No construction and performance description in GÜ for freely planned house

So I think the problem probably really lies with the Verbraucherzentrale. Understanding this document is certainly more challenging than a booklet with complete sentences. We will now look for an expert who can deal with something like this.

That is not quite correct....

Yep. Specialist lawyer! Ask the traffic lawyer about the specific operating principle of a rotary piston engine, the necessary components, and its construction-related advantages and disadvantages. He can tell you what to consider legally in your leasing or purchase contract, but nothing more. That is then very similar to a life insurance specialist lawyer.

we have probably found our construction partner and now want to have our contracts reviewed. We have received a whole bunch of papers, including a [LV]. The gentleman we spoke with told us that they do not have a construction and performance specification as one would know it from prefab house providers or similar, because we have a custom-designed house and he is the general contractor. A prefabricated construction and performance specification ("with lots of prose") would not fit with us at all.

Congratulations on the practitioner! - a performance specification not only replaces a performance description but is basically its original. That is the essential difference between GÜ and GU, that the GÜ is not the contractor like the GU, but architect and construction contract fulfiller in one person. Therefore, it is only logical that he prepares the construction description from the client’s perspective. If your reviewing organization only works with Excel w..., who only know the rubber paragraph collections fortune cookies as you get them with the sample house as a promotional pen, that unfortunately speaks against this organization. Recognizing that it is the same in yellow should be something they are able to do.

At best, a trained office clerk checks with a checklist and sample construction and performance description whether all items are included. The item "window with glazing according to the current Building Energy Act" gets a tick – even if windows with double glazing and catastrophic soundproofing, manufactured in the hinterland of Congo, are installed.

Consumer advice centers are simply allinones ;-) and in Congo, at least, they understand something about tropical-proof materials. Regarding the number of panes, I already wrote "Are three window panes better than two?".

Conclusion: I share the OP’s good feeling here and would spend time looking not for a competent bean counter but rather for a construction-accompanying expert, because that is never wrong. Whether somewhere it says "the guest WC has no hot water tap" you will be able to find out yourself even without a consumer advice center. By the way, good GÜ also have satisfied customers and accordingly rarely appear on the district court’s agenda. Construction performance descriptions from bad construction partners are full of brand logos. The Citan is, by the way, a Kangoo, so much for the topic "Mercedes ‘or comparable’" ;-)
