Single-family house assessment 170m² - construction cost overview underestimated?

Yes, it sounds cheap for German Southwest. But even if they are simpler materials, our wall tiles cost 16.90. The floor tiles 23.90 per sqm. Results in the house pictures thread. Interior doors smooth pure white are the cheapest, but take a look at them, they are okay. Polish windows, don’t be scared, here in the forum 90% of all participants will have windows from Poland without knowing it. There is only one manufacturer in Poland with Drutex Gdansk big enough to produce its own profiles. All others working with Drutex use German profiles from Veka, Schüco, Rehau etc. Almost all handles also come from Roto or Winkhaus. The builder notices nothing whether his windows were made in Iserlohn or Katowice. Karsten

We have the same size, and +/- 80k more (construction start this year).

340 k€ just for the house, if you include the EL?
Although we also ordered electrical and sanitary materials ourselves and definitely saved about another 10 k€.

323 house 5 sanitary 1 SAT/network We do not have Groß EL.

5000 for sanitary?

In-house procurement of the sanitary fixtures

Still quite affordable, incl. bathroom furniture?
