Floor plan of a single-family house 240 m² with a partially built-over garage

I know the "if I don't like the answers in one forum, then I simply go to another forum" all too well – I just notice it more with gardening topics. And even there, one wonders why they didn't just follow the initial answers that later proved to be 100% accurate.

And even there, one wonders why the initial responses, which later proved to be 100% accurate, were not taken to heart right away.

Who would please adopt any first suggestions from any writers from the big, wide internet for themselves if they obviously do not appeal to them???
hopefully no one

that is already a stalker-like boundary crossing.

Now let's keep things in perspective. My - apparently not perfect - 11ant memory is far surpassed by the relentless internet and its reverse image search. Possibly Yvonne wouldn’t have searched any further if the OP had not denied his previous publication.

However, I distance myself from the fact that the username is included here. That was unnecessary and leads to nothing here as well.

In the absence of a simple permission to link, the participants should be given a fair chance to still find their way to quasi-crossposting. Because considering the discussion at that time, it already seems borderline to discuss the project here now as "new" :-( But more than my annoyance about it, it rather makes me sad when a learning effect is, to put it kindly, "meager". Whether in the thread back then or here, some effort was indeed made to create value with the answers.

Who in their right mind would adopt any initial suggestions from random writers on the vast, wide internet if they clearly don’t appeal to them??? Hopefully no one

Of course, you can see it that way. Instead of the hoped-for confirmation, annoying follow-up questions, references to larger contexts, concrete tips – simply the opposite of confirmation – appear. The worst is, of course, when all those annoying responses later turn out to be correct and you then have to jump back and forth wildly between forums. In the case of the garden inquiries, it got really complicated, because managing the many sock-puppet accounts consumed more work than following the initial advice would have cost.

In this case, I find the reference to already asked questions and especially to the answers only sensible – because I do want to help here, but if I get it in writing that all my time in this case is wasted, then I’d rather invest it in other questions. I believe in the good in people and/or homebuilders, and maybe there is someone whose time I invest well.

A handful in total or between "medium-old" and "opening post"?

The latter.

Simply set the data protection in the account.

I have (and had) "Status," "Data," and "Activity" open to everyone.

The OP is the master of his own fortune here – when you ask him whether it has been discussed before, possibly to point out the missing learning curve, and he "knows nothing" about it, then there is really no learning curve visible.

The question was only whether the other draft has been discussed here before. I did not deny its existence. And regarding the learning curve: The speed of learning naturally depends on the time invested – and can be limited to what you call "tinkering."

The "if I don't like the answers in one forum, then I'll just go to another forum" I know only too well – it strikes me especially in gardening topics. And even there you wonder why you didn't just follow the initial answers that later proved 100% accurate.

The main recommendation was, of course, to not design any floor plan oneself. I obviously did not follow this advice, but concrete hints I did: The living room now indeed has more light than in the earlier draft, and the guest room has direct access. The upper floor now has nothing to do with the previous version, so "new flaws" are naturally not surprising.

Possibly Yvonne wouldn't have searched further if the OP had not denied his previous publication.

Due to the lack of a simple linking permission, the fellow discussants should have a fair chance to find the quasi-crossposting nonetheless. Because given the discussion back then, it seems borderline to now discuss the project here as "new" :-(

Other forums were not mentioned at all, so I denied nothing in this regard either. It is obvious that some also read elsewhere, and thus through research the memory became clear. But I also did not want to present old drafts for discussion. And switching the forum half a year later seemed reasonable given the fundamental opposition to personal planning – but apparently that exists everywhere. There is certainly no talk of "jumping back and forth" (HeimatBauer).

in view of the fundamental opposition to one’s own planning – but that apparently exists everywhere.

But that doesn’t come out of nowhere! Or do you also work as a doctor because you watched Emergency Room and Grey’s Anatomy once?
