Apple's new Cupertino, California HQ, currently under construction, will sit on a 176 acre campus and features a circular "spacship" main building.
Steve Jobs presented the plan to the Cupertino city council in June 2011, four months before his death.
The four-story circular headquarters will be one of the largest buildings in the world.
Designed by Norman Foster's Foster+Partners, it offers 2.8 million square feet (260,000 square metres) of space for 14,200 Apple staff (all told, Apple directly employs around 73,000).
The design allows for 10,500 parking spots, most underground.
Apple spent $US160 million on the land for its new campus.
The cost of the spaceship building has been estimated at $US500 million (Apple has yet to put a public price tag on the building, instead lumping it in with $US3.4 billion of capex that includes server farms and other projects).
