Various wall systems of houses, fastening capabilities, strength

Once again. Yes, everyone will offer you something from the usual standard home builders. But with your wishes, that is the most expensive option you can choose. And depending on the experience of the home builder, it is not the option that is regularly built and is therefore prone to errors.

It will be more individual (including any desired wall construction for your 30kg pictures) and cheaper with a house planned for the slope by an architect. Then you can gladly build with the local carpentry or similar, who will only credit you €3,000 for leaving out the heating or similar, but not the actually calculated €10,000 (including profit), and instead present a shell construction for your own work.

Aside from that, timber frame construction on a slope is also not an easy undertaking. It has many disadvantages compared to the solid construction (at least for the basement on the slope).

Thank you.

Could you briefly elaborate on the topic "has disadvantages on the slope," if you like? I am absolutely not aware why this is the case, and I would be very grateful for advice. Because currently, I assume technically: "It doesn’t matter at all, because the massive concrete basement is on the slope, and whatever is built on top of it doesn’t matter." If this is not the case, then that is a huge point that none of the locals told me, as I have certainly asked. A mason, a carpenter. A brief note on the heating: Everyone has completely credited the heating technology. Only Schwörerhaus leaves a difference for a point "extended installation method" open, but that is only about €2,500 difference to the full heat pump, which is okay for me. You always have to see it as a big whole, which then comes out in the final apple-to-apple comparison.

If that is the case, then everything is fine. I had – and therefore already earlier criticized – understood that you get from the prefab house builders a completely timber frame built house including the basement living floor. Because that would be something that could/could lead to problems (or become expensive – either during construction or renovation).

Quick note about the heating: Everyone has completely approved the heating technology.

Does that mean they disclosed their internal calculation for the heating to you and then approved it? That would be new to me.

No idea where you read that. As I said, forums are extremely interesting, they inform you about many things you actually did not ask about. But still interesting for me, since I had never seen a concept with wood studs in the basement and it broadens my horizon after all. No, no internal calculation, I’m not interested in that either. If the offer says "WP: 28,900" and this amount is then deducted in the end if I don’t want it, then that is fine by me. And all three had a WP point in the offer, with a proper calculation of the individual item.

No idea where you got that from.

From the thread. You NEVER wrote that you are getting a massive basement. Literally only that the usual providers would also deliver you a living basement. And only towards the end of the thread, that the slope is then no slope, but thanks to filling becomes a normal plot. Just read your posts on the first pages ;)

And only towards the end of the thread, that the slope then is no longer a slope, but thanks to backfilling becomes a normal property. Just read your posts on the first pages ;)

Of course I never wrote that, because I asked about interior walls, not basements. That's exactly the point: I get answers to questions I never asked. Or is that wrong?

Let's be honest. I had already written a few points on your thread but then gradually read more and more intense (in my opinion over-) reactions from you and deleted them again. Participation here is supposed to be enjoyable for people and you can gain a lot from the discussions. Nobody, including me, likes to be approached in such a way.
Where is the problem or who forbids that opinions and thoughts are also described that perhaps weren’t always requested by you down to the last detail?
At least I have no desire for such bickering and even though I am several days older and certainly don’t have fewer construction projects behind me than you do, I appreciate the knowledge here and the time given by the participants.
I have the impression that you think you already know all this (better) and therefore don’t want to hear different thoughts. Well then....
If there was another construction project, I would ask here again and would be grateful for any help and also hints alongside my questions.
I strongly doubt your assessment that as a repeat builder you could better evaluate all the mentioned things, at least I wouldn’t approach it that way myself.
