Hello everyone,
We are currently planning our new build and want to construct the exterior walls monolithically with Poroton blocks. Now the question is whether we should also build the load-bearing interior walls from Kalksandstein (calcium silicate bricks) or use Poroton for those as well. We would prefer Kalksandstein, among other reasons, for better sound insulation and the possibility of using standard anchors.
Some construction companies say there might be slight stress cracks, while others say this is not a problem since mortar shrinkage is greatly reduced with modern thin-bed mortar.
The non-load-bearing walls would be made of drywall panels. Would you recommend this, or would you suggest an alternative?
Do you have any experience with this? Have you perhaps built like this? We would be grateful for any tips.
Best regards

I have only followed your different threads on the side and find it always difficult to comment on individual topics without knowing the full context.
I get the impression that, while you are positively engaging with the various subjects and trades, you might eventually get lost in between because each topic involves seemingly endless options, advantages, disadvantages, and perspectives.
It would probably make sense for you to first present your project as a whole, including the floor plan, site plan, etc., according to the questionnaire. From that, further questions will arise that can gradually guide you onto a good path.
In my opinion, the most important thing is your needs and the living atmosphere you want within your possibilities. Whether there is a drywall (gypsum board) or a Poroton masonry wall is comparatively insignificant.
I have lived in various types of construction, and the perceived difference does not come from the choice of bricks or the timber frame wall, etc.
Therefore, I would suggest starting here in the forum again from square one, because many of your questions may become irrelevant over time through other, more fundamental decisions.
As you are approaching it so far, I fear that you might get overwhelmed by too much detailed information and not make any real progress.

I think we just have different writing styles 🙂
We are building a house, but we are not building it ourselves. So, your favorite choice from the list of general contractors builds these walls entirely with gypsum boards? That would make me think twice, because this is very unusual for general contractors (but exactly the opposite for multi-story residential construction subcontractors), which suggests that this construction company does not mainly build single-family homes.

The way you’ve approached this so far, I fear you’ll get overwhelmed by too many detailed pieces of information and won’t really make progress. Exactly, the completed questionnaire and the plot of land are the best content for an initial post. Yvonne did not point to the textbook example of how to drive a cart into the mud with a guaranteed failure for no reason. The general contractor clearly failed there, but the homeowner also took the perfectly coordinated initial approach. Without such excellent preliminary work, the crash landing would have been only half as loud.

That’s why I would recommend going back to square one here in the forum, because many of your questions might be resolved gradually through other, more fundamental decisions. Most questions will be solved by shifting the strategy from scattered individual question threads to a single "central thread" focused on the project as a whole.

P.S.: Then I don’t understand the whole question:
Do you actually mean: “Should we choose the general contractor who mixes the red blocks with one type of white blocks or the one who mixes the red blocks with the other type of white blocks?”
If the discussion is about the same candidate who would build the walls
- outside with Poroton
- inside non-load-bearing with gypsum boards
- inside load-bearing by default with Poroton but on your request also with calcium silicate blocks,
then I clearly see you as urgent cases for an independent construction consultant.
With a mixed phone consultation like “for option X, 38% come from the forum, but 43% from the handball team, and even only 29% from the church choir, so we either take Y or toss a coin,” you won’t get anywhere!

I find this very contradictory:

sometimes you talk to a salesperson, managing director, appraiser, or architect. That’s why the conversations were very different. there is a huge flow of information that a layperson can’t really manage, and now a kind of “mishmash villa” is being put together from it.
Metaphor:
You can’t really say anything against red and white on fries, but when the hotdog sauce is added because it provides sweet and sour flavor, plus mustard as well as remoulade, which is normally meant for the fish burger, then it seems they got overwhelmed by the extra sauces on the snack bar menu.

.. I was not aware that I could post complete projects here.

If you are referring to the same candidate who plans to build the walls
- outside with Poroton (clay blocks)
- inside non-load-bearing with gypsum boards
- inside load-bearing normally with Poroton but, based on your change request, also with sand-lime bricks,
then I clearly see you as urgent cases for an independent building consultant. Using a mixed guessing game on the phone like “for option X, 38% come from the forum, 43% from the handball team, and only 29% from the church choir, so we either choose Y or toss a coin” won’t get you anywhere! What is so unclear about the question? Mixing red and white bricks? Or better not?
What would you consider a reasonable combination?
