Floor plan of a single-family house approx. 190 sqm with basement on millimeter paper

In the upstairs floor, we followed Würfel's suggestion (unfortunately, I don't know how to tag a user??)

Very simple, just write the name with "@" in front of it:

I found Würfels' proposal better, though, with the door from the parents' bathroom to the hallway. As it is planned now, you have to take the path through the dressing room and bedroom every time. It would bother me if I could stay in bed longer than the other party.

I also like the floor plan very much, but with Würfels proposal, I would make sure not to place the water pipes on the bedroom wall if possible. Otherwise, I would have noise disturbance there if I could stay in bed longer than the children :)

Probably, and as is often the case, the straight staircase is partly responsible for such problems. In principle, I like [Bad-en-suite] or a quasi separate sleeping apartment in the house. But I don't quite like this one yet, also because in a small bedroom you look directly from the bed to the door and don't have a second door inside. The bedroom doesn't necessarily have to be large but at least nicely situated/shaped, and in my opinion, it is not so far. Directly next to the stairway and right from there into the bed.

Why don't you remove the kitchen wall?
A emergency exit should be installed in the master bathroom. The room is trapped on two sides and the way there must be planned early.

We took your advice and drew everything on millimeter paper

At least concerning me, you only half listened to our advice there: six meterthreeten, five meteroneand ninety and the like do not give the impression that the advantage of the millimeter paper, to plan with no higher accuracy than to the decimeter, has been understood. I would even recommend double decimeters (and only for small stuff like, for example, a "T" in the bathroom single decimeters at all). Moreover, millimeter paper does not make dimension chains completely obsolete – not omitting these makes it more reader-friendly for the discussants. Besides, the room sizes give me the impression that one is not stingy when it comes to generosity – almost a bit like new self-employed people whom their tax advisor advises to "incur costs."
