ᐅ Frost-Protected Foundation for a Wall Adjacent to an Existing Neighboring Boundary Fence

Good morning everyone,
I hope the title is clear. Here is the issue: our neighbor has built an L-shaped retaining wall as a boundary, slightly set back from the property line (about 2cm (0.8 inches)).
He does not allow us to backfill against his L-shaped wall. Therefore, we are planning to build a wall along the property line as well. This wall will be approximately 70cm (28 inches) high on average, and up to 100cm (39 inches) at the highest point.
How deep should the frost-protected foundation be at this location? Should it also be 80cm (31 inches) deep, or can it be shallower because of the neighbor’s existing wall?

there is a complete lack of common sense on their part to prohibit you from piling upFrom a common-sense perspective, I would assume:Building directly on your own boundary cannot, of course, be forbidden by the neighbor, but putting any load on an existing structure on the neighbor’s property can be.
To me, having a good relationship with the neighbor is far more important than just a solid boundary wall.
I would definitely take that into account during the planning phase 🙂

I had overlooked that. Probably because I understood it differently.
If that is the case, there is clearly no valid reason for this refusal, of course.
Good evening everyone,
Thanks for the feedback and sorry for the late reply. I have been busy excavating, and after that, we spent a week on vacation. I have now dug a trench over the full 10 meters (33 feet). On average, it is about 70cm (28 inches) deep. Towards the end, however, it is only about 20cm (8 inches) deep, because, as I suspected, I am hitting the foundation base of the neighbor’s L-shaped concrete blocks (his slope follows the same gradient, and the L blocks are 1 meter (3.3 feet) long). His comment was that I should simply "chip away" the concrete and then create a new foundation myself.
I was hoping he would still be on vacation so I could just fill it with gravel that will arrive tomorrow.
You might be able to see the situation in the attached pictures.

Build the wall as high as possible. But first, he should remove his concrete wedge from your property.
