Different home systems, how solid is a solid house really

I am currently thinking about different house systems, there are loads of them. Why is a brick house called a solid house, 80% of the brick is air, so nothing solid about it, with the new bricks you already have problems with attaching heavier things.

A "wooden house," that is a post-frame house, is not really a wooden house, it is just a post-frame construction stuffed full of insulation. Hmm, how do you attach anything there?

Concrete house with Styrofoam blocks, well, it is pretty tight, so no chance for moisture to get outside, diffusion-tight, also not ideal, it should be diffusion-open. In addition, insulation with Styrofoam is not my thing either, it is not pressure resistant, poor summer heat protection, etc.

Now I came across something, I think it’s amazing, what do you think about: A house made of solid wooden walls, that already looks great, I have already visited a construction site. So actually, I’m blown away, what is your opinion on that?

The price is turnkey comparable to a brick house, only solid :)

Looking forward to many opinions

So... If a provider's homepage already presents itself as 'Home - Meine Homepage' - then the whole thing is unnecessary. And even the manufacturer of the wall material still says that an additional 100mm of insulation is required...

It's always advertising, whatever he posts, for the same thing for years ...
