Hello everyone,
My wife and I are just starting to take the first steps toward building a house. We have purchased the plot of land and roughly set the budget. Initial discussions with architects have also taken place.
As a layperson, I obviously can’t take on the planner’s job and have to trust, to some extent, that I am being properly advised. But I would like to understand and consider as much as possible myself.
What I’m currently wondering: Why are houses still being built conventionally "brick by brick" when you can have prefabricated concrete elements delivered and assembled in a few days? The only concrete disadvantage I’ve found so far is the increased planning effort, since these components leave little room for modifications afterward (openings, wiring, etc.). In contrast, the advantages like saving time and probably higher quality due to standardized workflows seem to clearly outweigh this.
Still, these prefabricated elements (for custom-designed houses) remain a niche. Why is that?
Thank you very much!

So, is it generally cheaper to do formwork, concrete pouring, and masonry on site over several weeks? Surprising.Few still do traditional formwork nowadays, as most ceilings are made from precast concrete slabs.Yes, overall it is more cost-effective ... and to be honest, who wants to live permanently inside concrete walls, aside from the necessary Hilti fittings? Lightweight expanded clay aggregate blocks are unfortunately similarly expensive.
If you are interested in this system, there is a supplier who constructs polystyrene facades/partition walls and then fills them with concrete on site.
Best regards, Bauexperte
