A huge amount of American suburbia is soulless copy/pasted McMansions and copy/pasted townhouses. Lucky for us, my father was a building contractor so he designed and custom built the home I grew up in, but AFAIK that is super rare nowadays, and is limited to rich people who can afford something custom. Everyone else in suburbia gets cut/pasted houses with the same faux brick facades, tacky arches, and cheap plastic siding on the walls that don’t face front.
