ᐅ Prefabricated House Made from Neopor – Experiences?

Hello everyone,

After careful consideration, we have decided to build a house using the "Lego" principle. Unfortunately, we have found very few suppliers online (actually only one) that also offer some level of support. It is important to us to always have a contact person available and to have someone present during the wall casting process. So far, we have only been able to find the company Argisol for this.

Do you know of any companies in the northern German region that offer this building method?

When I look at websites like VariantHaus or similar, it seems they only provide the materials, and the builder is then left completely on their own.

But what reasons could there be? I find it unlikely that homeowners building with formwork blocks are less WordPress-savvy than other builders.

And this is exactly the question. I simply don’t know. There should be more practical experience available… for timber houses, prefabricated houses, etc., there is significantly more information.

But if you know any sources, please feel free to share them with me.

If you group all these types of "wooden houses" together, yes.

I don’t really believe that any forgotten pipes would end up exposed in front of the wall afterward. After all, there is a 5 cm (2 inch) thick insulation layer inside, which can easily be channeled for such purposes—pipes, cables, etc. Then plaster is applied over it, so standard drain pipes should be able to be concealed.

For heavy items that need to be mounted on the wall, corresponding channels can be made in advance, and a wooden batten can be screwed directly to the concrete wall as a spacer, to which cabinets or similar can then be attached. This means there is no need for anchors that have to span the 5 cm (2 inch) insulation.

The filling process is also done differently. You can’t just build the walls up completely and then pour concrete in all at once; instead, you need to fill to about 1 meter (3 feet) height, let it dry, and then continue building up. This allows proper compaction down to the bottom and also prevents segregation or voids due to the concrete falling from too great a height. So, the concrete will have to be delivered multiple times, and the quantities should be adjusted accordingly.

Hi @Elina, do you have experience with this construction method?

When it comes to backfilling, different contractors recommend different approaches. Most say to backfill three layers and then proceed. However, two contractors suggest backfilling one full story at a time—that is, backfilling up to the ceiling, then installing the ceiling, and then moving to the next floor.

But there are significant differences depending on the contractor.

If their blocks differ structurally, both statements can actually be "true." What do they each say about the recommended fill height relative to the top edge of the respective "stage"?
