Prefabricated house or solid construction - what is your opinion?

I have to intervene here
Of course, it depends on the company, with us, they were very flexible. Exception sanitary fixtures, those are fixed.
But I was able to change almost every single socket on site again with the electrician, ...

Yes, that probably varies from company to company. You are probably right.
A positive aspect is probably also that the electrical system is easier to upgrade later, since you don't have to chisel grooves into the plaster, but work behind the panels."

I can't say anything about the feel-good climate, there is no difference for us. Psychologically we find it cool to have a prefabricated house, simply because it is something unusual. I believe we were the number one topic of conversation in the village for days, because everyone here built solidly, and even in the new development area only solid houses stand, except for 2 other prefabricated houses from my supplier. We even built in the old town center, which made it even more exotic

The thing about the wall thickness is obviously a good thing... I don't know what's normal, but our interior walls are sometimes very thin... very space-saving when it comes to pantries, etc.
By the way, they are soundproof, my father-in-law snores like a sawmill, and when visiting, he sleeps in the room next door. I have never heard him, unlike in his solid house from 2004. There I really have to make sure to sleep before him, otherwise I go crazy

Aerated concrete (Ytong) apparently has low sound insulation, but is massive...

Hello ypg,

The thing with the wall thickness is of course a good point... I don’t know what the norm is, but our interior walls are partly very thin... very space-saving when it comes to pantry rooms etc.

This is a tedious topic in the house building sector, because the home builder only accepts either/or.

Aerated concrete is - regarding sound insulation - completely uncritical at 36.5; you hear nothing from the outside world. With the thin interior walls - especially with 11.5 cm walls and also in the attic/upper floor - it looks quite different.

Here - as in almost every construction forum or also in real life discussions with interested parties - walls made of lightweight construction (like Der Da’s) are unfairly demonized. They have excellent sound insulation, are easy to assemble and - in case of later remodeling - also simple and with little mess to remove. Sometimes I’m lucky and can at least bring up the gypsum boards in the conversation

With hollow bricks, the thin walls are not quite so critical regarding sound insulation. But they also do not really reach the performance of lightweight walls.

By the way, aerated concrete tolerates the material mix better than hollow bricks. Therefore, the interior walls in the attic/upper floor could also be easily replaced by sand-lime brick (which is also often used around the stairwell), whose sound insulation is unquestionably good; even in the thin thicknesses of interior walls.

Rhenish greetings

Because of another thread, I come to an advantage of timber prefabricated construction:
For some small plots and corresponding floor area ratio, a minimal area has to be built. Due to the thinner walls in timber frame construction, you get more living space than with solid construction. This can already be 10 sqm that you gain

Insider: Don’t tell the building expert

Here are the reasons why we build solid:
- you can later more easily add something or convert
- the airtightness of wooden houses has put us off a bit, these ventilation systems seem suspicious to us
- stone houses are less often blown down by wolves or washed away by rivers

I hope modern solid houses are also tight.

Building an extension onto a prefabricated house is not a problem at all, you just take a chainsaw and go ahead Of course after consulting with the structural engineer. Likewise, you can always brick something on... the house probably wouldn't mind

On the topic of rivers and washing away: Well, wood floats, can stone do that too?

I have to agree with you about the wolves, and I’m already dreading it since the first wolves have been reintroduced in the Palatinate.... I wonder if my storm and hail insurance will cover that?

I do hope modern solid houses are also airtight.

That's true, they are. You're right. But somehow you don't need ventilation there. I forgot why.

I have to agree with you about the wolves, and I'm already dreading it since the first wolves have been released in the Palatinate.... I wonder if my storm and hail insurance will cover that?

I would ask Little Red Riding Hood about that.

That's true, they are. You're right. But somehow you don't need ventilation there. I forgot why.

The topic of ventilation also applies there. And as usual: you don't need a ventilation system if you manually ventilate every 4 hours anyway. Otherwise, many talk about 'diffusion-open construction - therefore no ventilation system required' - this applies equally in 'solid' construction as well as in 'wood' construction, but so far no one has convinced me of that. In construction with a vapor barrier (whether 'solid' or 'wood' construction), the ventilation topic tends more towards 'ventilation system required'.

What I have taken away from all the discussions: tight construction => ventilation system is at least recommended for comfort reasons. And those who cannot ventilate regularly should not even think about doing without a ventilation system.

I.
