Decision aid for choosing the construction company

But you can have all that with a KfW 55 house too, can't you? We have a central controlled residential ventilation system and are having the pipes laid for photovoltaic - might come on the roof later if the battery storage systems are any good and no longer so expensive.

We are doing the same. If anyone is interested in the costs according to the quote (I don't know if they will change): preparation 270 euros. (System including installation would cost 7,990 euros.) As mentioned, we are only having the later system prepared.

Right, but where is the problem if I want to convey to the OP a different perspective that is definitely not wrong?

I don't see any problem with that. However, the perspective is neither right nor wrong, just different. It's legitimate and okay.

I just noticed that in some posts you speak very confidently about your "experiences," which come across as very absolute. Yet much of it is based only on theory and still needs to be proven in practical experience...

But I don't want to harp on that either, of course everyone is free to present their own perspective. Preferably, though, a bit more factual and neutral, rather than "euphoric" and absolute :)

For example, we also checked and compared dozens (;)) of providers, nationwide, regional, massive build and not massive... and we deliberately chose a nationwide provider because they gave us the best overall picture and offer :)
So far, as long as the building is not completed, I do not presume to say we have made the absolutely right decision, although many experiences from other builders give me hope ;)

By the way, no one argued about the photovoltaic system, but about the KfW classes, where the photovoltaic system sometimes plays a role ... you took that up and called it nonsense.... :)

Have a pleasant day!

Exactly for this reason, I said that I am speaking from MY experiences and for us, KfW 40 would never have made sense, nor would a nationwide provider have ever made sense. I never said that it is not legitimate to build a KfW 40 house and look around nationwide?

I just want to point out to the OP that there are other possibilities besides a nationwide operating prefabricated house :p

What is right/wrong for him personally, the OP can find out himself based on HIS OWN experiences in the conversations :)

Unfortunately, I can only present my perspective "euphorically" and "absolutely" because that’s how it is. How am I supposed to present my perspective neutrally when I have a very clear picture about it?
Ultimately, how the OP decides does not really matter to me – however, I just want to show him what possibilities exist :)

The difference between, for example, the OP and me is that the OP "still" has no idea about the whole matter – for my part, regarding the "knowledge" in this area, I am completely at peace with myself! I also think that this is very important. Only in this way can you weigh what personally suits you.

As I said, I do not want to "advertise" for anything here or anything like that, but simply present our view of things and thereby say that there is something other than "black," namely "white."

However, I think this little discussion has also contributed to the OP looking around in several areas and not getting fixated on something too early :)
That should also be the goal of such a thread on exactly this topic :)

So.. about the topic KFW40 Plus. We just want that. Out of conviction. There will certainly be enough reasons against it, but you have to set certain cornerstones and this is one of them.

You just have to ask why? Is it about conviction? Climate change? Ecology? Or rather because you think you have no additional costs?
Is it about the subsidy or simply because you can afford the current thing?

I don’t know many regional providers around Frankfurt. Streif Haus Haus, Rensch-Haus, Fingerhaus, they are kind of local here, but they are all “below” the ones mentioned, as far as I read.

Those are not regional, they just have their headquarters with you or something like that.
Regional companies are the ones in the area that you learn about from the Yellow Pages because their websites are hardly found, since the professionals build and do not deal with optimal advertising presentations. Or because you keep your eyes open when you go to the countryside.
Apparently, you only stop at those you know from advertising. Immoscout, prefabricated house providers, Das Haus, Schöner Wohnen – they do not report about construction companies that build 50 houses a year in Buxtehude or Bielefeld.

The question is from when you still consider a company local/regional.

That’s not the point. The folks here just want to open your eyes that there are other alternatives around you as well. The closer and smaller ones are better because you are not a number with them, you don’t end up in a call center hotline when you call, maybe the finishing trades come from your municipality, your district, or quite nearby so that warranty claims can also be handled quickly. The talk is real talk, you can also talk to the foreman, with the ones you named you’re in the realm of anonymity (rented construction crews or traveling core employees). The house itself is anyway produced in a hall.

Ok, but now the question: why should this company, which I have never heard of (that doesn’t have to mean anything), be better than the others?

I also found your question a bit presumptuous. A counter-question: why should the other mentioned ones be better just because they do advertising and follow a completely different market strategy?
There are also Weberhaus, Baufritz, etc. which can also have mold problems or use other construction errors. You probably don’t sign a confidentiality clause there, but through good handling you tend to keep quiet about criticizing defects on the internet.

How would you assess the issue with the wall?

Not at all. I would evaluate: solid construction or timber frame. If solid, then (if I build again) monolithic, with timber frame it would be against nature for me to have the house built in a hall. There I would see it grow like a tree in nature and would then commission a local carpentry. The specification would be Kfw_XY.

Regional here are the following providers: Rensch-Haus, Fingerhaus, Streif Haus Haus and Büdenbender. But I would definitely exclude Fingerhaus for us, we visited their show home several times and were not convinced either by the quality or the consultant. The feeling was not right there.

In my opinion, that’s the right way to make decisions when it’s not about costs or something: building feeling.

What didn’t convince us was that the air-air heat pump was recommended to us, but we would prefer air-water. Somehow that didn’t go down well, I don’t know why.

Ask yourself whether some resistance did not go down well or what?

Additionally, the consultant communicated quite openly that he has many partner companies that can also take over individual trades, e.g. photovoltaics, floors, bathrooms.

That probably only applies to shell houses... I think you are confusing something there.
On the other hand, additional tasks are gladly discussed on site – be it additional sockets, etc. if you handle that directly with the craft company, you only have 2 years warranty. To my knowledge, quite a few companies are excluded because sockets are planned a year before and installed in the production hall.
There’s no more “talk on site.”

What “drives” me most is this wall aspect. Streif Haus Haus, for example, builds with vapor barrier.

Is this topic, in your opinion, even relevant or more a matter of belief?

And regarding the structure again: Is this even relevant?

My opinion: overrated. Who cares? Or why are you building a house?

P.s. we are all no experts, but builders, users, happy ones, already moved in, convinced and also less convinced

Absolutely right - that's why one builds KfW 40 and another KfW 70. One with brick, the other with clinker. Oh, everyone has different ideas about their house. There is no right or wrong!

But ypg is correct in everything he says. First take a look at everything and deal with the topic before you get stuck on something, that is really really crucial!

I can unfortunately only present my view as "euphoric" and "absolute" because that is how it is. How am I supposed to present my view neutrally when I have such a clear picture?

No, you can’t, if you are honest. Your impressions, but not the experience with the qualifying of the house.

That is exactly why I said that I am talking about MY experiences and with us KfW 40 would never have made sense, nor would a supraregional provider have ever made sense.

You haven’t even had those experiences yet?!!! Read this sentence: That is exactly why I said that I am talking about MY experiences and with us KfW 40 would never have made sense, nor would a supraregional provider have ever made sense. This sentence implies that you have already gained experience, that you have been living in your house for one or two years... the sentence suggests that you have already built.

Abre ypg is right about everything he says.

I have always been a woman ;) ... and therefore very discerning between: it could be, that’s how I see it, my experiences are those... // It is so, it is so, it is so... ;)
