Your opinions on the cost of building a single-family house

Yes, painters for the walls are missing... And I wouldn't find a tile for 20€ (there are some, yes, but 20€ offers potential for surcharges that need to be added. Then stainless steel rails etc. I believe the electrical comfort equipment also does not go as far as having LAN or whatever everywhere. There can also be additional toggle switches as well as outdoor lighting. The towel radiator is too narrow at 60, 190-liter water tank may be too small.... Whether the price is reasonable can be determined by comparison offers

Thanks first of all. I will address the individual points. Regarding the comparative offers, it is the case that this company commissions the individual trades. They come from the region and the construction company has had very good experiences with them. These companies have worked together very often and the question would be whether it would work as well if we chose our own tradespeople who would then participate there. Above all, we are not very familiar and would not be sure if these companies would then do the work properly. We had met with another construction company and the base price of the house was already more expensive, so we decided in favor of this one. Of course, out of curiosity, we could inquire with other companies to compare prices. I will talk to my husband.

I meant to approach other construction companies. Some will be more expensive overall, but (hopefully) will also provide more services. That needs to be compared. Because with the interior fittings you mentioned, the previous price will probably not hold.

Base price higher: well, with exactly the same service description?

You probably compared apples and oranges...

We have carefully reviewed the specification from the other provider and apart from a few minor details, they generally use inferior products and finishing materials and are still more expensive. So we have already compared apples to apples. Nevertheless, we do not know if both providers are not too expensive. It will probably be worth it to us that we have peace of mind in our choice that they do good and reliable work.

Hello everyone,

we are in the final stages before submitting our building application and wanted to ask the group again whether the costs we have are realistic. We are building in the Gießen area.
