ᐅ Realistic Price for a Single-Family Home, Possibly Turnkey

Hello everyone,
Since I've been thinking about building a house for a few months now, I came across this forum. Over the past weeks, especially here in this forum, I have read up a bit on the topic, but since I was (and still am) completely “Ahnungslos” (clueless), it’s not that easy. It’s almost frustrating before you even know what all the abbreviations mean.

As I have very little knowledge about house building and there are only a few tradespeople in my family, my girlfriend and I have decided that we want to build a prefabricated house.

After several discussions, we have now received a detailed offer from a provider. Since I don’t know if I’m allowed to name the provider, I’ll leave out the name for now, although I would, of course, be interested to hear if anyone has experience with them.

Here are some key details about our planned single-family house in Bavaria:

KfW 55 standard with controlled residential ventilation (Zehnder Comfoair 350) & air-to-air heat pump (Vitocal 200-S)
Usable floor area: approx. 180m² (1,938 sq ft)
Living area: approx. 160m² (1,722 sq ft)
Roof pitch 42° / knee wall 1.10m (3.6 ft)
Braas roof tiles, Roto roof windows, Schüco windows, etc.

A turn-key house (excluding the foundation slab) would cost us about 290,000 EUR (~$),
If we subtract various DIY contributions, the price is around 250,000 EUR (~$), but material costs would then have to be added again.
Additionally, the foundation slab costs about 30,000 EUR (~$) and the carport with garage about 13,000 EUR (~$).

What do you think? Is this a reasonable price, or is it too expensive?
I would appreciate your assessment.

I fully agree with Bauexperte. The insulation craze is completely absurd. First, you build a house as airtight as possible to meet KfW requirements, and then you install all sorts of ventilation systems just to prevent the building from developing mold.

This is totally ridiculous, especially since, in my opinion, the costs involved far outweigh the financial benefits of a KfW loan including the (ridiculous) repayment bonus.

Even a standard house built to the Energy Saving Ordinance is already tighter than necessary.

I would recommend building a house according to the Energy Saving Ordinance to save a lot of money and to overlook the KfW loan, or to check with your primary bank to see if they might finance the KfW portion under the same conditions. Our bank even offered this on their own initiative, and we completely dropped the KfW stuff.

How airtight does a house actually need to be?

As an architect, you can surely tell us that.

You never stop learning.....
Since you know, I would like you to explain how you come to the conclusion that a house built to the energy saving ordinance is actually more airtight than it should be.

In my opinion, that’s it. Whether it is architecturally correct is another matter. After all, I’m not a professional.

Yes, but somehow you must have come to this conclusion. You don’t just say that without reason.

And are you sure you’re not confusing something? Maybe airtightness and thermal insulation?
