Plot is not rectangular - looking for an idea for the floor plan

Have you given the children away or why don’t they get any more rooms? Where is the storage space supposed to be with this floor plan? Cloakroom for 4 people in case the children were not given away? Regarding variant 4: you fall straight from the entrance area into the dining room. I would not like that at all. If I were forced to build like this, I would probably choose variant 1 as well. I think 2 and 3 are complete rubbish.

Both as a "passerby" and as a "highwayman" at the dining table

I don't see a dining area or dining hall (as it used to be called) here as disadvantageous or disturbing. Even at midnight, one could (provided sitting actively there with friends, whether young or old) run into each other without intruding on privacy.

If it is to be used as a guest bathroom / children's bathroom, I would always have to march through the living room.

? The living room, i.e. the snug zone, is always a corner elsewhere. You don't have to march through it.

Unfavorable from my point of view. If it is not used that way, then one can question whether a shower is needed there.

I still see it similarly.

Why wouldn't you build a bungalow with children? I see the advantage here that everything is on one level and also easier for us as we age.

because if you also build compactly upwards, you can definitely generate more living space and thus more necessary parking/storage space for the same money. There is a difference between planning an age-appropriate house for 2 and a family-friendly house for 4. Two floors are very comfortable. You don't peep around too much but have more privacy.. the children more space for personal development.

I am threefold unconvinced by all the variants: 1. not by any of them individually, 2. that there are as many as four, 3. that nevertheless none is two-storey. Which serious architect proceeds like this? – probably at most one with still very little experience.

There were several variants with very small, tube-like children's rooms. None of them appealed to me at all. Regarding this point, I found variant 3 to be the best. Then the question of the cardinal directions. Did I overlook that? If the bottom of the plan is south, then in most variants, the children's rooms are facing north.

There is a separate subforum for exactly such questions. You will get help there.

And how old are the children? If they are not very small anymore, do they maybe like to reside upstairs (so that you could make two rooms on the left and right)? Then everything else can be left on the lower floor and it is age-appropriate right away, with a more compact floor plan. You can certainly also fit a storage room in there.

Thank you for the answers,
There are no children yet, but planned, so they have not been given away.
However, the labeling of the rooms Guest/ Work = Child 1 and Child 2, in case it works out someday.

Planunten is south.

The property has not yet been purchased, the notary contract is currently being prepared.

An inquiry with the city revealed that only a bungalow may be built on this property (to maintain the uniform appearance of the neighborhood), but the roof shape (gable or flat roof) may differ.
Accordingly, storage space under the roof is being created as "basement replacement area."
The HAR in variant 4 is also not exactly small, I estimate...

The orientation of the children's rooms is due to the desire that they do not face the terrace.

An inquiry at the city has revealed that only a bungalow may be built on this property (to maintain the uniform appearance of the neighborhood), but deviations from the roof shape (gable or flat roof) are allowed.

Does this mean that the development plan has not yet come into force, and one is still subject to the integration requirement according to §34? - Because the development plan clearly states "II", and verbal side agreements are not customary in development plans. I would not consider building a bungalow without good reason if I had children.
