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.

Hello Siegfried.

The prices are hard to believe. Respect. I assume you built in Germany.

My quotes from solid construction house providers for a turnkey build with 187 m² (2015 sq ft) of living space and 90 m² (970 sq ft) of non-living space (including garage) were at least €550,000 without the land. Just the interior finishing alone was quoted at €300,000.

What bothers me about the Izodom elements is that the plastic webs seem to be available only for the 25 cm (10 inches) thick blocks. The other wall thicknesses have Neopor webs, which is probably not ideal in terms of sound insulation and fixing things to the walls.

There also seems to be a universal system with removable plastic webs, which technically isn’t really needed. What did you use?

Please share some of your experiences. Looking forward to hearing from you … :-D :

  • Did you get additional quotes from other Neopor formwork block suppliers? If yes, how did their prices compare?
  • What is your impression of the quality of the blocks?
  • Did you also use Izodom for the floor slab insulation? If yes, what was your impression?
  • Which company provided the training for working with the Neopor blocks? A German company? How was that experience?
  • Who did the concrete pouring?
  • How good are the brace supports?
  • Who prepared the reinforcement plans?
  • How was the overall support from Izodom?
Thanks and best regards
Hello,

I also requested quotes from other Neopor suppliers, but no other provider offered me a complete system from the floor slab up to the roof.

The 45 cm (18 inches) blocks I used also have a plastic web.

I have a good impression of the blocks.

The floor slab is also from Izodom. It looks very good, is waterproof, and was delivered pre-cut with a placement plan. Installation took one day.

The training was provided by the German branch of Izodom Poland. Very competent and helpful.

I poured the concrete myself (after training). You just have to avoid using too large a delivery hose. It worked perfectly. After all, it’s a one-story bungalow. For two-story buildings, it might be more challenging.

The brace supports are good (if set up sufficiently).

My structural engineer naturally prepared the reinforcement plans.

The support from Izodom was excellent from the very start!

Best regards

I can hardly believe that.

Try calculating it backwards. For a 170 m² (1,830 sq ft) house, the windows would have cost around 30,000 euros. The photovoltaic system 10,000 euros. Electrical materials 7,000 euros. Additional construction costs 30,000–50,000 euros (earthworks, drainage, telephone, water, electricity). Roof 30,000–35,000 euros. Floor coverings 15,000 euros. Interior plaster plus painting 25,000–30,000 euros. Plumbing and bathrooms 25,000 euros. Interior doors 4,000 euros. Exterior plaster on top? Foundation slab 5,000 euros.
Oops – that’s already 200,000 euros gone and the land hasn’t even been purchased yet... Nor the ventilation system... And many other things not yet paid for. This is not possible with regular contractors.

Wrong calculation. For example, windows from Poland cost €6,000. Interior plaster €8,000, flooring done personally €4,000, and so on.

Just do a quick calculation. For a 170sqm (1,830 sqft) house, the windows would have cost around €30,000. The photovoltaic system €10,000. Electrical materials €7,000. Additional construction costs €30,000–50,000 (earthworks, sewage, telephone, water, electricity). Roof €30,000–35,000. Floor coverings €15,000. Interior plaster and painting €25,000–30,000. Sanitary and bathrooms €25,000. Interior doors €4,000. Exterior plaster? Foundation slab €5,000.
Oops – that’s already €200,000 gone and the land still hasn’t been purchased... nor the ventilation... and many other things are not paid for yet. This wouldn’t be possible with regular contractors.

The kit cost €35,000...

But then you shouldn’t write in your enthusiastic post that you “only” did the construction and electrical work.
You built very unconventionally using materials from Poland, then “just like that” poured concrete, installed the floors yourself, and so on.

Please include that, otherwise you are making a false statement that a house can be built that cheaply. No, YOU built it that inexpensively yourself. Not the contractors.
I can also check the prices for a house from Izodom myself. There are many forum posts about that in Polish building forums. But those guys are building everything themselves as well.
And the Polish windows were ordered by you yourself, right?

No, I picked up the windows in Poland myself.

That's what a typical builder might do. There are more and more restrictions explaining why the price is so low.
You are an exception ;-)

And that means your prices are way off and absolutely not transferable. 99.99% of all new builds are constructed in a "normal" way.
