What is the most cost-effective type of shell construction?

Hello,

I want to start building this year. But on the internet, I can't find any website that compares the costs of different shell construction types. But that's actually something fundamental, isn't it?

Of course, I am aware that certain construction types entail higher follow-up costs (greater insulation effort, additional work for the electrician...) than others. Therefore, a general statement is probably hardly possible.

Still, I am considering having a solid prefabricated house built (walls in Liapor, poured ready). The question now is simply, by how much is this type, compared to "conventional" building stone by stone with Liapor or brick or Ytong, more expensive or cheaper? How does it compare to a prefabricated house? What is cheaper?

Maybe someone knows a website that compares these construction types against each other. Unfortunately, I haven’t found one yet.

Thanks in advance for your help.

Hello,

Nevertheless, I am considering having a solid prefabricated house built (walls made of Liapor, fully cast). The question now is simply, by how much is this type more expensive or cheaper compared to "conventional" building stone by stone with Liapor or brick or Ytong? How does it compare to a prefabricated house? What is cheaper?

You can hardly find verifiable statements on this, as it would require homeowners to have built at least twice, once with precast walls and once conventionally.

I myself have worked for several years with precast walls like Liapor®. If carefully assembled, there is nothing to speak against this construction method. The key is the composition of the material and the surface of the walls, what is the form – does it result in an approximately smooth wall or rather a coarser grain? Important, especially in this context, is the BB – are the walls handed over ready for painting – or who is responsible for closing ceiling joints, connections, control joints, as well as plastering the walls?

The timeline is comparable to a prefabricated house provider – once planning certainty is given, the walls are produced and then erected within a few days. During this time, conventional providers are already building the masonry – thus there is no significant time savings – and in interior finishing, both variants are again equally slow or fast.

If you want reasonable quality, you will reach the point that all variations of house construction are offered at the same price level. Outliers upwards and especially downwards should, in your own interest, be avoided by a wide margin.

Best regards

Hello Ralf,

..I was also thinking more of developers or architects who already have more experience with the various construction methods.

You seem/don't want to read properly ... want ...?

There is no significant price difference, nor a time advantage. If you think of developers – they have to purchase the system you favor, the architect wants to have his services paid according to HOAI (even the originator of the system wants to see his investment amortized) – all legitimate variations, each of which inherently includes a markup.

If you want to save, the only option is to lay stone by stone by stone yourself (regardless of the type). Any "intermediary" must be paid for their service, otherwise the way to the client is shorter than you and other builders might like.

Kind regards

So it also strongly depends on your location, the prices vary greatly within the country, we live at the very top of the coast.
With us, mostly H&H or Ytong aerated concrete is used because they are partly produced nearby.
Next comes Liaplan in the Brandenburg area and far behind are Schlagmann or Wienerberger.
Then the transport costs sometimes add up so much that you quickly pay twice as much for a comparable brick.

Reading and looking things up should educate

Kind regards

First you say that there is no significant difference. In the same breath, however, you recommend stone by stone because it allows savings.
Who is supposed to understand this statement?

Hello,

First you write that there is no significant difference. In the same breath, however, you advise stone by stone because this saves money. Who is supposed to understand this statement?

Quote: "If you want to save, the only option is to place stone by stone for stone (regardless of the version) yourself on top of each other." Now clearer?

Kind regards
