My problem is that I am a terrible excavator operator. I wanted the trench to be 30 cm wide. Now it is about 50 cm. I could also fill the 50 cm with concrete. But I wanted to avoid that. Although it would be covered, I didn’t like the idea. The depth is already fine. I think I tend to use wider formwork blocks and then use them as a foundation for the actual formwork blocks. Or do you have concerns about that? Best regards

Oh, it's purely about the appearance for you. Then do it so that the foundation goes down to 10cm below the current ground level and then start with your wall. That way, you don't have to fill up the garden.

We talked past each other.
I only understood your first post now.
Yes, you are right.
I would then have to dig out a bit more for compaction.
But it wouldn't be that dramatic.
The garden will be newly landscaped.
It still has to be filled.
Next door, a basement is being excavated.
They will shovel the soil over.
I was concerned that water couldn't seep away at that spot.
Best regards

Frankly, I still haven't understood the actual problem. Ok, you're a bad excavator operator. But before starting the hard work with wider formwork stones, I would simply fill the 50 cm with concrete and that’s that. Using wider formwork stones won’t make it any cheaper or more stable.... You don’t need to put any rebar in when filling with concrete, except to insert some vertical rods protruding, on which you then place the formwork stones to give the whole thing even more stability.

Your gravel layer as usual, then a mortar bed on top to align the stones evenly. At the transition to the narrower stones, you also make a concave fillet out of mortar. Then you take black paste and coat everything from below up to above the ground level.

Crosswise rebar can't hurt, as another user already wrote, but vertical rebar is definitely for your own benefit. It gives the wall significantly more stability and you can pour rows one after another while still keeping them connected with the vertical rebar.

Thank you for the answers. Today I walked one street further and invited the foreman of the shell construction for coffee. There was also coffee for the workers. He found both solutions (formwork blocks or concrete) feasible. However, he would advise me to fill with concrete because of the costs. He would form the upper edge (garden outside). He will provide me with planks for formwork. If I wait another two weeks, I can also order concrete.
