ᐅ Plot with a change in ground level – boundary wall between neighbors – foundation?

Hello!
I hope this is roughly the correct section for my question; if not, please feel free to move it.
Situation:
The neighbor’s plot is significantly higher than mine, and their garage was built just 20cm (8 inches) from the property line. Since the development plan actually requires that there be no sudden changes in ground level, the neighbor should have compensated for the height difference with a slope at about 45°. My garden level means there would be a roughly 1.5m (5 feet) wide slope here—of course, at the expense of their plot. So, we agreed that instead of the slope (and demolishing part of the garage...), the neighbor must build a retaining wall on the property line, which also ensures that drainage happens where it’s supposed to.
We have not yet set the final ground level on our side; we plan to lower it by about 70cm (28 inches). Now, the neighbor has dug a trench along the property line, poured concrete into it, and is building a wall on this foundation using hollow blocks that they also plan to fill with concrete later.
If I remove about 70cm (28 inches) of soil on my side, this will expose all but 30cm (12 inches) of their foundation. From my point of view, 30cm (12 inches) is not enough to support a roughly 1.8m (6 feet) high wall along with the adjacent garage and garden.
The neighbor disagrees. Therefore, my question: is there an online calculator somewhere that can determine the required foundation depth? I would rather not have the neighbor’s wall collapse on my children in a year... My construction company has also expressed concerns and does not want to carry out any further earthworks until the wall issue is resolved.
Thank you

The problem is the zoning plan, which allows significant changes to the elevation level. There is a slope, and every builder alters their driveway extensively.
Well, that doesn’t really help you now.
I have to admit that I find your posts contradictory.
Your drawing also seems to show only the intended state, not the actual condition.
Isn’t there a rule to adapt to existing structures? Not to damage someone’s foundation with your own construction? As far as I understand, he is now correctly building his foundation, but you want to excavate because you believe you have the right to do so. Or am I misunderstanding?
Best regards,
Yvonne

Hi Yvonne,
No, there is no such regulation; it wouldn’t be possible anyway on a road with a slope. The sketch indeed shows the intended final state. Currently, due to the excavation of the basement at the property boundary, there is still about 70cm (28 inches) of soil left there. Of course, that will be removed again; otherwise, I’d have a mound in front of the patio door instead of a garden.
Here is a more detailed sketch:

Is the garage already built?
In my amateur opinion, the problem lies somewhere else and is much more serious. The garage’s foundation close to the boundary should have been planned completely differently from the start. Then, the problem basically wouldn’t even exist.
