How do I get a clean uncluttered home screen as shown in the iPhone 6 ads?

[iMore Question]

In the Apple stores the walls are covered in huge images of iPhone 6, and all images show a clean uncluttered home page, without those '4 annoying apps' across the bottom of the screen.
How can I achieve this?
Apple has done it in their advertisements.

You can long press on any app to remove them.
However, you will end up with a band at the bottom that, in my opinion, looks worse.
