ᐅ Plot of land in sight – which home builder is the right choice?

Hello everyone,

We have a building plot under purchase option and are now looking for a suitable provider for a prefabricated or solid house of around 160m2 (1,722 sq ft).

While choosing a car manufacturer wouldn’t be difficult for us in terms of finding an affordable brand, the market of prefabricated house providers seems confusing, and we can’t identify the distinguishing features (which provider is the Porsche, which is the Skoda, and which is the Lada among prefabricated/solid house builders?). Is anyone able to clarify this? So far, we have received price estimates above 300,000 euros (without additional building costs) from providers like Haacke or Fingerhaus (turnkey). Are these premium providers, or should we generally expect to pay such (high) sums for turnkey houses? Are there reputable providers who offer more affordable options? To continue the car comparison, we don’t need an 8-cylinder engine, but we also don’t want a “beater” that will start falling apart soon.

Thank you very much for your input,
miet-er

It depends, if you move from Görlitz to Munich it might make sense.

I highly doubt you would find any company willing to do that. The issue here is warranties, structural engineering, and so on. A different site may require different structural calculations, etc. Pipes would have to be partially disconnected, the roof removed, and so forth.

And even more... The screed has to be removed and replaced. I suspect that the tiles/bathroom won't survive the move undamaged, the waterproofing needs to be restored, and so on. In the end, you end up with a rather expensive shell construction.

Okay, moving a prefabricated house is not recommended for the average homeowner. The prefab house planner said that one of the installers had done it before; they do this every day and can of course carry it out more easily, even in reverse order.

How can I compare the heating costs of a KfW55/40 house with those of a rental apartment with a gas boiler? And: does solar thermal combined with controlled mechanical ventilation make sense, or from how many occupants would that be feasible?

What does solar thermal energy (hot water) have to do with controlled residential ventilation (air)?

According to a provider, there is a large water storage tank heated by the heat pump of the controlled residential ventilation system. I wonder if and from when the use of solar thermal energy would make additional sense.

That is probably not a controlled residential ventilation system, but an exhaust air heat pump (e.g., Nibe 750, which is discussed in other threads—try searching for it in the forum...).
In principle, solar thermal systems are not very efficient or cost-effective because you only get hot water when the demand is low. When it’s really cold, only the particularly expensive collectors, which are mounted on a house wall (due to the low angle of the sun), provide any benefit.
