I’m just wondering what’s worse, this slapped-up wall or a wire mesh fence with those plastic bands. *scratches head* With a bit of luck, the next storm will knock down both. Then something proper can be built.
To be honest, I have little suspicion from the photos that it is supposed to be finished like that - and recommend a clarification technique called "conversation"
How do you feel about the neighbor?
To be honest, I find the wall an imposition, hardly surpassed in ugliness.
Did he discuss this with you?
If not, the wall is probably your least problem in the long run.
Plant a hedge in front of it?
What is the legal situation? I would like to install a privacy screen. The neighbor is now about 1 meter above my property because he has filled it up to the top. The privacy screen should be 2.50 meters high, right? And it should be more stable than the wall, which I do not trust. A natural privacy screen would also be my preference, but it takes a few years to become dense. I will also plant some greenery. Otherwise, we have a lot of granite and sandstone!
