Bungalow floor plan, approx. 120 m²

The charm of the matter here is that you don't have to plan a lot of hallway space in the rather manageable area. In this respect, the concept is logical. On the other hand, one must accept the consequences, such as the "bathrobe recommendation." I find the floor plan practical and tidy; essentially, it can be done that way.

"You just have to accept the 'bathrobe recommendation'"

Well, the problem is exactly the lack of charm of the matter. Even if you pat yourself on the back for utilizing the square meters without a hallway - in my opinion, the living quality suffers quite a bit here. Even in apartments that are tight, you never see an exit from the kitchen / living area into the bathroom. There is a reason for that.

Full agreement, Katja. Whether one wants to succumb to the "charm" is then up to each individual to decide. It wouldn't be "mine" either, I have to admit that. That probably came out wrong now, and instead of charm I should have rather written advantage. That probably sounded more optimistic than intended...

Guys, this is a typical Danish floor plan, which is built there hundreds of thousands of times. With an open living area and rooms branching off from it, and no hallway. Whole populations live like this, also in SE or NOR. At our friends over in Lolland, you enter the house, take off your shoes in a small entrance hall, a kind of vestibule—from this a small toilet branches off—go through a door and you’re inside. All rooms now branch off from this central room, including the stairs going upstairs. The house is not new, but at least 100 years old, and yet already built like this. So, you could say, I don’t like it. But to criticize it as impossible or wrong is not acceptable. We ourselves chose to have access via a hallway, because we like it better. That also has disadvantages, by the way. Mainly space consumption. Karsten

But the charm with little hallway can also be planned differently. As already said, the neighboring house in L-shape had a sufficient vestibule, a multipurpose room in L or so, and from the dining area a small hallway led to the bedrooms. With privacy for the one who withdraws while others can receive visitors.

In this respect, the floor plan is indeed

practical and tidy,

but not really suitable for everyday family life.

Well, you can say, I don’t like it. But to criticize it as impossible or wrong is not justified.

I like it, I don’t like closed-off hallways anyway, but the houses we know from vacation work for vacation, often not for everyday life. So if you combine one with the other (you can also call it planning), then you have a great house with little hallway.
Here I simply don’t see the everyday life factor.

If I consider that my parents often had many visitors, and I as a child preferred to withdraw and was somewhat shy, I would have become a bedwetter in this house. Ultimately, I probably would have had more problems in life, even if this actually sounds silly and exaggerated here.

Unfortunately, the OP is very busy. Too busy to reflect on our answers.

Everyday life:
Mom is relaxing in the bathtub, Leo comes home after soccer with Tom and Jonas and they first go to the kitchen counter to chug a cola. And now Mom actually doesn’t want to get out of the bathroom anymore, after all, she didn’t bring any laundry with her. Pretty stupid, because she still has an appointment.

The parents get a visit in the evening from another couple and want to cook together. Leo is now 10 and very sensitive to noise. ... keeps waking up constantly, the evening is ruined.

A year ago, when he was 9, he had to go to the bathroom in the evening while the parents had a neighbor visiting, but he didn’t want to go from his room to the bathroom and then peed in a drink bottle. And why didn’t he dare? Because he had done that a week before. And then he suddenly stood in the bathroom door after his business and saw his aunt and uncle sitting there. That embarrassed him. After all, he was only wearing boxer shorts and was already at a certain age.

By the way, the woman has [übermorgen Tupperabend bei sich]. (Porcelain is too loud, plastic must be used) If the man of the house still has the stomach flu then, she will have to cancel on 8 other women. Because the man will not sneak off three times or so with a clenched butt among women drinking sparkling wine to do his business in the bathroom, which the women then have to experience noisily.

When I think about it, this corner in total with the bathroom, bedroom, and kids’ room doors in the kitchen with the counter would be a good setting for a German feature film, a dramedy one would call it, I guess, that comes out of it.
