Floor plan of a single-family house with an optional granny flat

I don't find that so bad now.

That is not optimal

But I didn't have a better idea about it.

That's why you also let someone plan. Also with regard to the nonsensical idea of using a single-family house as a two-family house.

I don't quite understand the floor plans either. What is what? I don't like the orientation of the rooms and yes, you can tell it is neither fish nor fowl. Single-family house or apartment? Neither fits. Are you allowed to just park officially on the street?

I don’t understand the statement "don’t understand the floor plan." Is it not clear where the bathroom, staircase, bedroom, kitchen, living room are, or is the question aiming at not being able to follow the reasoning behind why a floor plan is designed that way at all?

To break it down:

Ground floor
- Entrance area with staircase
- Bathroom
- Home office or bedroom (granny flat)
- Open kitchen (with a seating window, where the seating area is on the inside instead of as a bay window to the outside) with living room

1st floor
- Entrance area
- Bathroom
- 2 children’s rooms (1 room, bottom left, with kitchen connections)
- 1 master bedroom (this room can be connected to the children’s room bottom left)

From my point of view, this is a normal house, except the staircase is right in the entrance area and not, as often, located in the middle of the single-family house?

I do not understand the statement "do not understand the floor plan."

See my note in the crossposting:

I am not quite getting the floor plans. It would be best to show them in both versions (i.e. in the usage states "Family" and "Parents / Children").

I don't understand the statement "don't understand the floor plan." Is it unclear where the bathroom, staircase, bedroom, kitchen, living room are, or is the question aimed at not being able to follow the reasoning why a floor plan is even designed that way?

For clarification:

Ground floor
- Entrance area with staircase
- Bathroom
- Home office or bedroom (granny flat)
- Open kitchen (with a seating window, where the seating area is inside instead of a bay window outward) with living room

1st floor
- Entrance area
- Bathroom
- 2 children's rooms (1 room, bottom left, with kitchen connections)
- 1 master bedroom (this room can be connected to the bottom left children's room)

From my point of view, this is a normal house, where the staircase is located right in the entrance area and not, as so often, in the middle of the single-family house?

Ok, now I know what ground floor and upper floor are and what is supposed to go into the rooms as a single-family house.

As a single-family house
I don't like separated staircases and there is probably a reason why the trend has moved away from that. A staircase at the edge results in more walking area and often a dark hallway upstairs.
I find the distribution of space very unfortunate. Children's rooms don't have to be the same size, but here the differences are already extreme and parents give themselves almost double the area of the child with the small room.
How barrier-free is the ground floor supposed to be?

As a multi-family house
What do you do if no child wants to live in your house? Once the grandchildren come, the layout no longer works either.
With renting to others, you have different requirements for heating, water, and electricity. That costs money now for maybe perhaps someday.

I don't understand the statement "don't understand the floor plan". Is it not clear where the bathroom, staircase, bedroom, kitchen, living room are, or is the question aiming at the fact that one can't follow the reasoning why a floor plan is even designed that way?

Your presentation is dreadful. The floor plans have different orientations than the plot you are showing here. Even there, one has to figure out what you mean by many lines. We are not in a riddle guessing game. You have to turn your tablet here for it to be readable to some extent. A plot planning naturally also requires recognition of access paths and streets. Then dimensions are missing, and you MUST provide parking spaces ON the plot. None of this is visible. Then you used the program from hell. That one gives you eyestrain anyway and you can't look at it for long. And when you finally figure out how the floor plan is placed on the plot (which is not easy because apparently the setback areas don't look real (you can only guess since no dimensions are used)), you just don't see a nice single-family house but a few loveless rectangles patched together like Tetris, where no space is at all well planned.

Is the design really that dreadful?

Yes.
