobs when he proposed the new campus to the Cupertino City Council back in 2011. “We have a shot,” he said, “at building the best office building in the world.”

Last year, Tim Cook told employees the new campus would be done by January 2017, according to 9to5Mac. Looking at the footage that came out today, it appears there’s still a lot of work to do.

The latest video shows new landscaping and earthwork across the entire campus. Captions by Matthew Roberts, the videographer behind the drone footage, note that there are also windows now covering the new auditorium under construction. The on-campus auditorium will seat 1,000 people, according to plans submitted with the city of Cupertino.

The central building is a four-story ring with a giant park proposed in the center, filled with hundreds of fruit trees; the new footage shows some unplanted trees sitting in the middle of the area inside the building’s open center. The new campus will also include a 100,000-square-foot workout facility and a huge underground car park, leaving space for miles of cycling and walking trails.

Apple aims to make the campus completely sustainable on renewable energy. The drone footage reveals some of the 700,000 square feet of rooftop solar panels being installed on the main building, which also features the largest piece of curved glass in the world. Roberts estimates that the solar installation of the roof is 65 percent complete.
