Massive building vs. Prefabricated building

well, what does like "doesn't matter" mean... I would simply be interested in why some people chose a prefabricated house and others a solid house.

Ok. For us, it was the price and the good gut feeling about the company that decided in favor of the solid house. There are also quite a few people who still believe that in a prefabricated house the wall will collapse if you fall against it and therefore build solid. In my opinion, there is a lot of "matter of belief" involved. Both have advantages and disadvantages, and depending on your own priorities, one or the other "wins." Since you had already informed yourselves about the advantages and disadvantages, my suggestion came down to deciding based on the offer/company.

Our reasons for choosing timber construction (no prefabricated house):

[*]ecological, renewable building material [*]healthy building biology / excellent living climate without high technical effort such as forced ventilation etc. [*]more traceable material chain down to the details [*]local carpentry company as a construction partner who listens and thoughtfully realizes extraordinary ideas instead of advising against them

Hello,
just go to a model home center for prefabricated houses. Do you have children?
Then let them jump around upstairs. When I wanted to build my house, I did the same and knocked on the wall from the outside. When the sales consultant came, the decision was made for us.
Best regards

: Noise protection is a matter of execution and can be achieved with both building materials or go wrong.
: Take a look at a carpentry company from the "Einer Alles Sauber" network. There you will notice differences compared to the prefabricated house manufacturers in the model house parks.

You are right. It’s all a matter of price. Nevertheless, the soundproofing of a solid house with concrete ceilings is unbeatable.

I have read that more often. The reason is: stones store heat longer.

That seems to me to be an explanation from real physicists

If that is true, why do many prefabricated house companies (by that I usually mean timber frame) have "standard" KfW 40? Try to achieve that with a solid construction. It is possible, but much more complex.
However, if KfW 40 or 40+ is not the goal, it can also be well achieved with solid construction.
