Feedback on single-family house floor plan, 222 sqm desired

Since "modifying" or playing Tetris is now a bit of a challenge, it really needs to be asked where the price limit lies. It does make a difference whether I have 10sqm more or less of space because of it. Unfortunately, the development plan is also missing, which one must base oneself on.
A user has already pointed it out: so much was packed into the house, all those Pinterest stories and model house ideas, that it only became the way it is because of that. Overloaded.
Maybe it's time to reflect on what is necessary? Much of it is just a "nice-to-have," but one also has to submit to some things if the house is supposed to work.

It does make a difference whether I therefore have 10sqm more or less space. Unfortunately, the development plan is also missing, which one must orientate to.

Leave the price out of it for now. As long as you’re not planning a castle, I don’t think your proposal will drive the costs up so much that you have to worry about it ;) I don’t have the development plan at hand right now. As I already wrote, the building boundaries to the northwest (where the office and living room are) and northeast (house entrance side) are fully utilized. Only a few centimeters in the northeast could still be built on. But that is visible in the attached plan. Toward the southwest, we should still be able to extend the dining room by about one meter. I don’t know what you mean by "Pinterest things," but we don’t see our house as overloaded. Only the storage room upstairs we consider a luxury.

Just quickly here... but I wouldn't be satisfied with it for myself and only post it because I probably won't have time for more at the moment. The staircase wouldn't have worked.
The upper floor would have a window above the front door. Rooms 1, 4, and 5 are recessed to the southeast, so smaller than the ground floor.

Are all the (one-sided) negative comments justified and understandable?

Yes, they are all understandable. The house is a disaster, but hey, if it makes you happy (then better not ask here!).

Many thanks for your efforts!! With this plan, some problems would be solved. I also imagine the living/dining area to be very nice.
Other problems, in my opinion, arise: where would we have storage space for lawnmowers, garden tools, bicycles, children’s vehicles, strollers, etc.? Building a garden shed for this purpose would not be effective in my opinion. This would, in turn, take up valuable garden space.

It’s just a sketch. I haven’t promised you or anyone here a well-thought-out design, nor have I said that it will work. On the contrary:

You can theoretically halve the size of both the freezer and the utility room, so there would be more storage space in the garage in the sense of a small recess. For example. Apart from that, I don’t like these airlock rooms because they waste unnecessary space. For this plot/house it is not really suitable (my opinion), because you generate a lot of artificial circulation area in a long building and unnecessary doors everywhere disturb and take up space. Personally, I would connect the garage and house entrance with a covered path along the house (e.g. a cantilever from the upper floor). That’s more than enough. Then there could be a storage room with an exterior door in a space between house and garage. But actually, mowers and bicycles would be more space-savingly stored in a storage room in the boundary development behind the garage on the plot. In my opinion, a 20-meter-long building is a garden eater on this plot anyway. The entire boundary area is lost for good use, at least on the northwest side. And nicely… you can see it. Another problem is the diagonal property boundary in the northeast, because you either lose area because of it or have to build a “stepped” facade. It might be smarter to take the northeast boundary as a straight building boundary and position the house diagonally because of that. Or Maybe have the driveway from the northwest with boundary development on the west side and get a more pleasing house that way. But putting more thought into it now isn’t worth it without a development plan, site plan, and budget! Time is too precious for castles in the air. If you really want to clutter half the house with unnecessary space just to meet the floor area ratio, then buy a bigger plot.
