Which material to use for the house? Is brick without insulation possible?

As the title already says, we are considering which masonry we can use if we want to build thin and without additional insulation?

"Thin" would only be feasible with insulation (24 + 12 or 17.5 + 16 for example), but 36.5 cm is definitely possible monolithically, using various building materials. Exactly which one, my mantra is: the brick that the builder is familiar with, not to "carelessly" change to one that is praised higher somewhere else (because every forum opinion faction has its favorite brick, but so does every construction company).
