Summary: Backyard privacy does not need to be an unattractive and solid windscreen, but it can be a beautiful and breezy decorative block wall. You can add it to an existing patio foundation as a wall, or build it on its own footing as a free-standing fence.
Note: If you are planning to build a wall or fence taller than 3 feet, you may need to get a building permit for it depending on where you live.
If you get off on the right foot with a proper foundation, your privacy screen will look fantastic. If you are not going to place your privacy wall on an existing concrete patio slab, you will need to create one specifically for the wall. This is done by simply digging a 10 inch wide by 7 inch deep trench that is the length of your proposed wall.
