The city of Cupertino revealed more details about Apple’s planned new spaceship-shaped campus, including higher resolution renderings along with information about the facility’s environmental impact.
Apple’s planned spaceship campus in Cupertino
According to the city, Apple Campus 2 building will be four stories tall and include 2.8 million square feet of space in the ring-shaped structure. It will include room for some 13,000 employees, with a 300,000 square foot research facility and a 1,000 seat auditorium. As Apple CEO Steve Jobs said earlier this year at a city meeting, the new campus will include underground parking.
Apple will be building its own power center to provide electricity for the campus and will require little supplemental power from the local grid.
According to the city, Apple will be restoring some of the area’s native vegetation with the assistance of arborists from Stanford University.
Once the new campus is complete, Apple will use the location along with its current headquarters on Infinite Loop. The project is expected to be completed in 2015.

Should Apple ever need to greatly expand this facility, I think its current design facilitates building many massive extensions, without needing to change in any way at all, this facility’s outward appearance or the space & ecology of its parkland/vegetation inside & outside the ring, thanks to the existence of its subterranean parking (+/- power center) level.
Apple could eventually dig/tunnel out & build beneath its trees & parklands new underground extensions as far laterally &/or medially (and perhaps even straight down beneath the ring) as it may want to reach, so long as the soil, left in place above those new caverns, still manages to support its life well. And the entire spaceship facility would always be all connected by very proximate underground halls & passageways, no matter how wide/deep any new subterranean extensions may excavate, again & again, limitlessly, thanks to the presence of this underground (“parking”) floor serving as a terminal to those future radial subterranean extensions.
For instance, Apple thus could easily build another server farm there as big as its NC facility, which should need no significant internal or external energy supply for cooling because free geothermal cooling/heating from the earth beneath it should be more than adequate for the largest server farm’s needs, and all without changing the Cupertino spaceship facility’s surface profile.
And if Apple thinks it also might ever want to build higher, it should now be reinforcing its steel skeleton’s foundation strong enough to support double or quadruple (or octuple, etc.) the number of its currently-planned floors.
