Create submission plan for a 140m² single-family house - feedback, tips?

Here is my current bedroom, I even made the bed especially

So? Do you want it like this again now?

But that is 21 cm more than 326 cm (where 326 cm is only the raw construction measurement). In addition, the room is only 336 cm deep. The door at the top of the plan will probably extend about 90 cm into the room; a 180 cm bed with frame then leaves about 50 cm of space to the wall at the bottom of the plan... that is simply not desirable.

And swapping the WC and shower should also not fit well. Then the room would probably end up windowless, or do you want to dry a window after every shower? And the WC under the stairs does not relieve the fact that you should also be able to properly come up from there. Overall, only a correct stair section helps to check what is possible where and at what height.

Honestly, yes.
Never wanted a big bedroom.

It is not about constructing a ballroom, but a functional room, and this will be neither the ground floor bathroom nor the potential ground floor bedroom.

As said, your comments should help to improve or uncover mistakes. I can still change everything or, in the end, a good planner will also have the opportunity to get the best out of it.

I hope this is not misunderstood, I am really very grateful for the time and tips everyone has given me so far, it has already helped me move forward.

I will upload an adapted plan on Saturday, by then some things should already look better.

Yes, the lower bathroom would then be without a window, but thanks to controlled residential ventilation extraction, it should still be fine.

Honestly, yes.

Fascinating.
No, seriously. 11m² for a bedroom - no one plans that. And if they do, then they are either single and want to stay that way or a dwarf.
