House construction costs, how were they for you?

Quite funny, I just checked what costs have accumulated for me.
The house is 90% finished, price lock until the end of the construction period, all construction-related services have been billed.

For a Flair 152 RE, contracted at the end of 2020, price adjustment at the end of 2021, we are at
258,945 EUR turnkey house including selection
and about 65,000 EUR ancillary construction costs (which include an elaborate deep foundation with strip footings 3m below GOK, cistern, and gravel driveway, terrace, etc.)

324,000 EUR for a turnkey 152m² house and I haven’t lifted a finger.

Now interior finishing, landscaping, carport, shed, etc. will naturally be added.
But even if I include all that, I still don’t come close to the 3,000 EUR/m², which is set here as the "bottom limit" just for the house...

Prices at Town & Country have of course risen sharply as well. But now air-to-water heat pump and underfloor heating are included. I paid almost 7,000 EUR extra for the underfloor heating... etc.

Building cheaply is possible... you just have to make compromises, especially regarding "individuality." Nationwide, you will definitely find tens of thousands of people whom you can blindfold and who would find their way around my house blindly. Precisely because they have built almost exactly the same floor plan... so what, that way I can afford it.

What didn't turn out well with your house? What would craftsmen have done better?

That went badly with your craftsmen.

When did you build? A long time ago?

(...)Electricity incorrectly labeled (e.g. also the stove connection, but not so important, the electrician doesn’t die from it, but the customer who thinks he has turned off the stove’s fuse^^), (...)

Correct. The electrician does not die because, unlike the customer, he is a qualified electrician and follows the 5 safety rules before he starts working. The customer, usually a layperson, has absolutely no business with such things.

Unfortunately, this leads to the fact that the customer, as a layperson, is to blame for his own death even if the electrician made a mistake in labeling the fuses...

BECAUSE this can never, ever be emphasized enough. BEFORE working on electrical devices, one must always and everywhere and forever comply with the 5 safety rules. AND... laypeople must always and everywhere and forever have absolutely nothing to do with electrical wiring...

None of you would tinker with gas lines. So why with electricity?

And then in the end the electrician is supposed to be to blame? You’re slowly losing it here.

How do you come to the conclusion that something didn't turn out well with us? I never wrote that... Of course, there were one or two small problems, but fortunately, everything stayed within limits. So far, we are very satisfied with our "small" house and enjoy living here every day. "What could the craftsmen have done better?" My/our handover was okay as far as I know, so I can't think of anything the craftsmen could have done better instead. Except taking more money from me. They're good at that.
