I think it's quite normal to live in a 100+ year old building in a European city center. Though they're usually made from brick and not concrete.

And do people who have built their own house usually demolish it and move on after just 30-40 years? That's when you've just paid off your mortgage, heh.

At my parents' house, they just replaced the roof, which was well over 30 years old. The house itself is over 100 years old and completely fine to live in.
