Terrain modeling different from the building application - allowed? (NRW)

Unfortunately, he criticizes the discussion itself and ridicules the topic with exaggerated and IMHO inappropriate comparisons. The fact remains, you want to deviate from the building permit.

Then every gardening design would deviate from the permit because somewhere an edge stone ends 30cm above the previously indicated level in the building application. With all due respect, I consider it complete nonsense to construct a what-if case now. It is about a somewhat steeper executed slope, which according to the OP is continuously at least 3m away from the property boundary. It does not matter whether planting stones or similar are used; it would be new to me that planting stones along a terrace in the middle of the property require a permit.

However, I would avoid a steep embankment, either let it run out naturally, which is difficult to mow and plant, or create terraces, which can be beautifully planted and still appear unobtrusive.

Very good idea, thank you! =)
With the expiring variant, we would also have to consider that the original site in the "3 meters from the border" area is not touched, if I understood correctly.

With all due respect

No.

I consider it to be utter nonsense ...

I consider it utter nonsense to compare a raised bed, a sandbox or a 30cm edge stone with a 1.5m high embankment.

The new state building code makes it easier. Exempt from approval according to
§62
9. Embankments and excavations with a height or depth of up to 2 m and a base area of up to 30 m²

Embankment higher than 2m? No.
Embankment larger than 30m²? Not clear from the thread. If no: exempt from approval

With the expiring version, we would also have to consider that the original terrain in the "3 meters from the boundary" area is not disturbed, if I understood correctly.

Up to 1m height is unproblematic:
§6...
2. higher than 1 m above the ground surface and are suitable to be entered by people.

Fill area larger than 30m²? This is not clear from the thread. If not: approval-free

I am just doing some calculations and if we simply retreat another meter from the boundary, then we come to 30-31 sqm that are being filled. Slightly reducing the length (perhaps with a curve) and I would say the 30sqm limit can easily be kept. This way, you still have a wide terrace and if

Up to 1m height it is unproblematic:

applies, we can also let it taper off nicely without creating too sharp an edge.

Why is an addendum not an option at all? Before you restrict yourself permanently...

You don't have to submit a completely new building application, an addendum to the existing one should be possible!?
