I have already read quite a bit here.
At least from me still decidedly too little – otherwise you should know my #Steinemantra and also my urgent advice to all newbies to show their project as a whole and to subject the design
before any "fixations" to critique (because post alea iacta none of it helps anymore).
So in summary, we actually want to realize the best combo in price-performance-sound insulation somehow as masonry. [ / ] In any case, we coordinate that with the architect. That will also be included in the architect’s planning.
That sounds contradictory: such triangular priorities are postulated rather by people who do not engage an architect without quotation marks and certainly not mandate them including execution planning (service phase 5).
We don’t want clinker and not aerated concrete either.
1. okay; 2. needs explanation!
We already have. Poroton filled or unfilled!
What is the architect’s profession? – if you talked about your sound insulation focus, a professional can hardly lump unfilled and filled porous bricks together!
Stone is out of the question for us for various reasons.
I don’t know that at all (?) You write about a "one-and-a-half-story bungalow," you probably mean a house with a converted or at least conversion-prepared pitched roof floor (without knee wall?); in the attic you will hardly get past gable-parallel lightweight walls at least (which is not bad). Also, that you are a limestone block fanboy, you should reconsider with advice.
