Aesthetically pleasing it is, but also way less practical and way more costly to build. Nice stone facades can't have any thermal insulation on them (and having it inside is less than ideal), in Europe this would be a big problems apart from very south regions. I think mcmansions are trying to find some middle ground, but they don't seem to receive much love (those are not so common in Europe so just judging from far).

Medieval castles can be very pretty to visit too, I wouldn't want to live in one if given modern choice regardless of wealth, even if ignoring all the red tape for any sort of change or even repair.
