Examples: https://www.irishtimes.com/life-and-style/homes-and-property... - Fake Georgian townhouses. You're still left with a four storey house, which isn't super-practical, and they look ridiculous.
https://www.pjhegarty.ie/projects/esb-head-office/ - Replacing a distinctly un-Georgian Brutalist thing which itself replaced a row of Georgian houses back in the day. Again, looks silly, but if they'd played it completely straight they'd be left with a pretty impractical office building.
