Classics; people're too obsessed with the ability to do what they want with their homes, and instead of making something good, they make a structural representation of the Rocky Horror Show.

I like large 3 stories, but to be honest a good house can be tiny and a horrible one huge. I'd agree with Linaeus that having more room for embellishments is nice; I tried to add some to the library and there simply wasn't room while still having room for the books!
