Look, you'd really have to read the blog before making comments on it. Always a good idea. First read - in this case, all of it! - and then talk about it. Please. The blog explains very well how to recognise a McMansion and it really isn't that hard.

As for why McMansions are bad, there are plenty of explanations given in this blog (areas hard to reach, cheap materials, wasted space, water damage after a short time, etc...). Just look at this one image, plenty of reasons: http://99percentinvisible.org/app/uploads/2016/10/18-mc-esch... (dust collection areas, unsafe fireplace, etc.)

McMansion builders are not doing thoughtful design with some sort of aesthetic vision, though. They're slapping together the cheapest materials they can find, as quickly as possible to make the highest profit. That's why it ends up looking bad. They didn't use 5 different kind of windows because they had some design vision that requires it. They used 5 different kinds of windows because the contractor said "Hey, I've got a bunch of different windows left over from other jobs, let's use them here so we don't have to buy new ones."

As it stands, it's a McMansion of an article. A lot of things thrown together without any rhyme or reason, sold to people who don't know any better, and marketed as the epitome of high culture. It did nothing to further my understanding of what is a good house and what is a bad house except "if you cut it in half, you have two identical halves... most of the time... but not always".

I understand why McMansions suck, and I can use the same reasons to say the same thing about the McMansion Hell articles. They're full of "this is bad" without any "this is why" attached. And a lot of the "this is bad" stuff appears on houses that are definitively not McMansions (like villas and 13th century manors).

I guess each individual post is disjointed. they aren't meant to stand alone but be part of a collective.
