In order to place custom content to the right of the tab headers you could use the AdditionalContent property and place the visuals you need.
Another approach would be to shift the TabControl a bit to the top (for example using negative margin). This way the TabControl could be aligned with the custom content but you would have to take care about this alignment during resize.
Personally I would prefer using the AdditionalContent property should it meet the requirements.
