X-cart will list the subcategories by default. If you make a subcategory of sheds then it will by default be shown at the top of the "shed" listing. By default the text is on the small side, but as always this can be changed. The subcategory listing appears a little on the wide side to me so I cut it in half and used the place where the category icon would be to put in some text. I imagine with a little work you could put a "featured product" in there instead. In that way it would look similar to your example.
