Floor plan, not a specific single-family house, approximately 200m² with 2 apartments

The sound problem with sliding doors is not due to the door panel. It is because with most systems, you don't get any sealing pressure of the panel against a frame. So the door panel practically floats freely in the track system and only rests on the rollers, and air (and thus also sound) can pass around it. Not to mention structure-borne sound... There are special systems for this, but they are easily four times or more expensive. I also doubt that such systems even exist for ideas like bed separation. Possibly a heavy theater curtain might even absorb more sound than a sliding door.

I have only read reports (from providers) on the Internet that today's sliding doors are not really inferior to hinged doors when it comes to sound insulation. But of course, these might also be empty promises from the providers. As mentioned, I had a look at Knauf's Pocket Kit myself.

The residential units are not enclosed because the ground floor residential unit does not include a bathroom, but this is accessible from the communal corridor. Every door from the ground floor corridor into the residential unit would then also have to be an apartment door and not a simple interior door.

YOU don’t see that. Because YOU have no idea about the subject and haven’t read up on it.

That is per se nothing bad, I have no clue about paragliding – therefore I leave it. Or if I want to do it, I rent an instructor. Translated to residential buildings / floor plans the instructor is an architect. And he conjures working floor plans for you. Because he studied that.

I do not contradict you here, although I do not understand the logic behind this definition. If the staircase were located outside the building, would the ground floor still not be allowed to be called a residential unit or be constructed that way?

Exactly for this reason, I am here to gain experience. The more that can be rectified/improved in advance, the better. And it’s not like I am directly sitting in a paraglider, but I am trying myself out in simulation.

The height of ingratitude is when you can't even quote correctly and make false accusations

Nonsense, see attachment.

I can also give you a tip. If you think you're funny, no, you are not.

I am at least humorous only as long as the helping hand is not bitten. And goodbye!

It’s just that so far no one has really made any counter-proposals. The problem seems to be that it doesn’t seem like you’re open to something completely different, and on the other hand, the floor plan as it is now is not perceived as salvageable :) It’s also a question of how much the hobbyists here enjoy planning a house that probably will never be built anyway, since you’re only collecting ideas for the future.

Roughly speaking: You are not allowed to link here, but google for example “Haas nachhaltige Anpassungsmöglichkeiten”, at the bottom there’s an example of a single-family house -> two apartments conversion that is much better thought out. Yes, the kitchen is open, yes, there is currently only one office, but overall it still seems like a much more solid basis. But that’s why the suggestion here was “back to zero, create a room program” aka “2 children’s rooms, 2 offices (there would be the question of how big they really need to be), closed kitchen, etc. etc.” or also “take a look at existing floor plans”.

I am certainly open to changes, but they should also seem reasonable to me. And if there are only comments saying that something is supposedly bad, that doesn’t really bring any potential for improvement. Everyone has their own free time, so I am thankful for every comment, but it should be constructive criticism.

Thanks for the hint and I have taken a look at the building, but there are many things I don’t like about it and, among other things, it also lacks a utility room.

I am at least always humorous only until the helping hand gets bitten. And goodbye!

- Then show me a comment from in between. It was a reply to his last comment.

- So far, I haven't really received any help from you; all comments were just "bashing" or making fun of me with others. If you like to criticize others so much, you should also be willing to accept criticism yourself.

It’s not about what criticism you bring up, but how you bring it up. And for example, you can describe something as "unsuitable/inappropriate" or as "sh...". Although I am happy about the criticisms and grateful, as I said, I have the feeling that some were only aimed at putting me down.

You are probably right there. But here, some posts are polite and courteous and bring reality closer to you, and only you are resistant to it. Then you shouldn’t be surprised if someone at some point in this thread wonders whether...

Number of people, age: 2 adults + 2 children

... you are one of the children and your parents just don’t know what you’re doing.

The greatest criticism I received concerns the partition wall in the bedroom and the "children's bathroom". For both points, I can also understand the concerns and negative aspects.

It is just the crowning point of the entire construct, which can’t be taken seriously here. It may be harsh... but if someone wants to convince me here of a sliding door installed above a double bed, then I doubt their common sense.

Exactly for this reason, I am here to gather experience. The better everything can be fixed/improved in advance the better. And it’s not as if I immediately sit in a paraglider, but I try myself at the simulation.

You don’t gain experience by reading or asking, only knowledge. Experience is the consequence of practical approach.
However, you also don’t gain knowledge when a layman tells the expert what’s what and neither listens to nor believes the expert.

If you want to paraglide, you have to deal with theory first. Only then do you go to the training field.
What you are doing here is dreaming about the sport and then telling the experienced at the field without theory why he ignores the safety regulations and wants to change them according to his whim. Just before takeoff, you then argue why your naive attitude is the better one.

And no, it is not bashing when someone directly says that something is ill-considered, doesn’t work or is even poorly executed.
