The Underground 1,000-seat Theater and The Carbon-fiber Roof

“All the things we have, lined up with what they needed,” Mr. Lynn said. “They will represent a large part of our business.”

Tech companies are nothing new for Cupertino. Apple has called the city home for decades, and Hewlett-Packard had a campus in Apple’s new spot, employing 9,000 people. The surrounding towns have been remade as well in the last decade, as giant tech companies have transformed Silicon Valley’s real estate into some of the most expensive in the country.

But city officials and residents say this project is like nothing they’ve seen before. It is even bringing tourists.

Onlookers snap pictures of the spaceship from the streets. TV helicopters circle above. Amateur photographers ask residents if they can stand on driveways to operate their drones, hoping to get a closer look at Apple Park.

Drone operators want that coveted aerial shot while pedestrians want to get an eyeful of the curved glass building before the headquarters become hidden by a man-made forest.

The main center features the spaceship ring, the Steve Jobs Theater, a 100,000-square-foot gym and a visitors center in a woodland setting with two miles of running and walking paths. An orchard, a meadow and a pond are inside the ring.

“Mind-blowing, mind-blowing, mind-blowing,” the mayor, Savita Vaidhyanathan, said about her visit to the site. “I saw the underground 1,000-seat theater and the carbon-fiber roof. The roof was made in Dubai, and it was transported and assembled here. I love that it’s here and that I can brag about it.” Apple Disrupts Silicon Valley With Another Eye-Catcher: Its New Home
