ᐅ Retaining Higher-Level Neighboring Properties: L-Shaped Retaining Walls and Tips

Hello everyone,
I need your expertise. Due to the new elevation of our new build, I have to retain neighboring properties that are higher. The required retaining height would be 1-1.5 m (3.3-5 feet).
My first choice was concrete retaining walls (L-shaped blocks), but I cannot install the footings pointing towards the neighbors, as this would significantly encroach on their land.
Do you have any ideas, tips, or alternatives for me?
Best regards

The question of whether the price is justified always depends on perspective – is it a surcharge compared to the mass-produced standard product, or does the mass-produced standard product have a particularly large discount compared to the "normal price" due to mass production? Depending on the viewpoint, either one appears overpriced or the other especially cheap. As customers, we tend to consider the lowest prices as the standard for comparison.

I suspect that the reverse construction method makes the blocks more expensive because they have to be taller since the lower part of the L is going to be built over, right? So the L has to be set deeper, meaning taller blocks...That’s probably the case, depending on what I want to cover the footings with on my side. It makes a difference whether it’s going to be paved, grass, or deeper-rooted shrubs.hampshire schrieb:

In our case, the contractor didn’t charge extra for the special models of the wall panels. However, I only had very few of the special models and quite a lot of the standard versions.
The area shown in the picture is supposed to be excavated 1 meter (3.3 feet) deeper now? I don't understand how you plan to do that. Is there a site plan from the building permit / planning permission with elevation details? You might be able to mark the problem on that. A cross-section drawing would also be helpful.
I would prefer not to publish the entire site plan here. I ask for your understanding and will also try to provide a section drawing later.
Some preliminary information:
Top edge of the finished floor level is at 25.7 meters above sea level (m asl) (84.3 feet). This will also roughly represent the height of the outdoor areas around the new house.
The area where the team is standing in the photo is at 26.2 meters above sea level (m asl) (85.9 feet).
The neighboring property is behind the deer fence, so it is at least +1.0 meter (3.3 feet) higher than the 26.2 meters above sea level (m asl) (85.9 feet). However, this is really the worst area. Generally, the height of the adjacent neighboring properties can be assumed to be around 26.5 to 26.7 meters above sea level (m asl) (87.0 to 87.9 feet).
I hope this clarifies the situation somewhat.
