ᐅ Prefabricated house – yes or no?

Hello everyone,

I’m new here and have quite a few questions.
I’ve already looked through many threads in this forum (maybe too many :confused 🙂.

My wife and I are considering buying a single-family house due to a growing family and because of my wife’s parents. My requirements are:
  • House of at least 120m² (1300 sq ft),
  • at least 4 rooms,
  • low energy consumption,
  • with a basement,
  • (including the plot of land???),
  • budget: 250,000–300,000

Unfortunately, there is no suitable existing property on the various real estate portals.
That’s why I came across several companies that build prefabricated houses.

My initial questions are:
  • Is this budget realistic and sufficient for building a house?
  • What is the difference between conventional houses and prefabricated houses?
  • Are prefabricated houses significantly lower in quality compared to conventional houses?

I have also read some topics concerning certain prefabricated house manufacturers like Scanhaus Marlow, Allkauf, and others. There are always both negative and positive reviews.
  • Can the negative reviews be trusted? Can the positive ones?
  • Should I be prepared to rely on luck regarding which site manager I get?
  • Are there any prefabricated house manufacturers that are completely trustworthy?
  • What should I definitely keep in mind when contacting a prefabricated house manufacturer?

Thanks in advance.

Best regards,
Keough

...(in this case with an enthalpy exchanger): You always have a comfortable humidity level of 40-50% instead of 30% or lower, as is often the case in apartments during winter.
That’s actually one of the few things I truly regret not having "chosen"... :-(

I wrote earlier that it can be an advantage in summer...

What does that have to do with the season? The thermal transmittance (U-value) is the same in every case; the house loses heat at a constant rate. Thermal transmittance and heat storage capacity are two completely different things!

Not possible to retrofit? I find 25% humidity really quite borderline...

That seems relatively normal given the current outdoor temperatures (and the corresponding humidity) and mechanical ventilation with heat recovery without an enthalpy exchanger.
I actually wanted to ask about the possibility of an upgrade, thanks for the reminder.

Why is that? For example, when I take a shower, the humidity in our home goes from about 25% to around 35%. So what humidity would still need to be aired out?

Okay, when my wife showers for about 30 minutes with what feels like 45°C (113°F) water, everything gets fogged up and water almost runs down the walls *lol*

Happens less with ventilation, but without freezing in front of the mirror :P.

But actually, we’re drifting away from the topic of timber-frame or solid construction anyway .
