I wasn't sure how this brick is called in US https://cdn.hornbach.cz/data/shop/D04/001/780/491/166/959/DV...

Or this Ytong https://as1.ftcdn.net/v2/jpg/01/99/70/94/1000_F_199709412_vW...

Because these are most common materials used for building houses, (in CZ).

And wanted to distinguish I don't mean classic house made of classic bricks. Because if American see a brick house, they think this, right? https://st.hzcdn.com/simgs/afd1745b0164c256_14-6933/home-des... And this type of house is very rare here. Maybe you can't even build it here, because of bad heat insulation etc.

In Australia, generically (without being specific) "blocks", "Masonry Blocks", "CMUs", or "Concrete Masonry Unit", "Cinder Block".

Likely the same in the US.

Every type has some specific trade name that rarely matters much - your images look like the type that interlock with a specific keying profile.
