Originally scheduled for completion in 2015, Apple has been forced to push back its Campus 2 move-in date until the summer of 2016. When the campus was announced in 2011, the project already had a budget of $3 billion but that number has reportedly risen to over $5 billion as Apple moves ahead with development of what Steve Jobs said would become "the best office building in the world" — thanks to its curved glass exterior and energy-efficient design. Apple says that its development schedule "may be modified to meet [its] business needs" moving forward, so that may not be the last of its revisions. Despite these early setbacks, Apple is focused on opening its circular 2.8 million-sf building within three years, allowing it to hold more than 12,000 employees.
Apple will delay the construction of a secondary, 300,000-sf research and development building on its "spaceship" campus in an attempt to drive down the cost of developing its new headquarters. In a filing with the City of Cupertino, Apple said construction of the office building on North Tantau Avenue will now commence as part of Phase 2 of its campus development, a delay that will see work begin once its iconic spaceship building has opened in 2016.
