Plot with terrain drop - separating wall neighbors - foundation?

That is an interesting approach! I will check this.

Maybe you are also a bit skilled and could help him a little with his building? - that way you would definitely win over a DIY builder.

SPEAK and point out your CONCERNS. Maybe the penny will also drop for the rag doll

The neighbor has meanwhile dug a trench on my side of the property and started to level the protruding concrete with a demolition hammer, hammer, and angle grinder. In doing so, he has excavated about one meter and, as far as I could see, fully exposed the foundation. Unfortunately, the concerns I raised again were not addressed. On his side, he has prepared four quasi "cantilevers" of the wall at half the height of the wall, using hollow chamber stones + reinforcement with reinforcement under the future garden level, which he intends to pour later for stability. However, I fear that this will be relatively irrelevant to the ground pressure, won't it?

Um, can you sketch that again, maybe also from a top view?

Or post a few photos.

When I read this

If I now remove the approximately 70cm of earth buildup on my side, I expose everything except 30cm of the foundation.

It ultimately means that when the pile of earth is gone and you properly dig the garden there with a spade, you are already undermining the foundation, and I seriously doubt whether that contributes to the stability of the wall.

You probably doubt that with good reason; a loose pile of excavated earth, even at its thickest spot at the base, provides maybe 2° of frost protection for the foundation, certainly not a solid covering. But let's wait for some images.
