Detached house ~ 150 sqm for 5 people

Can we see the property with a north arrow? Maybe we will rotate the house...

Does it still make a difference if the kids have to pass by the living area to get to the kitchen when they're making noise in that very area anyway?

I don’t know what you’re talking about, but it doesn’t necessarily have to have anything to do with noise when friends meet for a beer or pizza or coffee.
But they should be able to meet, and the house should offer each resident the maximum necessary privacy with consideration for the others in order to develop personally.

And before anyone here thinks I want to impose my lifestyle on others again: yes, I grew up with an open staircase to the dining/living area. My parents built it that way and talked themselves into it over the years. Still, at some point I avoided inviting friends over. Why, one can figure out for oneself. By the way, my parents only had one child, who only ever invited one person. But it’s of course okay if you’re selfish.
You probably can’t talk yourself into the hassle with three either, at least not if you still want to enjoy some togetherness.

Yes .. I agree, by now my recommendation is rather a somewhat closed living/TV/reading room that can definitely be entered separately and a larger open space for cooking/eating=sitting=playing etc., preferably with garden proximity. I have seen it at my brother’s place with his children. They arranged to cook together .. and where was it done, where the parents could withdraw most elegantly. Not that things weren’t sometimes done with parents and even friends, but it was simply more independent. It basically starts already as a couple. One gets visitors, you want to chat, eat, drink, the other also gets visitors .. watching football or something.

That's how it is. And the more people live under one roof, the more you have to consider during construction whether it works "together." You don't have to say "we all love each other" for that – groups don't want to be in the same room with others, that applies just as much to the girls' night among wives as to the football clique of any age. The popular gallery/open space is the same: many want it. But the fact that open spaces transmit sound is not considered. With two people you can live with it; with children, you could realize your dream if you make a closed corridor on the upper floor for the sleeping area. But whoever just builds away shouldn't be surprised if there are complaints.

You were not allowed to visit my girlfriend back then. Her mother always had migraines and was lying on the sofa... that was unpleasant, so visits were forbidden because the children's room was behind the [WZ].

because the children's room was behind the living room.

Who planned that?

With the 3 children, I would completely rethink the plan again:

1. I would build somewhat larger and instead remove dormers and bay windows from the list.
2. I would completely separate the chill area and the kitchen/dining area. The chill area can be small, the play area larger.
3. I would cancel the chimney. You can see it – in Germany it hardly gets cold anymore. The new heating systems also ensure that you never feel like lighting the fireplace. Rather plan for a nice aquarium or plants. In the heat, any source of more humidity is welcome.
