A dark-colored roof, a private jogging path, walkways and modest changes to the additional fitness center are some of the main inclusions in Apple's newly submitted renderings of its proposed 13,000-employee mega-campus in Cupertino, Calif.

The City of Cupertino posted the updated plans of Apple Campus 2 Project to its Web site Tuesday. The new campus is located across town from the company's headquarters and was first pitched to the city council by the late Steve Jobs as resembling a spaceship, according to CNET.

The newly updated plans are huge, more than 40MB PDF files in high-resolution detail. Other key changes include the addition of parking plans for the corporate auditorium and expansion of the corporate fitness center from the original proposal of 25,000 square feet to 45,000 square feet. However, the fitness center apparently loses a floor in the process, as the updated plans show the facility's height at 18 feet instead of the original 30 feet.

The 2.8 million square feet Apple Campus 2 will be surrounded by green space (with 6000 various species of trees) and will be more than four floors high, Slash Gear reported.

The project has perked up much criticism as well. Christopher Hawthorne, the architecture critic for the Los Angeles Times called it a retrograde cocoon and a doggedly old-fashioned proposal, while The New Yorker's architecture critic profiled the project as a gigantic donut that lacks functionality and human scale, AppleInsider reported.

After getting the necessary approvals, Apple hopes to break ground on the project next year and open the facility in 2015. Click on the links below for more details on the updated proposals of the Apple Campus 2.
