Floor plan planning of an old building from the 1930s

Just a few points:
On the plan, the house looked interesting, but in the pictures it looks to me like a demolition candidate.
After your description, I had somehow imagined cozy farmhouse rooms, but it's so far from that.
I don't see anything worth preserving. The staircase is quite nice, but that's it. Most of the floors are also damaged and probably need to be removed for technical reasons.
The house is restorable, but as you said yourself, it’s a complete gut renovation. Almost nothing will be retained.
You have to completely strip it down, certainly reinforce it structurally, and then really start from scratch.
I see costs at a new-build level, possibly even higher. NOTHING is present and EVERYTHING must be stripped and redone.
Therefore, one can basically assume it’s uneconomical.

What I also wonder: You’re currently three people, right? What do you want to do with such a huge bunker? Even if you redesign it very generously, there’s simply a lot of space to maintain and pay for.
This applies even more to the property. As rightly says, it’s a lifelong task to maintain it.

Does the possibility that a few harmless forum members might know your address affect your interest in buying?
Somehow I have the feeling that you don’t really have a clear idea of what you want. You want to get away from the current house, that’s clear.
You say you want to be with your family now. What has actually changed from the situation a few years ago when you built in the north?
Honestly, I think you need to get a bit clearer about what you actually want.
On the one hand, a well-functioning house with fiber optic, air conditioning, and all the other comforts in which you can spend most of your time with home office, child, and gaming.
On the other hand, a huge renovation case on a huge property, the renovation of which will cost you much more nerves and time than you can bear and whose permanent maintenance will be a massive challenge.
That somehow doesn’t fit together for me. I really don’t want to offend you, but maybe you should think about it a bit more.

I understand. Since having children, we also want to live permanently near the family again. And the house has potential. Even if you have to invest a lot. Is it economical? Could be. Is it sustainable? Definitely. And with such plots, you can convert 2/3 into meadow and mow twice a year.

I'm sorry that the experience was so negative now. I understand your reaction, especially regarding the child.

To not spread this over two threads ;)

That's true! The project last discussed here has not yet been decided. I had opened a separate thread for it, in which people put in a lot of effort to google the property address and then describe it so thoroughly in the thread that now even a four-year-old could write me a postcard if we were to buy it. On the other hand, no one made an effort regarding the actual questions and the hoped-for input about the floor plan.

Then it must be a very clever four-year-old. Although at that point, the real estate agent also contributed a lot. Otherwise, in general, in times of freely available satellite photos, it is hard to keep a house private.

To come back to the floor plan. With the house, you get an old floor plan with several smaller rooms. Nothing like a modern open-plan space anymore. Whether it can be converted in that regard has to be said by a structural engineer. And whether you want that, you have to decide.
The last point is also not entirely clear to me yet. So far, you jump on all sorts of things. New build on a steep slope, core renovation of this house here. From the cute, flat 600-700sqm new build plot in Northern Germany to 2500sqm on a slope. I understand that, we back then also jumped on everything listed in Hegau that was in halfway reasonable condition. I can also completely understand that with a small child, nerves sometimes get frayed, especially if you no longer feel comfortable at home and are about to turn your life upside down completely.
But I miss a bit the classic room program from the other floor plan threads here: 1 master bedroom, 1-2 (or 3?) children's rooms, 1-2 study rooms, fitness room,... and then see if that can be sensibly implemented there. Also the question how you feel about the garden. Hobby or annoying work?
In case of doubt, I would also assume that everything that has been listed for longer than 3 weeks and not sold has a good reason for it.

To pick up the first thought again, structurally weak area, other houses will still come on the market, nothing rushed

I understand. Since the kids, we also want to permanently live closer to family again. And the house has potential. Even if you have to invest a lot. Is it economical? Could be. Is it sustainable? Definitely. And with such plots, you can also convert 2/3 into meadow and mow it twice a year.

Yes, that’s what it’s about – and that’s basically what it’s about for me too. This thread had some very specific questions, and even the title said "floor plan." Apart from very generic info, I hardly heard anything about the floor plan. And legit zero feedback on the changes we had considered. Instead, lots of unsolicited life advice, which is as disturbing as it is presumptuous. How do people come up with telling me I don’t know what I want, and backing it up with completely stupid assumptions that aren’t even true. What has changed since 5 years ago? Well, I’m married, earn about three times as much, had a son, and am no longer tied to one place because of work. But otherwise, hardly anything. Whether I’m aware of the size of the plot? Guess what, maybe I just don’t put a higher value on those weed-picked, petty bourgeois gardens like “Aunt Petunia” and would like to have 1.5 of the 2.5 square meters of land as an orchard meadow where I can gather my apples in the fall. Sometimes I wonder whether these invasive online psychiatrists actually have to compensate for something themselves somewhere between chair and keyboard.

Well, honestly, what do I have to gain here? I have been observing your story for some time now and that is the impression I have gotten. Maybe not even half of it will be accurate, but there are probably a few points that you at least take seriously enough to be offended. Anyway, I really don't want to annoy you, so I will simply leave such comments in your topics in the future and at most address the specific questions.

To get started directly: your first attempt is a start, but it is still way too detailed. I have attached a snippet that illustrates the problem. Without knowing which walls are load-bearing and which are not, planning is difficult.
