Privacy screen, what would you do?

If the issue of who installs a privacy screen on their property and pays for it is settled, spending a week there, I might be tempted. My week would be well spent

I think I might need to mention that next door there is a rental house. Surely no one there would build a privacy screen on their own. Although there are long-term tenants, older people, still. The investment remains with us.

I have now taken another photo from our kitchen window. Basically, a privacy screen needs to be installed starting from our house wall.

So the nosy neighbor is on the same side as the playground; the playground (where the little one should be able to get over the fence) adjoins the neighbor's property (?)

On the terrace, this would mostly be possible with more generous height than at the boundary.

Exactly, that is above the playground.

We have also already thought about the terrace, but we actually want to have a pool behind it someday.

but a privacy screen of about 1.80 m directly at the edge of the terrace would probably be best.
The terrace that you see in this picture, however, is not our main terrace. The one that will also be covered and is our main terrace is in the following picture

In the building line?

The terrace you see in this picture is not our main terrace, though. The one that will also be covered and is our main terrace is in the following picture.

They both seem to me to be the same - you should probably add a site plan so that one can get an overall view from above. Google Earth should suffice.

why don't you simply make a mixed hedge with e.g. cherry laurel, golden privet, glossy photinia, Portuguese laurel cherry, yellow and red ninebark and other shrubs? You can also buy shrubs already grown, so you don't have to wait for years. I would rather not take bamboo, Phyllostachys need a rhizome barrier and after some time they are not necessarily really dense at the bottom and Fargesia doesn't look so great in the sun and also doesn't grow that tall.
