For a design-obsessed company that surpassed Exxon Mobil to become the world's most valuable company (at least for a couple of hours last week), a campus headquarters full of relatively nondescript office buildings isn't going to cut it. As Steve Jobs first presented in June, Apple will vacate its current Infinite Loop headquarters in Cupertino, CA, and move just a few blocks away to a new "giant, space-ship shaped" campus, as Jobs himself described it. A few days ago the city of Cupertino released new renderings of the building, and the images are stunning. The circular four-story structure, measuring approximately 2.8 million square feet and occupying 175 acres of land, will hold a 1,000-seat auditorium, a fitness center, 30,000 square feet of research space, and an underground parking structure. 12,000 employees will call it home upon its scheduled completion in 2015. Check out more images of the mothership after the jump.
