Floor plan design of a two-family house

The room layout exactly meets my needs and is adapted to the property conditions.

Then your needs are either to share your living area or the private rooms with the neighbors in the house through the windows. That, for example, would be a reason for me to rule out renting this apartment. But let's assume I wanted to rent the upper floor, then I either have the parking spaces and look into your living and dining room or I own the garage spaces, then I walk past your bathroom and bedroom window. And I also have your toilet in view and earshot. The balcony is too close to the street for me. I could spit from your balcony onto the terrace, but that is probably your need?! I don't like sharing the laundry room with others. I also don't have space for my two bicycles. If I had a child, the apartment would already be out of the question for that reason alone, unless a bicycle shed is still planned. A waste of the unnecessary basement space. If I were a tenant, I would need a real storage room on the level and not a pantry that I have to pass through via a bottleneck or the kitchen. As a tenant, I want to use a storage room for storing, possibly for seasonal clothing. An ironing board, vacuum cleaner, and mop have to fit in there. For two people, it is already very large; as a landlord, you have to calculate whether the apartment will generate the rent it needs, meaning the market has to spend the money for this apartment accordingly. For three people, the all-purpose room would probably be too large and the office missing. I find the size of the bathroom and children's room successful, but this failed privacy shows poor and thoughtless planning.

@K a t j a I hope you know what you shouldn't do.

As already said by others, it is completely pointless to discuss the draft if we don't even know what you want to do with it and why you need what. We also have no desire to hear after every hint or suggestion: "That won't work because of this" or "I need that there for that reason." Then we won't have made any progress even in 100 years.

That's why there is the questionnaire. If you are too lazy to fill it out, so are we.

I think you should plan the apartments for yourselves, not for some time in the future. So think about what the parents need and what you need as an apparently committed bachelor. During the time you were arguing about why you don’t want to fill out the questionnaire, you could have easily completed it... and believe me, it’s worth it. And even if it only forces you to put your wishes together. Have you talked to your parents about what they want in their apartment? In the end, I find the new floor plan definitely better than the first one. It’s going in the right direction.

I just want the link to the better floor plans.

And you think the helpful users are breaking the forum rules because of you?

My main concern is how to possibly reduce the hallway and maybe build the house a bit smaller. The target is 12x11 meters.

Floor plan design does not mean coming up with an x by y floor area measurement, trying to squeeze out the smallest possible hallway portion in the layout, and then being proud when the result without any architect’s help looks like something comparable to other online floor plans (but of course also as the winner of the "least hallway space challenge").

I think you should plan the apartments for yourselves, not for some time in the future.

I linked in my first reply to the "misguided exemplary" attempt of another questioner for good reasons, who also follows this approach of simply copying a generic optimal universal mom-and-pop design twice, once for themselves and once on the other floor for an undefined tenant. The OP here should – at least that was my attempt – recognize 1. that he is not the first with this crazy idea, 2. that this wrong path is not really promising, and 3. that it does not really matter if he or someone else still tries it. The linked example even has roughly comparable dimensions and also an unsatisfactory development and no tangible result.

So think about what the parents need and what you need as an apparently die-hard bachelor.

Even regarding a living unit within the family, privacy is just as important. And that starts with the property: what should be "foreign," what should be "own." Accordingly, access paths and exits from the house are planned. One person gets their outdoor seating area to the southeast, the other their balcony or loggia to the southwest. Just as an example. The parking spaces, whether open or garages, do not need a strict separation of privacy, as planned here.
