How old is this house approximately?

I tapped against it, it's more (direction) plastic, so not a real brick cladding. Now I know for the time being. Thanks

is more (direction) plastic, so not a real facing brick.

You can't tell exactly, but it doesn't seem to go into the reveal (?) With a bit of bad luck, everything was modernized around 1980 - back then progressive materials that are seen as rather problematic today.

It would be nice if a picture here was larger sometimes, so you can zoom in.

Since people have been able to take screenshots on their phones, everyone has apparently forgotten the dependence on image size and quality.

The rest here is just crystal ball gazing.

No, it has just become inversely proportional ;-)
