Apple Park

Located in Cupertino, California, Apple Park serves as the global corporate headquarters of Apple Inc. Conceived by Steve Jobs and designed by British architectural firm Foster + Partners, the development cost an estimated 5.00 billion dollars to construct between 2013 and 2017.

The structure features a continuous circular facade fitted with the world's largest curved structural glass panes, measuring up to 47 feet long. Powered completely by renewable energy, the campus features a 17-megawatt rooftop solar panel array, one of the largest on-site solar installations in the world. The grounds integrate the Steve Jobs Theater with a carbon-fiber roof, a 100,000-square-foot fitness center, secure research labs, and an interior central courtyard planted with thousands of drought-tolerant native California fruit trees.
