Depending on the walls, generally at least in my country walls are made of clay bricks, so any hammer drill will work, but if you want to drill too close to the ceiling, or the ceiling you will need something better.

I ended up buying a rotary hammer because of this, holes on the floor (doorstoppers), ceiling, or walls right close to the ceiling was impossible with the cheap hammer drill, along with a good SDS+ drill bit feels like butter now.

Yes, I had good experiences working with brick walls so far - but a lot of very modern construction (here in Switzerland) uses a lot of concrete, sometimes even exposed concrete in living spaces [0].

I really don't know if any of the designers/architects involved have ever tried living in those apartments. I think a lot of them would choose different materials if they had to do their own DYI.

Oh, they do.

Concrete has great thermodynamic properties for living comfort. It cools at day, warms at night, transfers from cold parts of the house to hot ones, etc.

It is there on purpose (and not too difficult to drill into with a "Bohrhammer", rotary drill(?), i.e. the ones with SDS(+)).

Actually, the brick-walls we have (hollow bricks with flimsy thin walls) were harder for me to figure out. They need really careful drilling with the right tools, otherwise the brick shatters and nothing will take grip.
