Cheek stair, one side railing, other side... built with bricks?

So I think it is already well described, I can at least imagine something under it. But a floor plan would still be quite practical so that we can get a better picture. I wonder how the staircase can suddenly be open on the wall side? Does a floor already begin there or how am I supposed to imagine that?

Remember, @11ant is active in many construction forums.

What a death-defying claim, that there could be more of them!

Well, I think that's pretty well described, I can at least imagine something from it.

Me too, but this is supposed to be about the questioners' problems here, not about the speculations in our minds:

1. The questioner is probably already gone again. 2. (In case he is still reading): The other forums are really unfriendly even more direct.
