Construction company wanted in the Stuttgart metropolitan area!

We created our own floor plans and then asked everyone for them to be able to compare better.

Having your own – above all: the same – scale for comparison is good. You can also include small errors and immediately test the attention of the "readers." Unfortunately, companies tend to uncritically quote a price to lay planners for their design, even if it is poor (and merely "approvable"). But floor plans alone still leave a lot of room for interpretation. In my inquiries, question 2 is the most interesting: do you alternatively offer your most similar proven construction proposal (whether it is called a "model house" is secondary).

Hauser was by far the cheapest in comparison. Which you can also notice in the execution. Thin expanded clay brick walls with ETICS

Stone on stone or as wall panels? – Expanded clay should be feasible as GEG / EH55 standard even without ETICS. Not everyone likes ETICS and personally I also don’t find it compatible with QNG.

Fermo [...] do all trades themselves [...] AWS [...] Is a pure general contractor and awards all trades.

You probably mean "a pure shell builder." Doing all trades yourself suggests a general contractor that is actually "too big" for single-family houses (and probably also a construction manager at the same time). For the client, the "employee ratio" is value-neutral and therefore not really suitable as a decision (or even just scoring) criterion. I always request the garage at least as a separately stated option if it is not architecturally integrated (to avoid disturbing comparability, as in my experience it is a purchased item). Besides, in my view it is usually not worth making a fuss about it. Its task is to be a basket for the metal pet and not to spoil the ensemble. My cars don’t wear Prada (and have to make do with the kid’s table). If I were an influencer and they contributed significantly to the household income, I would be open to discussion – but not before.

[*]Hauser was by far the cheapest in comparison. Which is also noticeable in the execution. Thin lightweight expanded clay walls with ETICS.

Thank you very much, this is a very good summary, which we would largely agree with except for the Hauser point. We decided on Hauser about 5 years ago and have never regretted it. Above all, we really cannot understand the point "Which is also noticeable in the execution". The execution was excellent except for minor details, even though, of course, we lack comparison opportunities. Yes, if you don't like ETICS, then it’s the wrong place, but personally, we were ultimately convinced by the overall concept with its good price/performance ratio :)

Hauser was almost 100k cheaper compared to the rest. And we had also inquired with Lechner, who also build with prefabricated walls. The 100k savings have to come from somewhere. We didn’t want EIFS, so Hauser was out anyway.

I ask about the garage at least if it is not architecturally integrated as a separately listed option (so as not to disturb comparability, since it is typically an additional purchase item). Moreover, from my point of view, it is usually not worth making a fuss about. Its task is to be a basket for the tin pet and not to ruin the ensemble. My cars don’t wear Prada (and have to make do with the kids' table). If I were an influencer and they contributed significantly to the household income, I would be open to discussion – but not before that.

It was of course listed separately. Priced slightly above a prefabricated garage.

Stone on stone or as wall panels? - Lightweight expanded clay should manage as GEG / EH55 without external thermal insulation composite system. Not everyone likes ETICS and I personally also find it not compatible with QNG.

The house is built with prefabricated walls made of cast lightweight expanded clay. 14cm Liapor + 19cm polystyrene. Only Lechner still offers this without ETICS and alternatively with expanded glass, which allows building somewhat thinner.

() Yes, if you don't like ETICS, this is not the place for you, but personally we were ultimately convinced by the overall concept with a good price/performance ratio :)

Hauser builds exclusively with expanded clay and ETICS? Even for the KFW55 standard?

Our ranking:

[*]Köhler
[*]AWS
[*]U-Haus
[*]Fermo
[*]Bauart
[*]Härtter
[*]Lechner Massivhaus
[*]Hauser

Maybe it helps one or the other in their decision/search.

Good luck!

Thank you very much for your interesting contribution. For what reasons does Lechner rank 7th with you?
