It’s been billed as ‘the best office building in the world’ – and, so far, it seems Apple’s new HQ is living up to the hype. These incredible images show exactly what the firm’s new Apple Campus 2, in Cupertino, California, will look like when completed in 2015. Appearing as a giant saucer, amidst a dense jungle of trees, the 175-acre Silicon Valley site near the 280 Highway will house 13,000 staff. Dubbed ‘The Spaceship’ because of its 360-degree curved glass fronted walls and central courtyard, it will also contain a 1,000 seat auditorium, a gym and 300,000 square feet of ‘research’ space. The 2.8 million square foot HQ will have underground parking, so that 80 per cent of the site can be covered in trees – and clean energy sources, primarily natural gas, will provide its power. The local energy grid will only be accessed in emergencies. Apple CEO Steve Jobs said his firm was “growing like a weed” and added: “We do have a shot at building the best office building in the world. I really do think architecture students will come here to see this.”
