ᐅ An above-ground basement?

Hello everyone,

So far, I have only been reading along in the forum and found a lot of interesting information.

Now I am planning to build a single-family house.

I am surprised that there is so little information about concrete in private construction, even though in real life I have already seen several architect-designed houses made of exposed concrete. I don’t want or am allowed to build something that extreme, but I am interested in whether the cost-effective construction method of a basement can also be used above ground for living spaces. Manufacturers of prefabricated basements advertise how versatile their products are. But is it really possible to build something other than a basement this way?

Does anyone have experience with KFW-55 compliant concrete walls for the ground floor of a single-family house (essentially an above-ground living basement)? Does this work in practice?

Thanks in advance for all your answers!

p.s.

Please, let’s not discuss breathable versus non-breathable walls in this thread. Thank you.

Also, I am aware that installing electrical wiring inside concrete walls is quite complicated. However, this can largely be avoided through design by placing installations, light switches, etc., in drywall interior walls. Theoretically.
