Steve Jobs says he would like Apple to break ground next year on a 'spaceship'-type campus in the company's home town of Cupertino, California and move in by 2015 in a building the iPad-maker's CEO described as having a shot at being the best office building in the world.

Jobs came before the Cupertino City Council on Tuesday to present a series of drawings and plans and take questions for the 155 acre campus just under 40 miles south of San Francisco, touting the company's status as top taxpayer and largest employer.

The campus we'd like to build there is one building. It holds 12,000 people. And it's [a] pretty amazing building, he said. It's a little like a spaceship landed.

The building might hold up to 13,000 if we get a little luckier, he said.

Jobs described the building as a circle curving all the way around with a court yard in the middle.

He said there would not be a straight piece of glass in the building, which builds upon the company's experience in making retail buildings.

We know how to make the biggest pieces of glass in the world for architectural use, he said.

The property will include parking underneath the main building, and a four-story parking structure on one end of the property.

There's nothing high here, we want the whole place human scale, Jobs said.

An energy center would generate power with natural gas and other ways which can be cleaner and cheaper and use the grid as our backup, he said. We think that makes more sense.

Jobs also expressed hope the building could be used as a learning tool.

I think we do have a shot at building the best office building in the world. I really do think architecture students will come here to see this. I think it could be that good, he said.

One councilman raised concerns that the concentration of employees in one building could raise safety issues.

Jobs said the building has to be designed with pretty precise requirements for safety but we'll even go beyond those.

When concern about additional traffic was raised, he said employment would not be increasing much.

It's like 20 percent, he said.

The building will be four floors high, and have over 3 million square feet. A cafeteria on site will accommodate up to 3,000 people at one sitting.

In 2006 Jobs told the Council that Apple had attempted to find cheaper property at other sites, but chose to stay in Cupertino because it found property large enough to stay despite the cost. Over the years it bought property from Hewlett-Packard that was later consolidated for proposed the campus.
