Real price for single-family house, possibly turnkey

Prefabricated house providers generally offer without a base slab because this trade is not part of their services or, in other words, cannot be created in prefabricated construction. Anyone who buys a prefabricated house usually knows that.

Kind regards

I have to disagree... the base slab was included in the price of the contract from our provider from the beginning. So generally, that is not the case.

Hello Der Da,

I have to disagree... the base slab was included in the price of the contract for work from the beginning with our provider. So generally, that is not the case

Your provider also "purchases" the base slab. Only - unlike with other providers - it does not catch your or the other customers' eye directly, since from the outset you were presented with a "complete" contract for work. Normally, it runs similarly to the thread starter

Kind regards

Then the price makes sense. Your provider is a renowned and reputable manufacturer of prefabricated houses. These houses are per se more expensive than solidly built single-family houses.

Thank you very much for your assessment, Bauexperte! Have you had any personal experience with this company?

Hello,

Thank you very much for your assessment, construction expert! Have you ever dealt with this company yourself?

No, we operate a construction consultancy exclusively for solidly built single-family houses.

However, from my various visits to new development areas, I know that there is nothing to complain about regarding the quality used by your provider. I have not yet made an evaluation of their contract documents, so I cannot say anything about the contractual procedures; but that was not the question anyway.

Kind regards

Hello,

OK, do you think that with a similar house (KFW55, etc...) in solid construction we could save something? Or is it also difficult to compare again?

Yes and no, I don’t know the architecture of your house.

I am now assuming a straightforward architecture, with 180 sqm of pure living space, I come to EUR 280,000 for a KfW 70 efficiency house, upgraded to KFW 55 adds another good EUR 25,000-30,000; plus the mentioned additional construction costs etc. The "saving" would - if at all - be in the range of around EUR 10,000.

With KfW 55 efficiency houses, the prefabricated house providers simply have the edge – due to the wall structure. But there are also solid house providers who, through their wall construction – double-layered plus inner mineral wool – can keep up with the values of the prefab house providers. One of them is the one with the red tent Drive once to a new development area in your vicinity and talk to the builders there; in some new development areas more building is done on weekends than during the week – so you should always be able to find a contact person.

The question that arises for me is why it should be a KfW 55 efficiency house with solid construction? If you decide on a prefab house provider, I can understand that – you get 55 practically delivered ready. But with a solidly built house, in my opinion it is really not worth it, because at most – at least according to our experience – you save €150.00/200.00 per year. Amortization looks different ...

The houses built today – at least if they are built by a reputable provider – are already so airtight that it scares me. For example, we no longer sell any KfW 70 efficiency house without ventilation. Everything beyond that basically means nothing else than that a lot of money must be spent on more insulation/technology and again a lot of money to limit the consequences of this technology/insulation mania. Many providers have already started to reinstall ventilation flaps in the windows so that at least a little used air can escape. This is all just not normal anymore

Kind regards

The question that arises for me is, why should it be a KfW 55 efficiency house - with massive construction? If you choose an FH provider, I can understand it – you basically get 55 delivered free of charge. But with a massively built house, in my opinion, it’s really not worth it, since you save at most – at least according to our experience – €150.00 to 200.00 per year. The amortization looks different ...

I wrote KFW 55 now so that the prices might be easier to compare. It’s not a must from my side. The FH provider we mentioned offers 55 as a standard.

The houses built today – at least if they are built by a reputable provider – are already so airtight that it unsettles me. For example, we no longer sell a KfW 70 efficiency house without ventilation. Anything beyond that basically means nothing other than that a lot of money must be spent on more insulation/technology and again much money to limit the consequences of this technology/insulation craze. Many providers have already started to install ventilation flaps in the windows again, so that at least some used air can escape. That’s all no longer normal

So you are not really a big fan of these houses? Then in your opinion, is the one-time investment in insulation/technology not worth it in relation to the monthly burden? As a layman, I see both advantages and disadvantages. However, I do not know which outweighs for me. That is probably always a matter of taste and money. After all, one also wants to have some life left and not pay off their house until they are 65.
