House orientation for new construction on a north-facing plot - ideas, tips?

You are an optimist. I'll remind you again in 3 months

But that's true...... Sonnenverlauf de is the corresponding page.

I miss wall thickness (just assume 40 cm exterior walls and 20 cm interior walls, then realistic room dimensions and areas will result), as well as contour lines on the upper floor ([OG]) ([DG]). My favorite arrangement would be variant 1, but the northern bay window makes me suspicious. Primarily, I also see the bay window here only increasing the cost of the roof - how is it supposed to be useful?

I probably approached it a bit too optimistically....

First of all, thanks for the hints.

Forget about the wall thickness etc., I understand that all well.
It's only about a rough orientation.

Should the utility room really be located to the southeast, I always thought it should be cool?

The living room to the north/west and not to the south/west? Shouldn't the most sun fall into the living room and it definitely be located to the south?

I actually thought (apart from the poor drawing) the designs are not that bad, what is so bad about the floor plan?
The bay/gable is supposed to serve to have more space. Otherwise, our big wardrobe doesn't fit in the west floor plan.
You could argue about the north floor plan, but that way the bathroom wouldn't have any slants.

No, living rooms belong on the Favoriten side.

Shouldn't the most sun fall into the living room and should it definitely be facing south?

What do you gain from that? People work during the day, the dining room and kitchen take more priority, as already said.

It wasn’t about the principle for me either, but about the practical effect: walls set "too thin" distort the living area upwards.

That’s why I said the northeast side makes me suspicious. The washing machine is not demanding in terms of orientation, only the pantry is best located in the north.

The drawing is not bad at all, and the floor plans are not bad for the stage of discussion either.

The bay/gable is supposed to serve to have more space.

That’s why I asked about the benefit, or about the height lines. A cross-gable aligned with the general eave line can also provide this effect of "locally higher knee walls", combined with the wall projection adds another cost factor.
