Hello Community,
I am looking to add feature wall in front of colorbond fence or at least do timber panels to cover it. Something similar to the picture below

Here is the challenge I have.
1. Cannot dig holes deeper than 300 mm as this is a rocky area and I remember during retaining wall build we had to call bigger machine to break the rock and then drill.
Here is what I am thinking
As seen another projects in the forum, there is a requirement to create frame before hiding anything, hence below is my idea of the frame.
Since I cannot dig deeper i will make concrete column 300 mm above ground as well and may add some steel to add strength

Some pictures of the fence that need to be covered.

Help Required
Is there another simpler way to achieve this rather than doing so much of concreting, i mean can we install panel directly on colorbond fence or may be have some anchots which can sit between rail and panels.
Any ideas ?
Regards
Sach
