How long did it take for you from the dream to buying the house?

Hello everyone,

since the majority of prefabricated house manufacturers build their houses using timber frame or post-and-beam construction for reasons of weight and due to the relatively simple manufacturing method, these houses require extremely meticulous execution and especially detailed planning and its implementation.
There are many dangers lurking here, which may only become visible after years, but then are all the more serious. (see the terraced housing development near Frankfurt a.M. presented here some time ago)

A typical builder will hardly be able to professionally assess the constructions presented to him and recognize their potential dangers.
This is because such a construction consists of a variety of different materials with different properties combined into a new whole. Naturally, this can lead to leaks and thus to permeability in the future.
The great danger of mold formation results from this!
There are therefore significantly more and bigger problems than just the attic ladder, which actually shouldn't be a problem at all.

Solid wall constructions made of masonry are inherently airtight if they are provided with at least one coat of wet plaster - usually the interior plaster.

With this contribution, I hope to have shed a little light into the darkness and thereby made the decision easier whether to choose a prefabricated house or a solid construction.

I did not want to speak badly about solid construction either. But the argument that materials are newly connected to each other in prefab house construction applies just as much to solid construction. New combinations are also repeatedly used there. I know countless buildings that were quickly insulated and are now quietly moldy.

I don't quite understand the argument about airtightness - what good is it if my wall becomes damp from the outside? All the materials are water-conductive in some form.

It goes without saying that a house must be rainproof from the outside, and otherwise you just have to pay attention to condensation formation. Mold inside can then be largely prevented by controlling humidity if water ingress from outside has been ruled out.

I find it much more important to use materials that can tolerate moisture to a certain extent without immediately starting to mold.

I think the mentioned dangers exist just as much in solid construction and cannot be assessed by the average homeowner. My coworker is currently experiencing that most companies don’t really understand what he means when he talks about thermal bridges, sealing profiles, etc.
