Floor plan of city villa - What do you think about it?

Would you find the children's bathroom solution better?

The square meter numbers for the children are not correct yet. It has only been roughly changed for now. The children's rooms would then each be about 1 sqm larger.

Here are the views

The idea with the door in the dressing room is definitely a good one. However, then I lose closet space in the dressing room. And when you walk in, you first stand among the clothes! I don’t know if I would find that so great.

For that, you could probably put an additional dresser or closet in the bedroom. I can only estimate the dimensions now. Your clothes must look terrible if you can’t stand looking at them.
At the moment, every visitor basically runs straight into the lovers’ faces when entering the bedroom. As soon as there are children, you'll have visitors every morning. It is quite "practical" in contrast if they first had to pass through an airlock. Just as a thought experiment.

One more question: why should it be so dark in the living room? Because of our planned roofing? That is planned as a glass roof.
I’ll post the views shortly.

Well, a glass roof is definitely better than a solid roof. But because of the extensions on the left and right, it remains a cave. You only have light when the sun is directly in front of the window—so at noon. Otherwise, it’s dark. Does this garage really have to be extended that far forward?

And how is the process of the children's bathroom supposed to work? I would, in your place, put the bedroom in the room labeled Kind 2, then use the dressing room as a partition to the children's area. Put Kind 2 into the currently planned bedroom and completely do without the children's bathroom.

I can't say anything about the rest, but I too have wondered whether the children's bathroom is really necessary? One might find it quite practical and nice, but it is not really necessary with two children and if it's just a hassle to fit the bathroom somewhere, just for the sake of having it, one should consider scrapping the whole thing. In my opinion, it was too narrow at first and now it's too small to enjoy being in there.
