Another drone has braved Apple’s spaceship campus construction site, and the results are pretty awesome. This is the closest we’ve ever been to the action just as the main structure is beginning to really take form.

The short video offers plenty of flyover shots of the future Apple headquarters in 4K quality. We’re mostly looking at the main donut-shaped structure, which will feature a continuous ring of office space with glass panel windows all the way around. At the center, Apple is planning a forested garden where employees can relax.

The site will also feature a massive new underground auditorium, where Apple will hold future press events for up to 1,000 guests. The entire 120,000 square foot space includes a modern glass entrance above the surface.

Construction on Cupertino company’s new headquarters is expected to wrap up in late 2016, giving Apple staff time to move in before the end of next year. The entire project could cost as much as $5 billion once complete.
