Apple's new $5bn headquarters to open in April

Apple has announced that it will begin moving staff into its new $5 billion (£4 billion) headquarters in April, opening a futuristic campus that has been more than six years in the making.

The company said that a new 1,000-seat auditorium at the facility will be named the Steve Jobs Theatre in honor of its co-founder, who died four months after he presented plans for the spaceship-spaced building and tree-filled park in 2011, his last public event. 

The donut-shaped building will be the centre of the 2.9 million "Apple Park" in Cupertino, California, near Apple's current headquarters. The building was originally scheduled to open in 2015 but like many large construction projects faced budget overruns and delays.
