House construction 130 sqm turnkey

As already mentioned, we have been dealing with this for over a year now - we also know quite a few builders in our new development area, quite a few buddies/colleagues who are building, and so on...

And believe me, I’m starting to get tired of hearing: This costs so and so much, we only pay half, our house costs only €200,000 --> So much is lied about, it’s unbelievable. I also claim that many builders simply have no idea about their own construction and trust the general contractor/developer or whoever 200% blindly. Many don’t even know the word "cost transparency" and have no idea what additional costs can arise afterwards.

Because of my girlfriend, I have direct contact/insight into the plot financing etc. --> You wouldn’t believe how many builders have to refinance :D, or rather, you really don’t want to know...

Please don’t rely on such statements from colleagues or the like.

If you want to feel secure, have a certain cost transparency, and start building with a good feeling, then you need a lot of time, lots of comparisons, and so on. You have to engage intensively with the project, otherwise you’ll end up at the bank begging for another €40,000 because your money isn’t enough.

Thank you for the detailed answer. And what would you consider a realistic price for 140 sqm with a basement?

Complete, as said, without painting and roofing work 180,000 euros.

We built cheaply, I think ;)
