Deck Railing in Taylor Mill, KY

Taylor Mill (ZIP 41015) sits on rolling country, and behind a great many of these houses the ground falls sideways instead of away. That does something to a guard that people notice without being able to name it: the railing is dead level and the ground under it is not.

A cap is level because it has to be. Ground on a cross-slope can easily drop two or three feet from one end of a thirty-foot run to the other. So the gap between the cap line and the grade widens the whole way along, and the guard appears to rise out of the ground as you walk the deck. At the high end it is a low edge with the lawn close underneath. At the low end it is a real barrier standing well clear of anything. It is the same guard at the same height off the deck, and it reads as two different things.

That is worth designing to, instead of discovering. The low end is where people lean hardest, because it is the end with something to look over, so the post spacing comes in there and stays wider where the ground is close. The infill can do the same work: keeping it most open at the low end gives you the outlook the fall creates, and a heavier section at the high end where you are almost at lawn level closes the deck off from the neighbors without costing a view. And where the guard requirement itself starts partway along a run, we mark that on the drawing so the change happens at a post and looks intended.
