Back in 2011, Steve Jobs said that Apple's new headquarters would be "a little like a spaceship." In 2017, Jobs's vision is close to becoming a reality.

New drone footage shot by videographer Matthew Roberts gives a good glimpse at how the new campus is taking form: huge, doughnut-shaped, and actually very much like a spaceship. There's still work to be done, but the site is starting to look much more like a finished product than a concept.

As recently as last year, Apple CEO Tim Cook told employees the campus could be ready by January, according to 9 to 5 Mac. While it doesn't look like that will happen--the main building is not yet complete and the site isn't yet paved or landscaped--it's certainly close.

Also yet to be finished are the solar panels that will cover the majority of the main building's roof. The video's captions estimate the installations are about 65 percent complete. Apple has said the building will be 100 percent reliant on sustainable energy, which could save the company money, since renewables are now in many cases cheaper and more economically stable than fossil fuels.

When the Cupertino campus is finished, it will house around 13,000 employees. Apple started listing permanent jobs for work at the 176-acre site last November. The main building is nearly a mile in circumference. When landscaping is finished, the campus will contain 3,000 trees.

British architectural firm Foster + Partners, the team behind the design, previously worked on London's Wembley Stadium and Millennium Bridge as well as New York City's Hearst Tower.

Campus 2, as it's called, will also have a 1,000-seat, partially underground auditorium that's separate from the main structure. That building is expected to host Apple's product unveilings, the next of which 9 to 5 Mac suggests could be as soon as March.

Apple's current headquarters will remain open even when the new campus opens. The project, which will cost an estimated $5 billion, has been under construction since 2013.
