Many European countries have laws requiring old or ancient houses to be maintained by the owner in the manor they existed previously. Getting thatched houses rethatched and stone remade and such. That along with the lower frequency of storms, the less compact residential distribution, and the focus on industrialization made many of the oldest american homes ones that fit in with modern ones. There were a lot of Americans who would have their old shacks torn down to get the new fancy ones.
that’s a fair point! I will say the US has similar preservation laws that have existed since the 60s, which had thankfully protected many historic homes. I wouldn’t fault it on America’s age however I would fault it on these points you just mentioned. Older homes were also built to be more weather resistant than homes built today. Newer neighborhoods have a focus on building as many houses as possible as cheap and quick as they can which means they cut corners and use poor quality material
