Two-story house, half-timbered, 180 sqm on a 624 sqm plot

I know your OG draft. :-D We got exactly the same from our architect,

That would give me something to think about...

... we don’t like the bathroom-dressing room-bedroom running straight through.

If that ugly walkthrough bathroom, the tiny bedroom, and the way too narrow dressing room are okay by contrast, then your comfort criteria are, to put it mildly, "very different." I’m not really in the mood to keep tinkering with this "illness," sorry.

I really can't understand the problem with the current layout either. In case of doubt, you just check whether one of the two doors can be set in the middle and then whether the furnishing is still feasible. But basically, it's only an advantage to have all three rooms connected with such short distances. By the way, did I overlook it or where is the washing machine supposed to go?

we don't like the bathroom-dressing-bedroom flowing directly into each other.

and why exactly? just saying we don't like it is not enough, a reason would be good. the layout as kaho made it is EXTREMELY practical. this way the bathroom can also be used by the kids (in case the other one is occupied, since going through the parents' dressing room shouldn't be a problem even in the later teenage years), you only have one door to the bathroom (unlike your first design, where one door also collides with the passage to the dressing room). a lockable door to the dressing room is also useful if both get up at different times, so the partner can turn on the light in the dressing room and rummage around without disturbing the other. so the morning routine is as follows: bedroom - dressing room (to get clothes or later) - bathroom - optionally back to the dressing room to get clothes - hallway. I see this as a very practical solution

I assume in the spare basement room :)

The swap of Child1 and Office somehow makes sense, our intention was to give the children the biggest rooms.

For the furnishability and thus the perceived size, nominal square meters are not the decisive parameter.
