Vertical section possible? Like the Daily Mail side bar of shame

Sections stack horizontally. But how do I create a vertical section to run alongside stacked sections?

Like Section 3 here:
Side by Side sections

The Daily Mail website is a master of this layout - with its "side bar of shame running down the side of the main panels.

Any ideas?!

Thank you!

Here is how my site looks right now. All stacked sections. I want to put new things on the right hand side.

I’m sure this could be done with a grid, setting the top right section to span two rows.
