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.

Thank you Daany29 for the very important report!
As someone interested in Neopor, this definitely makes me uneasy, and I regret not simply accepting the fixed price offer from the builder who uses Ytong about 1.5 years ago.
I still have a few questions:
- Which seismic zone do you live in? (Apparently not zone 3, otherwise there would have been a structural check.)
- From your point of view, is it actually feasible to lay and reinforce the blocks as well as install the alignment supports all by yourself?
Best regards

I’m not sure which earthquake zone we are in, but I received a detailed structural engineering report and various reinforcement plans.
Basically, it is doable on your own. I marked out almost the entire ground floor by myself. When it came to reinforcing, we worked as a team of two. The rest was also done by two people. Ideally, three people would be best: one marks out, two cut and carry.
Look for a masonry crew on local classifieds like eBay Kleinanzeigen. They charge about €20 per hour plus VAT. They build the walls so fast, you could never set the bricks and place the temporary supports that quickly yourself. Around 14 working days at 10 hours each, and you’ll have everything ready for the roof to go on for a standard house, including the structural plan. Just under €10,000 gross. Bricks, mortar, and prefabricated concrete slabs don’t cost a fortune.

Hello Passiv.H.N.,
I had the ventilation system planned and installed all 11 decentralized fans myself. I drilled core holes, insulated plastic sleeves beforehand, and fitted them into the wall. The fans are then inserted there. The cover is mounted on the outside, the wiring is done on the inside, and the inner cover is snapped on. You can also insert a pipe through the wall, seal it, and then pour the concrete.
It’s quite a lot of work and you constantly learn along the way.
As Daany already mentioned, it requires a lot of planning and experience. My structural design was poor. Luckily, I could talk to the engineer and had hooks made from the baskets, which made things easier. In return, I had to bend all the parts myself. If you want to build with these systems and do as much as possible yourself, you should really check whether the large window works easily with the system. Everything is possible. But whether I clip in a standard 4x12mm (0.16x0.47 inch) rebar in five minutes with euromac2, or have to thread four 16mm (0.63 inch) bars in very tight spaces, taking hours, is a different story.
For me, the supports held, and I also reinforced some corners on purpose. My garage was poured in one continuous pour. The highest point is 6.4m (21 feet). Nothing blew away.
In another place, I had two breakouts because the concrete was set too thin. The experienced concrete pump operator said it was fine based on his experience. But he usually pours around the perimeter and then only 50cm (20 inches) at a time—not like euromac2, which pours 3m (10 feet) in one go.
I’m looking forward to maybe building with hotzege and euromac2 and stacking a few more blocks (if I’m allowed). That definitely goes faster and easier than hauling normal bricks around.
One thing to remember: this is house building and a lot of hard work. That’s why there are usually professionals who make masons look old with such a system and are happy in the evening not to have moved two tons of bricks. My neighbors had their shell structure up within two weeks… including the foundation slab. They still had to assemble the bricks from front and back parts. The alignment supports were fixed with wire… and they also pour up to three meters (10 feet) at a time.
That’s it for now…
Have fun with your planning!
