The City of Cupertino has released a detailed floor plans of Apple's 20,000 plus person super-structure "Mothership" HQ. The documents embedded below are entitled "Intro, Site Plan/Landscaping, Floor Plans and Renderings."
The building, dubbed "the Mothership" was announced by Apple CEO Steve Jobs on June 7th, just days after WWDC earlier this year.
Jobs called the new building "a spaceship" and said Apple will use its experience in building retail store masterpieces to construct this "architectural landmark". Parking underneath, the building would perhaps be used for events like the WWDC - Jobs mentioned that it would have a large auditorium and a single cafeteria [below] that could seat 3,000 at a time.
Cupertino's Mayor went on record a few weeks later saying "there was no way they weren't going to approve the deal".
The massive building's plans detail the main building and a mostly subterranean adjacent parking structure with Solar roof (below).
Here're some screenshots from the presentation:
