Apple Campus 2 is an upcoming future headquarters of Apple Inc. in Cupertino, California. It is under construction and is expected to be completed by the end of Q1 2017, and start to be occupied in early 2017. On June 7, 2011, Apple’s then-CEO Steve Jobs presented to Cupertino City Council details of the architectural design of the new buildings and their environs.
It is circular in shape, resembling the classic idea of a flying saucer spaceship that has just landed. It is located on suburban site now totaling 176 acres (71 hectares) and is planned to house up to 13,000 employees in one central four-storied circular building of approximately 2,800,000 square feet (260,000 square meters). Steve Jobs wanted the whole campus to look less like an office park and more like a nature refuge. Eighty percent of the site will be green space planted with trees and plants indigenous to the Cupertino area.
