Raised terrace with L-stones / corner stones - How to implement the slope?

Good evening!

We also want to tackle our garden this summer, specifically our raised terrace. It is to be redone this year.

The terrace is approximately 3.5m x 6m in size and is 70cm above ground level. The border of the terrace is to be made with L-shaped stones that are 80cm high and 100cm wide. However, I keep stumbling over one issue in the planning, namely how to create a slope with L-shaped stones.

To create a slope, the side walls must be set slightly "tilted." However, this causes a larger gap at the bottom where it meets the front wall than at the top. With an 80cm height and a 2% slope, the gap at the bottom would be almost 2cm larger than at the top.

To counteract this, the front wall would also have to be set slightly tilted. Alternatively, the side wall would have to be cut accordingly. However, in any photos of raised terraces with L-shaped stones, I can see neither one nor the other.

How is this difference compensated for in practice? Or are constructions with L-shaped stones often done without a slope?

The latter would of course be the easiest. We are planning to build an aluminum roof over the entire raised terrace. Would that be sufficient as an alternative to a slope in such a case—knowing that it would not be ideal?

Over which dimension do you want to create the slope? For the 3m, I would only create it on the surface. Then the surface simply starts 6cm above the edges of the L-steine. For the 6m and with a 12 cm difference, I would stagger the L-steine. Either each one 2cm lower or in pairs and then larger steps.

The terrace is 3.5 meters deep and 6 meters wide. The slope would therefore run over the 3.5 meters.

Creating the slope only over the surface is certainly an option. Depending on the execution, they would then be, as you said, 6 cm above or below the L-edge. I don't find that visually appealing and rather see it as a tripping hazard.

But there has to be a railing in front anyway if it goes down 1m behind it. In that respect, it might also be disguised with a kind of threshold on the railing. In any case, there will then be no tripping hazard.

Do you want to keep the L-stones visible? I would (if there is enough space) fill in earth sloped on the outside and create a great rock garden or several steps made of stones with plants. That way you can also disguise the step (ground cover) and you wouldn't need a railing either (which I wouldn't install at 80 cm anyway).

I think that's a good idea . But with 80cm straight down you basically have to. Well, the question is whether anyone will come to check. But for me and my family I would have to do it out of self-interest as well, otherwise I would have to take out additional accident insurance...
