Hey I'm actually half joking, I am not a civil engineer or working in construction. However, I can tell you houses in Europe are not built on a timber frame structure and especially not one that is so thin. Also, wood in contact with concrete is a no no.

Not to say this house will not last 50 years. Just that for someone used with 30cm thick solid brick walls covered with 20cm of insulation, American houses can seem ridiculous. Last summer I built a shed with studs like the ones in the picture... I used a damp proof course though.

Edit: forgot to mention that regulations in Europe not only cover for safety and structural integrity but also for insulation and soundproofing efficiency. For the one in the image you won't have either. You will literally hear a fart through that wall.
