ᐅ Prefab House vs. Solid Construction – Requesting Urgent Advice!

Hello,

we urgently need advice:

We really like the prefabricated house builder HUF. The houses and floor plans are exactly our style (timber-framed house 2000). Unfortunately, the price is quite high.

We have already bought a plot of land and now only need the right house.

Question:

HUF is like the Mercedes of prefabricated house builders. If we have a house built similarly in style by a general contractor using traditional masonry construction with some modifications, could that possibly be cheaper? Or is there no chance? Are prefabricated houses always less expensive than masonry construction?

We would be very grateful for any answers!!!

PS: The architect fees (structural engineering, planning, building permit / planning permission, etc.) are not included here, as we have already negotiated these costs with the land purchase since the plot belonged to a construction company.

...the resale value of a prefabricated house is definitely 10-15% lower than that of a comparable solid-built house.

Not necessarily for a cruck frame house,... but the lifecycle is indeed shorter.

Not so much with a Huf house,... but the lifecycle is indeed shorter.

That's right, Huf Haus certainly has a well-deserved good reputation.

Preconception About Resale Value?

I once found this point on a prefabricated house manufacturer’s website:

The resale value is lower

No one really knows for sure. If a masonry house and a timber house with the same features are built side by side and both are put up for sale after 30 years, then we will know if there is any truth to this. Our customers who want to sell their masonry house in order to build a new one with us consistently report that hardly any potential buyer asks about the construction method. Either the garden is too big, the living room too small, the street too close, the price too high, and so on. But stone or wood?

Start with whatever you prefer. I found it very interesting.

Well, that doesn’t make much sense. There are prefabricated houses that are 30 years old.
The problem, as I see it, is more that there were more possibilities to make mistakes in the wall construction or that the chipboards still contained formaldehyde.
I’m currently dealing with a renovation case, an Okal house. It smells very musty, and the exterior walls need to be completely renovated down to the structural frame. The chipboards in the ceilings will be replaced with drywall, and I hope the interior walls can stay intact... Best regards

@ parcus: It is probably well known by now that problematic substances were used in the building materials of prefabricated houses 30 years ago. That is why such houses are harder to sell.
But what about prefabricated houses built today, in 30 years’ time, which is the actual concern of emrahx99 and others? No one can predict that. Who knows whether some construction methods that are considered safe today might prove to be problematic in the future?
“Nobody knows for sure.” I find the perspective of the prefabricated house manufacturer in my quote refreshingly interesting!

For about two weeks now, there has been an EU decision that all new buildings from 2021 onwards must meet today’s passive house standard. Quote:

Europe’s builders must prepare for strict efficiency regulations. From 2021, all new buildings must be fully insulated. The EU bodies have agreed on a corresponding law. Buildings, along with transport, are among the main emitters of climate-harmful greenhouse gases. Residential houses, restaurants, and offices should be constructed in the future so that they produce as much energy as they consume. For the first time, industrialized countries are introducing ambitious regulations for buildings with the European Union. Green MEP Claude Turmes called the agreement a "breakthrough." Nowhere else in the world are there such building standards, he said after the negotiations. The negotiators from the EU Parliament, the European Commission, and the Council of Ministers in Brussels had struggled over the requirements for many months.

Following the recently reached agreement, which still requires formal approval by Parliament and the Council, new buildings will have to be equipped with energy-saving elements such as thermal insulation, solar systems, or energy-efficient lighting so that their energy consumption is only one tenth of what it used to be. The regulations apply to residential houses from December 31, 2020. New public buildings must already comply with the rules from the end of 2018.

I’m curious how builders of "masonry" construction will manage this—17.5cm (7 inches) exterior walls with 30cm (12 inches) of expanded polystyrene insulation? In 20 years, the sellers of stone houses will be complaining about the resale value of used properties.
