>>2930190 (OP)>McMansionCheaply built gigantic architectural frankenstein's monster that was usually made to the prior owner's "dream house" specs and they did a bunch of questionable, ugly things to fit it all in.
>BarndominiumBasically just a small house with a giant garage/workshop attached, but seems to follow a singular style and focus on functionality. The issue is that, like the McMansion, you are building an unusual structure tailored to what you want that may not be desirable to others 20-40 years down the road.
