can I make a tall verticle module???

I want to make a long module where I put the navigation. This would be about a span3 and the rest would be span 9. Then when it goes to tablet or small it would collapse the nav area and make the rest span12.

I saw this site (not T3) but was wondering if I could do that.

As I look at the layout in the T3 configuration I don't see how I can set that up.
