New build 2-family house in BW using Neopor formwork blocks - construction companies?

Hope my thought process was clear enough for now...

At least the description makes it possible to analyze the chain of thinking errors. I’ll save detailed floor plan criticism for now, only as a PDF would this reach many fellow readers here. What is clearly recognizable: this will be an architect’s house. High demands must be placed on the implementers, including their cultural familiarity. Take a look at what kind of architectural taste prevails in the home countries of your preferred construction workers: I predict many unfamiliar detail connections = critical points in your house. Don’t be fooled by the special stones for 45° walls etc.: the do-it-yourself systems target people who, because of a third child, have to translate their budget for a 9x9 m one-and-a-half-story witch’s cottage to 9x11 m, and then dad has to do the masonry himself. Your house design is definitely too atypical for such systems. You might achieve the desired stiffening wall with such systems, but not much more. The problem with formwork stone systems is that while you can easily build shell structures as a layperson, then the skilled trades have to core drill where they would otherwise use lighter equipment to chase grooves. That won’t make anyone happy. Maybe you should consider hiring a general contractor from Central Europe right away (Eastern Europe is not geographically correct here; the term is just a habit from times when that was politically “East”). You should then have them adapt the design so that details and routines match. I can gladly put you in touch.

Thank you 11ant for your contribution. But you write a lot of meaningless content. Please be factually clear or stop. I am happy to accept contacts.

Best regards, Alex

But you write a lot of meaningless stuff. Please be factually clear or stop.

Where is there anything meaningless (except maybe that PL / CZ / SK & Co are not "Eastern" Europe, which is off-topic in terms of building themes)?

so in posts there is a lot of content, you just have to be able to understand it (and also want to!).

I want to understand. I have been working my way into the subject for months. Many say the system is useless. But no one can specify why. Please provide fact-based clarification. Preferably from [Bauherren] who have direct experience! Thank you!!

- Self-build house few companies install the material - Problems with interior construction e.g. because of core drilling - Every cabinet and every shelf must be fastened with screws long enough to go through the Neopor

Even the best system won't work well if companies work with it without experience

Consider which trades you want to take out and assign yourself not only regarding the warranty. Every trade blames another and you are the ping-pong ball in the middle.

Nearby, in 2015, a family built a solid wood house to passive house standard. Planning, shell construction, and material came from one company. For every trade, he could say I’ll do it myself, no you do that.

Don’t fixate on one building material. Make a list of your requirements, what you will do yourself, and where you can actually get companies. Poles and Romanians don’t wait either and have partly adjusted their prices at least here with us. Then find a construction partner ideally with your preferred building material.
