Single-family house (2 floors + residential basement + developed attic) approximately 200 sqm - changes

Look closely! Then find the mistake!

? I don't see any mistake?

Is there actually a site plan anywhere? Not in post 1, anyway. Why are the 9x9 m with 42/49 cm thick walls set?

On the one hand, your window placements do not work because you need beams on the ground floor. They have to rest somewhere on the exterior wall. But you have windows everywhere there...

On the other hand, take a look here: this is arranged much more sensibly, as it doesn’t create a bottleneck in the house, nor an installation that could be disruptive in the middle.

Unfortunately, the first post can no longer be edited here. That’s a shame, otherwise I would have liked to add or change some things. I have attached the site plan several times in between. Now again as an attachment.
No one here has been able to follow the 9*9 so far. For us, they are fixed. Just like the 42.5 cm bricks. If we win the lottery, there will be the 49 cm and then of course 13 cm more.

I have no idea about that. I would leave that to the architect. But certainly, even he can overlook something at the current stage. Which beams exactly do you mean where, so I can ask? Maybe with the new changes that is no longer an issue?!

For us, that was not an option so far because we absolutely wanted a spatially separated cloakroom/vestibule. It is currently developing in such a way that it at least does not have to be “thermally separated” (so no door is needed), and I am currently also seriously considering whether it needs any separation at all or if your design would be okay for us. The most important thing was always that we don’t have to walk through the “shoe storage area.” And that seems to be ensured with you, provided the shoe cabinet is positioned.
Our architect sent the revised designs today. I rebuilt them again. Except for the “about 10-30 cm too narrow” bedroom and the entrance area (which is now open as we wanted but still very angular and small), I like it. In the last design, the roof was also too low. We now have almost 50 cm more headroom again and have shifted the 1 and 2 m lines each 40.7 cm outward. That really pays off in terms of roof area.

Edit: Explanation about the stairs:
He added one more step everywhere. So flatter. In the basement, however, he left the tread very short and added the step at the bottom. So it didn’t have to be turned at the top. But that does not comply with the safety rule, and the stride length is also too short. So actually a flat staircase for children. I don’t know if it should rather be shortened by one step again?
The other stairs are very okay, I think.

Starting floor	Height	Length	Steps	Rise	Width	Stride length rule (60/63-65\66)	Safety rule (45/46\47)	Comfort rule (12)	Angle (30°)
Basement	277.5	390	16	17.3438	26	60.6875	43.34375	8.65625	33.70595654
Ground floor	281.5	420	16	17.5938	28	63.1875	45.59375	10.40625	32.14312698
Upper floor	268.5	393.4	15	17.9	28.1	63.9	46	10.2	32.49757156

EDIT2: We still lack space for a urinal in the ground floor WC (the suggestion from ypg could help there) and space for a cupboard in the bathroom.

If you have to, swap the WC and the 50 cm cabinet. I would find it better that way. But no one can get around your self-imposed (peculiar) rules.

For the new shoe neurosis, one could possibly also place a windbreak/vestibule including a shoe cabinet as a subordinate component in front of the entrance. For that, the exact rules for "subordinate component" in your municipality are needed.
