This page uses header template #4 which is made up of a single row. The logo, site title, and site description are located to the left with a menu location and widget area to the right.
Don’t forget, header templates are dynamic so you can configure each one to use different menus and widgets. Also, if you don’t define anything to display in a particular row then it isn’t displayed.
This means all rows are optional allowing even more flexibility in how your header looks.
