From which height difference L-stones / securing

Hello everyone,

We are currently planning the civil engineering work on the purchased property, and among other things, it concerns whether the terrace should be level with the house or if there should be steps down. We would like to level the entire garden and thus also make the terrace as high as possible, since we will be removing a lot of topsoil during the civil engineering work and could then distribute it. In addition, the house is relatively high, so raising the terrain makes sense if everything is on one level, meaning the floor, terrace, and garden.

However, our property will then be higher than the neighboring property, and I would like to know up to what difference "simple and inexpensive" work can be done and from when it becomes more complicated, requiring things like L-walls.

Alternatively, two levels could be made so that the terrace is still on the same level as the house (meaning the finished floor level) and then there is a drop from the terrace to the second level, which would then be at the same height as the neighboring property. In that case, topsoil would still have to be removed, but that might be cheaper than raising everything and doing a lot of work with L-walls.

A few data points for an idea of the height specifications:

Finished floor level: 62.46
Current terrain in the terrace area: 61.47
Height at the boundary to the neighbor: 62.20

Overall, this is of course much more complicated, and the civil engineer and later the landscaper still need to plan and measure, and there are more sides of the house, but I would just like a rough idea, as it is already important for the civil engineering as a rough terrace preparation whether it will be high enough to go out of the house without a step or whether it will theoretically first go significantly down. However, we want to avoid that for aesthetic, practical, and other reasons, such as that the house is quite high as you can see and there will be a lot of topsoil to theoretically bring the entire garden up to that level.

Thanks and regards!

What does the architect or developer say about that? There is also something like an allowable height compensation that must be observed

Did our Henrik skimp at the wrong end again

I am also currently planning and designing our outdoor area, I can tell you one thing, plan to intercept as little as possible if possible.

I have about 40m here that I want to level. On a corner plot. Height difference about 1.5m.

At first, I expected to use palisades, but when I think about it, the palisades alone cost 10,000 euros plus foundation. And then comes the labor, because you can forget about setting palisades yourself due to the weight.

1m granite palisades from China about 20 euros per running meter, 1/3 of that should be in the foundation.

Concrete foundation should cost around 1000 euros in materials for 40 meters.

Alternative shuttering blocks, you can set them yourself, 1 block costs about 1.5 euros.
Looks shabby and should be plastered. But the plaster can detach after years.

: What do you mean by "saving at the wrong end"? So far, no one knows our planned expenses except ourselves. We are at a stage where the heights have been determined with the architect, civil engineer, and surveyor; it is now fixed how high the house must be regarding the backwater level, etc., and thus also how high the difference is between the starting point on the terrace and the current terrain, or... the height of the neighbor's land.

I am rather early with these thoughts because you usually only think about them concretely once the house is standing, with all the heights exactly determined, etc... Nevertheless, I would like to understand, as asked, what can generally be done.

As I said, I don't understand your post at all, and you can save yourself that because it is absolutely misleading. So far, we have only bought a plot; nothing has happened except surveying work.

- unfortunately, I don't understand how your statements relate to my post; I think apples and oranges are being compared – if something has to be intercepted, then it just has to be intercepted, and there are many ways to do that...

I have shown you 2 options and what they cost, maybe you can draw conclusions from that.

What are the total costs per running meter? Then it is easier to compare, so including material and labor? So far, I assume about 80cm height difference for L-bricks. I think you only need palisades for larger height differences, but I could be wrong. Therefore, a direct cost comparison would be nice. I believe there are quite a few options to support a terrace at 80cm height...
