Part of this is modern house construction too (at least where I live in Europe); the living room / kitchen is just one big room, and upstairs there's two bedrooms (one of which can be split up).

I simply don't have the space to dedicate a room for one specific function. I'd love to be able to e.g. have a guest/living room with no tech, an office room for working, etc on top of separate bedrooms for everyone, but that's only possible now in older houses starting at €600,000 in the more remote parts of the country.
