I mean, yeah. It's just a different style altogether. Parlors and room number has nothing to do with what the house looks like and the architectural era it belongs to.

It would be more accurate to say that it smacks of the gilded age (a time of the greatest wealth disparity in our history) than of the civil war era, even though that still isn't quite right, as the Victorian era is its own thing outside of the Edwardian era.

The US has had more than one age of servitude beyond just the obvious slavery era, sorry to say. It's kind of our brand.
