ᐅ Potential savings with a turnkey prefab house – your assessment?

Hello everyone!

Yesterday, we visited the Viebrockhaus model home park.

We looked at the "V1."

The design is simple and straightforward. But we really like the size, room layout, and construction style—it fits our needs perfectly! That’s how we want it to be, except for two small changes...

The model home was built with "extra features" and to KfW 40+ energy efficiency standard, priced at 260,000€ turnkey!

However, we do not want to build through Viebrockhaus; we prefer to manage the construction ourselves.

We also don’t want to build to the KfW 40 Plus standard, since I’ve read several times that the additional cost is often not worth it...

Additionally, we want to do some work ourselves and have several skilled tradespeople in our family who are willing to support us.

What are your thoughts? How much savings potential do you see compared to the turnkey build from Viebrockhaus?

Is a construction budget of 200,000€ realistic? We don’t want the most expensive bricks or render, nor the most expensive tiles and roof shingles. Just a nice, solid single-family home for the future.

It’s not that we can’t get financing or anything like that. We simply don’t want to take out more money than necessary.

I would really appreciate an expert assessment from you!

Just for your information: Viebrockhaus does not build prefabricated houses, nor do they use Ytong.

And yes, even low-cost house builders have a standard house like this in their portfolio.

Can you name a few providers of low-cost houses that do not use timber frame construction?

The sentence contains a contradiction: in the single-family home sector or also duplex houses, prefabricated houses in timber frame construction are still more expensive than solid construction. However, a prefab house in timber frame construction can still fall into the lower price range if the timber framing is executed cheaply and certain services are not included.

Still, I am surprised by your question, since the thread title only mentions prefabrication, and where did timber frame construction appear in the thread?

Anyway: if you take 1800-2000 per square meter (195-186 sq ft) of living space, you are well within the standard range. This applies to timber frame construction as well. Any offers below that usually come with a construction scope that is not well defined or a basic standard in finishing trades.

With solid construction, you can see it clearly at Heinz von Heiden, for example: a hip roof on a bungalow that is not walkable, rafters thinner than in more expensive houses, paint-ready includes eaves and you have to order a container yourself.

For cheap timber frame construction, I would consider Danwood at the low end. Any changes cost quite a bit more.

Otherwise: what exactly do you want to achieve? What are you looking for? I think you are confusing some terms, so it seems like we are talking past each other.

It will be Ytong. Like the prefabricated house from Viebrockhaus would be

As I already said: nonsense.

We have an architect who is first working on the building permit and so on

A building application leads to the building permit. Your architect is submitting a preliminary building inquiry.

This won’t end well, because I don’t think Viebrockhaus deals with such “problem cases” or puts heart and soul into getting such special cases approved

A builder or general contractor will build a house on your land. The land will always be _your_ problem. In construction, this is called “on the client’s side.” Additional construction costs are also _your_ responsibility.

You are well served with an architect.

Thank you for your reply.

I think we might be talking past each other a bit... To me, a prefab house is a house that I can basically choose from a catalog and customize like a car, without it being individually designed by an architect.

So I probably misunderstood the terms, sorry about that.

The house we want to build will definitely be a solid (brick-and-mortar) construction (which it probably has to be, since we have an architect...).

Our architect simply handles all the paperwork with the building authority and always has the building regulations code handy in case any issues arise... And precisely because he is an "expert" who fully commits to this, we can’t go with a company like Viebrockhaus or similar, since the building permit (or preliminary building inquiry) process is not as straightforward for us as it is when building in a new housing development.

That is called a turnkey home.

This matches my own observation, but as can be read here https://www.hausbau-forum.de/threads/wie-viel-geht-beim-hauskauf-bzw-Bau.28074/page-4, this is apparently not always the case anymore.
