I would like to provide a side with firm width, but contents were to go over the entire height. An example like I it my is to be seen on schleife-1.de/. Unfortunately I cannot find such a layout in CSS Sculptor2.
From the example you have provided, it looks like you can just use the 1ColumnFixed layout. You will then need to add margin the content div (top, right, left and bottom), and then add a div to the content area. This should give you the result you are looking for.
