Floor plan approximately 200 sqm (3 children's rooms + sleeping room)

mh, I don't know. Should one rather not do that because of sound transmission and draft from the upper floor to the ground floor or vice versa? You read a lot of pros and cons

But, assuming I would remove the laundry room, would you simply enlarge the bathroom to about 25 sqm?

No, a laundry room on the upper floor makes perfect sense. There will also be laundry lying on the floor or it won't be the tidiest room, so: don't combine it with the bathroom!

I think the bathtub drawing makes the bathroom seem somewhat smaller than it will be.

So I see it, if we leave the house as it is, I have the entrance to the house exactly in the middle. From the front door to the neighbor, I have 6.5m according to my drawing.

If I move the driveway in any direction, I can at most move the house 2.5m backward, because the house must be at least 4m away from the neighbor, which means that the length of the house times the 4m is completely useless. Furthermore, it is completely shaded by the house.

Here is the sun path still attached on June 1st of the year House from the front

the same now again viewed from the back side of the house. Garage driveway.

The bathroom should look like in the pictures. Of course, this is only a rough idea.

For preliminary planning, far too much detail.

You should simulate your sun path for the autumn, winter, and spring months ;)

Am I right that we are talking about plot 29 in development plan 56 (Wimpasing II)? - that would be a dream in terms of flatness, only half a meter lower at the north end than at the south end.

What does "Hohlraum für" mean in the bathroom?

I am not at all a fan of the idea that after separating a dressing room, only a meager bed space remains in the rest bedroom. And I agree not to go into the detailed bathroom planning at this stage; and that the driveway takes up a lot of plot space.
