So, first, a lot of the architectural choices (especially if they were picked out by the homeowners and not by the architects) are done to ape (poorly) aristocratic and "Old Money" sorts of dwellings...so, making fun of them on a classist line is semi-acceptable.

The real problem is that the architecture is just plain bad. Space is wasted, exterior are marred by design details meant only to suggest a style of building without any of the things that make them useful, interiors waste space and destroy any efficient attempts at heating and cooling--there is no defending that.
