HeiniohnePlanHello experts!
We have the following problem to solve and would greatly appreciate your helpful comments on this topic:
1. Our neighbor’s house is 13cm (5 inches) higher than ours.
2. The distance between the end of our terrace and the neighbor’s house wall is 6.3m (21 feet), consisting of 4.3m (14 feet) on our garden and 2.0m (6.5 feet) on the neighbor’s garden.
3. We are wondering how to best address this height difference?
3.1 Using retaining walls (L-shaped concrete blocks) on the neighbor’s property
3.2 By “grading adjustment” as suggested by the neighbor’s landscaper
3.3 Or other options?
THANK YOU and best regards!

WilderSueden12 Mar 2023 12:18Are we really talking about 13cm (5 inches) over 6m (20 feet)? That would be 2cm (0.8 inches) per meter or a 2% slope. Your terrace should have that kind of slope. That’s why you can easily accommodate it without noticing any difference.
Thank you for your quick reply @WilderSueden!
The correct measurement is 13cm (5 inches) from floor surface to floor surface.
Since our 3.16m (10.4 feet) terrace also has an average slope of 1.5%, there is probably around a 17cm (6.7 inches) height difference over 6m (19.7 feet).
However, this 17cm (6.7 inches) goes upwards from our side, not as a slope downwards.
And that's not really ideal, is it?

The neighbor is not allowed to divert surface water onto your property.

My neighbor has big plans; he just pays and does whatever his landscape designer advises.
Tomorrow we have a joint meeting.
The slope was already there and must be maintained. It is standard in our district in Munich.
He is responsible for managing his surface water correctly.
The question is, what is the most favorable solution for me?

It doesn’t really look like there is any noticeable slope. It seems like there is gravel underneath anyway. If the soil on top isn’t compacted, I would have said everything should settle on its own.
