The foundation of the ring-shaped building has been completed for several months now, with multi-level structural components now going up. Work on the parking structures is progressing, and the auditorium, where Apple will host events, is also taking shape. Much of the auditorium and the available parking will be below ground. Next to the parking structure and the auditorium, work on the Tantau development has begun, where research facilities will be located.
When completed, Apple's campus will feature a massive 2.8 million square foot ring-shaped main building, an underground parking lot, a 100,000 square foot fitness center, a 120,000 square foot auditorium for hosting events, and as we learned earlier this week, a visitor's center complete with an observation deck, cafe, and Apple Store.
The entire campus will be covered with hundreds of trees and orchards, and inside the ring, there will be a central garden with outdoor dining areas for employees. According to the most recent update from the City of Cupertino, Apple is still on track to complete construction at the end of 2016.
