Dear users,
I hope you can help us.
We want to build a rural house in Bavaria.
2 full floors + attic.
11 x 11.8 m (36 x 39 feet) floor area.
38° pitched roof.
2 residential units (possibly later).
A passive house standard is aimed for, according to the energy consultant.
Since our site manager retired, we need to find another company.
All timber houses have become more expensive; offers for the shell construction are mostly between about 287,000 and 350,000.
Now we have an offer from Ytong for 150,000, but Ytong causes us some concerns regarding sound insulation (2 loud children, etc.) and the fact that moisture is only released slowly, as well as difficulties with mounting fixtures.
We have now often heard that in our case, 24 cm (9.5 inches) calcium silicate blocks plus an external thermal insulation composite system (ETICS) would be cheaper than Ytong.
Do you possibly have some experience with this?
Or also calcium silicate block square meter prices including insulation, since the facade cost is missing from the Ytong offer.
Thank you very much.

Advising against sand-lime brick for structural reasons? That is simply nonsense.
Your concerns about chasing (making grooves for cables/pipes) are also unnecessary.
You urgently need expert advice. Using sand-lime brick for interior walls due to the weight, as the living room is spanned completely.
It might be that 17cm (7 inches) is enough, but a friend who is an architect advised against it. I will rather clarify this with the construction company regarding the wall thickness.
