The City of Cupertino has released more information and images of Apple's planned circular office building - widely described as looking like a UFO.
The planned Campus 2 consists of a four-storey, donut-shaped glass building on 150 acres just east of its present headquarters, part of which was recently bought from Hewlett-Packard.
It's expected to have around 2.8 million square feet of internal space, and will house around 13,000 staff. Last month, shortage of space forced Apple to lease 373,000 square feet of office space elsewhere in the city.
There's be a 1,000-seater auditorium, 300,000 square feet of research facilities and an on-site natural gas power plant. There'll even be apricot orchards.
The City of Cupertino is now around halfway through its detailed planning review process, looking at the environmental impact of the development - aspects such as traffic, noise, and air quality.
It's highly unlikely to be refused, with Mayor Gilbert Wong saying in June: "There is no chance that we're saying no."
The first ground is expected to be broken next year, with completion scheduled for 2015. Architects Foster & Partners are working with ARUP North America and Kier & Wright, a local engineering firm.
