Apple may have just closed a deal to build a second new California campus, but the company is still hard at work on its original “spaceship” headquarters. A new drone video shows us how far along the original spaceship campus is coming.

The latest 4K drone video mostly focuses on the main ring structure. The building is really starting to take form, which drives home just how massive Apple’s new campus will be. Once complete, the office building will feature continuous floor-to-ceiling glass windows all the way around. In the middle the company is planning a forested area where employees can relax and eat meals.

You can also see a long parking structure close to the office building. Finally, it looks like construction on Apple’s underground auditorium has kicked off as well. The new space will hold up to 1,000 people for future events, and features a modern glass entrance above ground.

Apple isn’t expected to finish construction on its new campus until at least late 2016, and the company’s recent decision to fire its contractors could slow the process down even more. The project is estimated to cost roughly $5 billion, though it may already be about $2 billion over budget.
