On which of these floor plans can we continue to build?

Small children's rooms, with a staircase in the living area in one of them.

Huh? I would know that for sure!
I'm out—Merry Christmas!

The Pareto principle, as I know it, refers to 80/20. This system may work in many situations, but unfortunately not everywhere.

It is not a system, but a phenomenon; it does not work, rather the observation formulated in it is correct. I know that it is not clear to you, that's why I recommended it to you.

But here there are people who are the same in both forums and who do not let the past be the past

Your learning curve will not really become shorter if someone mercifully strikes the oldest hundred non-development steps from the list in spirit.
In several hundred posts you have moved forward three and a half steps: you two and a half (increase house depth, teleport annex opposite the garage, think benevolently about side windows) and one your wife (no longer refuse the longitudinal format).
You don't toast to such "much" progress yet with a magnum bottle; you will have to share a piccolo :-(

Huh? I would know that!

What exactly? Unfortunately, the staircase was not separate in this one. The children's rooms were not even 13 m² in size, one was 12.3 m² and the other 11-12 m². Sure, you could extend the 12-meter deep house further, but maybe we want to stay at the 90 m² area, whether 10x9 or 8x11.25 or 7x12. If the children's rooms are supposed to be about 14-15 m², then with a house width of 8 meters they have to be about 4 meters deep. Then it gets interesting how to distribute the other rooms. I have the impression that the room layout with such a floor plan somehow doesn't really get easier.

Phew, it took me three days to read through this because it is really very interesting. Great suggestions from the forum, which address and solve the obvious problems.

I can well imagine that you are someone who cannot make decisions. Or who has to weigh everything up and waits too long until they get nothing at all.

I can definitely make decisions. I just think that if one is talking about such a big number, then the floor plan should also be right.

The Pareto principle, as I know it, speaks of 80/20.
This system may work in many situations, but unfortunately not everywhere.

The difficulty of the OP is perfectly summarized by this. He can indeed make decisions, but only when the framework conditions are set/given. At work, the customers/bosses do this. In private, these are missing, the OP is responsible for the result himself and cannot weigh and prioritize his requirements. Therefore, every inspiration/improvement suggestion leads to reconsidering the whole thing.

My suggestion to the OP: move away from the graphical towards an Excel table. Write down all wishes without reference to any floor plan. Here, the saying "a picture says more than a thousand words" is nonsense. Then rank them according to importance and without "equally important," so create a ranking. This is then also the basis for the poor (sorry, I can't help myself) architect and not some self-drawn floor plan.

My suggestion to the OP: move away from graphics towards an Excel spreadsheet.

I had already advised him in that direction ( ) - so far he has only "understood" that I don't find his pictures pretty enough ...

... "understood" is all he has done so far, I found his pictures not pretty enough ...

I saw that and wanted to express it more clearly including follow-up steps. Let's see how it is received.

We also initially only used pictures as examples. However, the actual wish becomes clear only when what is seen is discussed/described and evaluated.
Which detail makes one corner better than the other? How do I currently use stairs and what do I like or not? Why exactly do we need a pantry? etc.
Only after that did we come across solutions that met the needs. We still wonder about the first floor plan, how we could have liked it.
