The Burj Khalifa is more than 160 storeys high, rising 828 metres into the sky.  Here is a video of the crazy bastard working at the very top: http://www.archdaily.com/tag/dubai/

Here's a nice visual reference of the relative heights of these buildings:  http://upload.wikimedia.org/wi.....jDubaiHeight.svg.png
