Cost of house construction 2022 Single-family house turnkey

I am thinking of quite a few comrades here. The most well-known example, but I believe no longer searchable or linkable, is the user Hotzenplotz: also a Mio project, he wanted a lot of frills and many changes, everything thought through down to the smallest detail, but every corner somehow caused a problem with the general contractor (who is not suited for such things)

I was not specifically thinking of the robber - - His problem was actually first dimensionally that the general contractor indeed could build "everything" in the sense of Henry Ford (in any color, provided it is black), 08/15 gladly also with gold-framed light switches, but still 08/15; and in the second dimension, that his general contractor took the project as a guinea pig for trying out a new shell builder. Haute couture from the general contractor very likely goes spectacularly wrong, even if there should be chief physician villas with swimming pools as references.

?3: the construction service description for the "turnkey" house. [...] And that because of a house room, which a general contractor does not have in his repertoire and simply overwhelms the craftsmen.

Exactly: the construction service description is a good indicator for the presumed overwhelm of the craftsmen. The more it deviates from one’s own wishes, the more crooked it will go (see also my stone mantra). But also, which building proposals the contractor has in his program: the more he acts as a building contractor instead of a general contractor, the less practice he has with houses for clients from the higher salary brackets. Then you quickly get 70 sqm living rooms, which indeed offer significantly more area to clean - but unfortunately without a gain in spaciousness.

Therefore, it is better to build with individual contracts. Cubes and large window areas are expensive. The budget is not enough to really go towards the Bauhaus style. Just look at frameless windows… A developer or general contractor is not suitable for such a project.

yes, she also has a hillside house even though the slope here is not as steep as hers and yes, she already signed the contract in 2020. The rising costs are really extreme. We set a budget for the complete project WITHOUT furnishings at 925k. The fully developed plot with ancillary costs amounts to 280k (we can finance that with equity). Then there would be 645k left for the house + double garage. That would be about 100k more than my sister.

Build smaller. We are already paying just under 500k for a bungalow of just under 140 sqm. And that in Brandenburg and the contract was concluded in 2020 :-) We are at about €2,800 / sqm including photovoltaic system, kfw 55 (higher standard; excluding additional construction costs).

Would you be so kind as to name your [GU]? A [GU] from Berlin once transparently named to me that alone 13-15% is his margin. :)

We have set a budget for the entire project WITHOUT furnishing at 925k. The reason is that the fully developed plot with ancillary costs comes to 280k (which we can finance with equity). Then there would be 645k left for the residential house + double garage.

Sounds like you forgot the topic of taxes. : How high do you estimate the real estate transfer tax yourself? Are you aware that you also have to pay taxes on the 645k for the house, not just the land?

Sorry to have to ask again. Could someone please explain to me in detail why the cubic design in Bauhaus style is particularly costly? I would also like to build something like this again at the end of 2022/beginning of 2023 (depending on the weather). Also large, but 95% of the work done by myself. Whoever can give me tips, I am grateful for anything.
