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.

- Plus-energy house thanks to insulation values and photovoltaics
- Excess electricity is fed into the grid (power cloud contracts with energy supplier) to balance energy use during winter
- Air-to-air heat pump outside with corresponding unit inside the house
- Hot water via instant water heater
- Underfloor heating (only in the bathroom) via electric heating mats (because conventional water-based underfloor heating is too slow to have an effect in a house like this)
- For quick heating of a room if needed, electric radiators (infrared)
- Ventilation system is of course included
- That is, everything is powered by electricity. No ground-source heat pump or similar systems. No hot water storage tank, …
Hello. I have only been reading so far, but now that I see this concept, I have to register and share my thoughts.
I think the concept is great!
I also want to build something along similar lines, using insulated concrete form blocks. It will be an urban villa.
My concept would differ as follows:
Paradigma CPC collectors, 4 units, with a 1000-liter (264-gallon) buffer tank for hot water, solar thermal plus pool heating in summer, and heating support in winter.
Water-based underfloor heating in the bathrooms and my wife’s office.
Water-based fireplace in the living room.
Single split inverter systems (3 units) with A+++ rating, able to heat down to minus 25°C (-13°F) in the bedroom, living area downstairs, and office. In winter you can add heating as needed, and in summer use for cooling.
Otherwise, similar to your setup. I need to look into the cloud contracts because I originally planned to install a wind turbine plus solar panels on the roof and also use a battery storage system.
I also install instant water heaters for the case when the sun doesn’t shine and there is no wind for weeks in winter.
And the controlled residential ventilation will have a ground source pre-heater/cooler.
And I have to say—I think the system is top quality. I see no disadvantages. Those unfamiliar insist on pushing old-fashioned solutions on me. They pour 3 to 5-meter (10 to 16 feet) walls in one go, so there are no aggregate nests, and even if you have 3 or 4 aggregate nests over 48 meters (157 feet) of exterior wall—what’s the problem? There is a special concrete for this purpose that prevents such issues; it’s finer and self-compacting. My brother-in-law owns a construction company and is a concrete specialist. We can handle it. He once poured 8-meter (26 feet) walls in one go (exposed concrete) at the University of Kassel with no aggregate nests...
Have you heard about pouring walls and ceilings in one go? Like with Styro Stone in Shanghai, I think? I found that very interesting.
One more thing I noticed. Heating engineers and manufacturers always try to push the most expensive systems. How is a hydrogen heating system supposed to ever pay off? That will never happen...

That sounds even worse...Could you explain why?!
Other passive houses manage with a 1500 watt heating element...
@Beno, with systems like Euromac2, you can pour walls and ceilings simultaneously.
The maximum pouring height according to the manufacturer is 3 meters (10 feet). Of course, it is possible to exceed this slightly with careful safety measures.
In my house design, I rely entirely on electric power (tankless water heaters, infrared heating).

Beno341234 May 2019 12:32Ok, that doesn’t sound bad. I’ll need to do some research on Euromac2.
If you can generate your own electricity, that’s a great concept. And if the tankless water heater breaks down after 15 years, you just buy a new one for 300 euros…
