Single-family house with >180 sqm / basement / garage

When I read your explanations like this, I would be directly interested in how large the price differences still are when adjusted for size and equipment. Of course, oak-aluminum windows cost significantly more than white plastic ones! And you can easily spend 30k here in Lower Saxony for a glass-ceramic kitchen as well. But hardly anyone does that. I rather know many who use an Ikea kitchen (which afaik costs the same nationwide). For bathrooms, there is still the good standard in various gradations between the "budget version" (=DIY store own brand, mixed with discount offers?) and "it’s supposed to last a lifetime" (=Axor and Co.? depending on other requirements?). Raffstores are considered here in any version as the luxury they are. A solid (but not superbly cheap in comparison) local builder was not even in a position to offer us any after several inquiries. Because he "had to request them first."

Are good venetian blinds still that much more expensive than good roller shutters?

With us, [Raffstore] cost almost twice as much as the offered roller shutters. Mixed: all-purpose room + office [Raffstore], the rest aluminum roller blinds.

Hello again,

your price is enormously cheap....!! Have you checked what kind of heating you are getting, which blinds, electric or manual? what garage door, are spots included, how many sockets etc? Have you done the sample selection? I think your eyes will still be opened – at that price you shouldn’t expect too much.
I have already gained quite a bit of construction experience in my life. Bought 1 house and 3 different condominiums....
We now had exclusive features in our turnkey offers..! Before signing the contract I wanted to know what exclusive means – at best, when I was a student my daughter had better apartment furnishings. My daughter’s colleague also signed a turnkey offer for €850,000 – he hadn’t taken care of the sample selection beforehand and now has to add quite a lot to each trade to get reasonable equipment. I hope you don’t end up the same way – so always check beforehand which manufacturer and which quality level e.g. the windows are etc. Windows are not just windows – I can install some for €20,000 or for €50,000, it’s like that in every trade. The catch lies in the fine print.
Fingers crossed that everything goes according to your expectations. Best regards.

Already calculated and sampled dozens of times.
Our surcharge list for special requests amounts to €60,000.
Of course, I know what heating I’m getting, I chose it myself. The ventilation system also costs €13,000 for us.
But fine if you think your offer is justified, then you just have to live with it and pay the corresponding prices. I rather believe you have trouble distinguishing the trades. If you have already included kitchen and terrace in the house price...

And state aside, the differences between Bavaria and BW (Baden-Württemberg) are not that significant.

Sorry, but how naive do you take the young builders to be, that they wouldn’t be aware of quality differences in windows or fittings in general?
Apparently, you yourself have been quite naive so far.
Most builders I know don’t build for €850,000, so most probably have to settle for the standard.

For us, raffstores almost cost twice as much as the offered roller shutters. Mixed, all-room + office raffstores, the rest aluminum roller blinds.

Yes, I can confirm that, we had an extra charge of 3500 for raffstores instead of roller shutters in the offer for 7 windows.

Regarding the statement about experience – maybe he will think differently in 20 years. Unfortunately, experience usually only comes with years – for some, never. If you don’t notice yourself what went wrong – you don’t get upset afterwards either.

Maybe there is a problem in such statements?

If you don’t notice yourself what went wrong... then everything went right! Not lack of experience, but building purposefully tailored to one’s own needs. Period.
Accusing young builders here of naïveté only means that you take your demands as a reference to extrapolate what others, if they just had more life experience, would do exactly the same way.

But that is wrong.

Even young builders are perfectly aware, especially here in the forum where such things are discussed, of possible upgrades to the standard and their costs.

And whoever creates a clear specification of what is must-have and what is nice-to-have and then compares trades with a meticulous plan and shops smartly, doesn’t have to pay the prices you throw around here even with a good house, equipment clearly above main contractor standard, and controlled residential ventilation.

Such prices can of course easily be paid if you have a different specification sheet, i.e. different demands. But then it has nothing to do with functionality anymore, but mainly with optics, haptics, small details.

Whoever has those demands is free to do so, some people build exactly for that. But discussions whether you need oak-aluminum windows each with a high-class blind now miss the Pareto principle of house building. You can easily spend 30% of the price on the last 5% of the way – and your posts read exactly like that.

I find it somewhat arrogant to describe the absence of such ambitions in young builders as lack of experience. And I can’t understand the whining about the costs of such extras either. Those things are not cheap and never have been. Those who can and want to should, but how can that serve as a benchmark?

With you it probably won’t be that expensive not because you act cleverly, but because you just want exactly all the fancy gimmicks that drive the price. That is legitimate. But it has nothing to do with experience.

By the way, figures like those from Knallkörper are just the building of the house, no furniture and no garden. They then went with tough comparisons of offers approaching 1600€/sqm. Depending on how you calculate (+ kitchen + this and that, etc.), of course you end up higher too. But here it was about construction costs.
