Horizontal wood fencing
This is the same horizontal extension above the privacy fence but the proprotions here are not what we want as the top part is just too high and the vertical supports are hidden in the bottom part of the fence and we would probably want fence sections instead of long runs of wood as are in this image, but this is still the general idea that I had about crowning a privacy fence with a run of horizontal panels.
The one thing I like about this photo is the extensions along the top of the walls and would like something like that along the top of a standard height wood fence to extend the height and privacy of the fence and provide that horizontal element. So the fence posts would be high enough to accomdate this on top of the privacy fence. I envision something even a little higher or at the top boxed in with a slightly thicker wood at the top and bottom perhaps making a box with the horizontal strips inside. That these rectangular panels would match the sizing of the fence panels below.
