Floor plan single-family house 170 sqm gable roof - feedback welcome :)

Then the bay window is facing west, right?

Upper floor: Bathtub and bedroom could cause headaches depending on your height. Measure the headroom when you stand up. I estimate about 1.6 to 1.7 m at the bed. You will probably push it away from the wall. Check if there is still enough space then.

Ground floor: Kitchen dining area quite tight
Hallway way too big
Have you taken a closer look at the floor plan I suggested in the old thread? Apart from the kitchen not being separated, what did you not like about it?
This huge hallway comes from the stair position and the necessary access to the study.

The access is via the flagpole.
Where is the garage or carport planned?

that still had some weaknesses. In the meantime, we have decided on a construction company and have revised the floor plan.

You are on the right track, the floor plan has already been significantly improved. I assume the stairs are now meant to lead up to the attic. The skylight in the children's bathroom is drawn protruding into the storage space, the connection detail of the cross ridge could still be softened (it has a nine-and-a-half-sided spot in the underside of the roof because the ridge only penetrates behind the wall to the hallway, this should be fixed with a half teaspoon lower roof pitch of the dormer), and the toilets and bathtub are below the 2m line. These are now only minor defects, we can get this through the inspection without welding.

This is purely feedback on the floor plan, and the pictures are obviously attached...

For this, I refer to ... saved as a bookmark so I don't have to keep rewriting it. Necessary information includes the room requirement program, plot location, orientation, etc. Here, not even the most basic info, a north arrow, is included in the floor plan. Another user, 11ant ... our elephant memory ... is going to the trouble again of posting the link so at least one can have another look at the site plan. It would have been polite of the OP to include this site plan directly in this thread and to link the old thread themselves.

I see no improvement here compared to the original draft from the other thread. On the contrary. The staircase centrally located in the hallway creates nothing but narrow corridors where you constantly bump into each other.

I have to agree here unfortunately. Very clearly visible in the 3D rendering...

I have to strongly disagree: the evolution from "objectively stupid" to "I subjectively don’t like it (especially on the ground floor), but with small corrections it’s at least buildable" is not a masterpiece yet, but still a respectable metamorphosis.
