Hello,
we would like to build a one-and-a-half-story single-family house with about 125 sqm (1,345 sq ft) plus additional development space in the attic. Without a basement but with a 9 m (30 ft) garage.
We have a plot of land in sight, which we hope to reserve by May. We have already had several appointments with construction companies, including TaC, a developer from Krefeld, and one from Sonsbeck. I feel increasingly uncertain. Both developers offer roughly the same concept, but their prices differ significantly. One says that a ventilation system is not necessary for a KfW 55 solid construction house, while the other says it is very important. I am completely confused. Intuitively, the developer from Sonsbeck was our favorite—until we saw the cost estimate.
It is just too expensive! With TaC, the costs are within our budget, but opinions about the company are mixed.
Does anyone have experience in the NRW area?
Best regards

To the moderators,
maybe you could move the controlled residential ventilation topic to a separate thread, in my opinion it’s not helpful to Judith82 here.Big "Like."
The controlled residential ventilation subdiscussion in this thread far exceeds what I would normally be accused of as "babbling." *Irony mode on* Respect! *Irony mode off*

Yes, that may be, brevity is probably not my strong suit.
However, I noticed: this is now the hundredth post (including three from me), but only five from the original poster, who mentioned the controlled residential ventilation only in passing. This particular topic now spans sixteen of the seventeen pages. I was not at all against this exchange of views, even if it is quite extensive (I would admittedly be one of the last to complain about that). Rather, I was suggesting to separate this subdiscussion.

One would think you want to gain something here through thorough quantitative work
Best regards in brief

So what? Just like their two companies, this question is very controversial.
The OP’s other question was:
That can really only be answered meaningfully in the moderated section or via private messages.

And for us, the mechanical ventilation with heat recovery made solar water heating unnecessary. So that saved about 5,000 EUR (otherwise we would have needed at least 3 collectors). How can mechanical ventilation with heat recovery reduce the need for water heating? The water you use for showering doesn’t get warmed by that system.
