No, I think that's a bad idea. You're creating potential problems with rot, and so you're having difficulty accessing the fence for repair. It's only a 30 cm space. If you have a project you're working on, be sure to post an update.
I'm sure our members will be happy to see what you're creating. Please let me know if you have any questions, Mitchell. The only other option I can think of is to build a lightweight roof fence with a door near the retaining wall that limits access to the gap. This way, no one will be able to access the retaining wall area except you. It also covers the Colorbond fence at the same time.
Since the neighbors' fence is lower than my retaining wall, I was looking for ideas to fill in the hole, so that pests would not enter, etc. or the children would accidentally fall. In this way, the fence will not weigh more and both wooden products are compatible with the treatment of the fence. The result will be a long section of vertical gardens where you can grow your own food.
Otherwise, this is a very artistic way of covering the fence. The gap between the fence and the retaining wall is a nuanced element in landscape architecture, harmonizing structural integrity, security, functionality and aesthetics. We're talking about fences that are great, fences that keep privacy, fences that make your backyard feel special. I am also sorry to have mentioned that corrugated material is the retaining wall and I suppose that until recently it served as a border fence, which is very common in Perth. The intention is to use the space between the wall and the dividing fence as a planter on both sides.
In New South Wales, the Dividing Fencing Act has an exception for retaining walls that are necessary for fence support. And when it comes to durable, affordable, and customizable fencing options, it's hard to beat a classic chain-link fence. The most complicated option is to dig into the ground and rebuild the retaining wall so that it is closer to the neighbor's fence, making the space between them as small as possible.
