Comparing with the current residents, I think, misses the point a bit; after all, we want to have our dream house in the long run, and the living area is simply a little lacking at the moment. Otherwise, I could have saved myself the whole topic here and live just as it is now with the wooden ceiling and so on.
I think this is largely understood here. One fact that has become clear over the years here is that really extensive and precise descriptions and pictures are necessary to receive truly good feedback. As soon as participants have to struggle, interpret things, or miss information, the thread quickly goes quiet, and that is exactly what the creator does not want. Therefore, a thread creator basically has an obligation to provide information. In this respect, you should actually provide a maximum of input and information, rather too much than too little. By now, over 80% of the threads here quickly die out, which in my opinion is mostly due to the creator, who provides only limited information or does not always participate in the discussion promptly. You have to know the whole context, both structurally and personally, to receive interesting inspiration; otherwise, you can just see standard solutions at hardware stores or in brochures. It is important, for example, whether you are "TV junkies" (not meant negatively at all) or occasionally watch Biene Maja with the children, whether you want to plan a different, possibly new kitchen in the long term or intend to keep it as it is because you like it. Likewise, the relationship to the terrace or if a lot of daylight is especially important to me or if I have the new TV from 2025 anyway, which hardly reflects. Your initial post is thus more than scant, you should change that, because often the problem is not in the room itself, but in the imagination or perhaps lack of creativity, and that is what a forum is for. What you ultimately do is ultimately irrelevant to the people here. (Y)our dream house does not arise from simply moving a wall, but rather from a coherent overall concept that is precisely tailored to my situation. It is therefore also important to know whether the questioner can or wants to do something themselves, what budget is available, and what they want to achieve overall. To respond to your brief initial post without a clean drawing and measurements could have been answered with two brief sentences, but by now new things are still bubbling out of you, which is good, it should now only be comprehensive and transparent to really be able to help.
