Fine, now you can see something.
So I'll start on the ground floor:
The pantry is hard to furnish. Try to build it sensibly with shelves.
(Especially door and window restrict this)
When you come in through the front door, you almost fall up the stairs to the upper floor. Tight but just about okay.
The direct view/connection between the hallway and dining area is disturbing, although there is actually enough wasted space above the "dining" area, which mainly serves to display symbols on the plan...
If this "Schnubsi" wasn't in the upper left corner of the kitchen, you could furnish much more freely. But maybe it is needed statically.
The guest WC with shower makes sense on the shower side because there is a guest room next door.
The toilet window directly in front of the house entrance is not really great... the ringing guest still hears rushing and gets a half-dried hand stretched out in greeting. Ahem. Just as inappropriate is a guest WC directly in front of the dining area where everyone present can listen to the end of the business.
Something structural is simply missing in between...
Maybe swap guest and WC, move the pantry into the huge pseudo-"hallway" to the left, make the guest room accessible from the "kitchen"... You are at least giving the pantry a window, which it doesn’t really need.
The path from the kitchen to the living room will always be a zig-zag run. The living room isn’t particularly huge, but should be enough for a three-person household.
Since I find two children's rooms upstairs, I doubt that’s the case...
I don’t get the staircase layout to the garage.
Overall, there are somehow so many doors around the entrance area... What is supposed to be the door in front of the foyer? A front door? Why? Is the foyer within the thermal envelope? The exterior masonry doesn’t give that impression.
Unfortunately, views and sections are missing...
What was your motivation for this entrance area?
Upstairs, the drainage of the bathroom will be a funny task. Due to lack of options, it will probably have to go through the wall in the ground-floor living room.
So it’s not only rushing from the guest WC during dinner, but also if someone above is doing their business...
Putting the bathroom on the south side is... hmm... eccentric.
Parents and dressing room on the south side and child and bathroom up north/northeast.
Anyway... but somehow different :D
Quickly about the basement:
Washing and drying is huge (!) The only remaining room "basement" can then only be used as (necessary) storage and all the other usual later uses are dropped.
(Party, sauna, extra children’s room, etc.) But well, not everyone has a cat room either :)
Oh, and 6m for a garage would be a bit short for me personally. A comfortable station wagon already approaches 4.80 and then you still have 1.20 left for a shelf or a workbench, which you often build on the end wall of the garage...
But it works, no doubt.
Best regards
