Apple is planning to build a new 50-acre campus near its current headquarters in Cupertino, California, company chief executive Steve Jobs said yesterday. “What’s happened at Apple is that our business has basically tripled in the last five or six years,” Jobs said at a Cupertino city council meeting. Apple “has gone from $6 billion in sales to $20 billion in sales,” Jobs said. “We’re pretty thrilled. Since we’re your largest taxpayer, I thought you might be happy for us.” Jobs said it could take three to four years to design and build the new Apple headquarters, which could accommodate 3,000 to 3,500 employees. Jobs said that, in addition to its present Cupertino campus, Apple employees are spread among 30 other buildings in the city. “We’ve rented every scrap of building we could find in Cupertino,” Jobs told the council.
