Apple’s aptly-dubbed “Spaceship” campus is well on its way to completion and now, following a look at the progress back in March, comes the best view yet of the ongoing construction. Captured in 4K ultra high-definition via drone, the video offers a lengthy look at the Cupertino site — a 2.8 million-square-foot behemoth that will ultimately house over 12,000 employees. Check out the video above for a look at the progress of the underground auditorium, R&D facility, traffic tunnels and “Spaceship” itself.

Apple’s second Cupertino campus is currently on track to open in 2017.
