Apple's space-age future digs

Apple is planning an expansion of its corporate headquarters on a 176-acre plot in Cupertino, California -- a site that was once home to HP and Compaq. This rendering shows the spaceship-like main building, which has 2.8 million square feet and room for 13,000 employees. 

 

Slated for completion sometime in 2016, the new headquarters will offer employees a massive, 90,000-square-foot cafeteria.

This parking garage will have solar panels on top and plants drizzled down the sides
