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.

Oh no, before going into detail, you first have to ask yourself why you want to insulate a house to Passive House standard, only to then heat with electricity and end up with higher heating costs than a standard building code (energy saving regulation) house...
A fireplace in a Passive House is also a no-go.
The most important thing is to "keep it simple." Combining a hundred different heating options ends in disaster.
Well, I find the poured polystyrene blocks creepy, but that’s definitely subjective—whatever people like.

I find the concept somewhat inconsistent. On one hand, there are simple, durable tankless water heaters that are also inexpensive, and on the other hand, a wind turbine and battery storage—both of which, according to all the sources I know so far, never really pay off. If you see it as a hobby, that’s fine; from an economic standpoint, no. With the additional investment costs, you could heat for a long time.
What the utility companies sell as a "power cloud" is just marketing nonsense that also costs around 20€ per month. Your own electricity is only returned virtually.

Beno341235 May 2019 10:36The house is being built in a windy area with open exposure from the west, south, and east. This means it can become cost-effective within about 15 years.
However, the exact concept is not clearly defined yet.
The focus is on a small fireplace located centrally in the living area, which can heat almost the entire ground floor as well as the buffer storage.
The tube collectors cover the hot water production from March to October, and partially in winter as well.
If the wind turbine is actually installed, there will also be an electric heating element in the buffer storage to avoid feeding electricity back into the public grid and to use all generated power on-site.
For climate control, there are three Mitsubishi inverters, allowing both cooling and heating.
A tankless water heater is included only as a backup if the available energy is not sufficient.

Beno341235 May 2019 16:03What exactly are you referring to now?
Wind turbine, water chimney, collectors, and inverter in combination.
Why are you doing this? Are you interested in the technology, or have you always wanted to build something like this?
As mentioned, it is neither economical nor simple. I have no knowledge about wind turbines, but when you write "it can pay off after 15 years," it sounds like when someone says "solar panels can pay off after 5 years." It is possible, but not the usual case.
