All of the major landscaping work was completed in 2015.
Now, Apple only needs to finish the building, which it will do by "late 2016," barring any additional setbacks.
Then, it was time to assemble the building's exterior.
The building's structure has been nearly completed, according to the latest aerial image provided to the city of Cupertino by Apple.
According to Seele, Apple's glass supplier, the building will use "something like six kilometers of glass."
Glass makes up the majority of the exterior of Campus 2, and was a major part of Jobs' original design.
Not only will the campus give Apple employees a place to work, but it will include a state-of-the-art auditorium for holding product presentations.
"We’ve got an auditorium, cause we put on presentations, much like we did yesterday but we have to go to San Francisco to do them," Jobs said in 2011.
Here's a peek at some of the plans that Apple is working off of.
This is the most detailed depiction of where everything will eventually end up. Note the fairly large fitness center in the northwest corner of the lot, the ample parking near the freeway, and the corporate auditorium with direct access from the road.
Before Apple purchased the land that it's building its new campus on, it was a campus for Silicon Valley pioneer Hewlett Packard.
HP's advanced products campus was significantly more architecturally conventional than what Apple's building. Apple tore the building down in 2013.
Apple Campus 2 has come a long way since Steve Jobs originally announced the plans for the campus during his last public appearance at a Cupertino city council meeting.
Apple first tipped that it wanted to build a big campus in 2006, before the iPhone came out. But the firm plans that the company continues to follow were revealed in 2011, by former CEO Steve Jobs, in one of his last public appearances, at a Cupertino City Council meeting. "It's a little like a spaceship landed," Jobs said. Watch the video here.
