Intercepting higher neighboring plots: L-shaped stones, etc. - Tips

Thanks - so the difference lies in the entire geometry of the component. I can imagine that installing the more expensive concrete blocks requires less effort and thus somewhat relativizes the price difference. The question of price justification is always also a question of perspective – is it the case that there is a surcharge on the mass standard product, or does the mass standard product have a particularly high discount compared to the "normal price" due to mass production? Depending on the viewpoint, either one appears overpriced or the other particularly cheap. As customers, we tend to always see the lowest prices as the standard for comparison.

I suspect that the inverted construction method makes the bricks more expensive because they have to be taller since the lower part of the L is still being built over, right? That means the L has to be set deeper, ergo taller brick...

I suspect that the reverse construction method makes the stones even more expensive because they need to be taller since the lower part of the L is still built over, right? That means the L has to be set deeper, ergo taller stone...

That is probably correct, depending on what I want to cover the feet with on my side. And it makes a difference whether paving, grass, or deeper-rooted bushes are to be placed there.

I can imagine that laying the more expensive concrete stones requires less effort and thus the price difference is somewhat offset.

True. In our case, the craftsman did not charge me extra for the special models of the wall panels. However, I only had very few of the special models and quite a few standard versions.

The area of the picture should now be 1 m deeper again? I don't understand how you want to do that. Is there a site plan from the building application with height information? You can possibly mark the problem there. A section for that is helpful.

I am reluctant to publish the entire site plan here. I ask for your understanding and will also try to provide a cross-section.
The following in advance:
Top edge of finished floor 25.7 m above sea level [müNN]. This will also be approximately the height of the outdoor facilities around the new house.

Area where the employees stand in the picture 26.2 m above sea level [müNN].

The neighboring property is behind the game fence, so at least +1.0 m higher than the 26.2 m above sea level [müNN]. But this is really the worst area. Usually, the height of the adjacent neighboring properties can be assumed to be about 26.5-26.7 m above sea level [müNN].

I hope it is a bit clearer now.
