Apple is a stupendously wealthy company, and its in the middle of building a new corporate headquarters befitting of that success. The Norman Foster-designed Campus 2 — commonly referred to as The Spaceship due to its distinctive circular design — will add 2,800,000 square feet of office space to the companys Cupertino, California operations, and it will hold more than 12,000 employees. It will also be entirely powered by renewable energy, thanks to one of the largest solar arrays ever designed for a corporate campus. Apple co-founder Steve Jobs oversaw the buildings design before his death, but the campus has struggled to get off the ground.
