Earlier this week, Steve Jobs explained Apple’s plans for the 98-acre space recently purchased from Hewlett-Packard by the Cupertino City Council in California. A new 4-story building, shaped like a huge donut and large enough to house 12,000 employees, would be completed by 2015.

Jobs plans to improve the grounds around the futuristc-looking campus by transforming the current 20% landscaping into 80%, with twice the amount of indigenous trees and mostly underground parking.

The campus would use its own on-site energy facility, generating power with natural gas and other clean methods, and using the Cupertino electricity grid only as a backup. You can watch Steve Jobs’ 21-minute presentation to the Cupertino City Council in the video below:
