The houses are also always... the same. The variations in it are where the rectangle windows are and the length / width / height. But that is it.
I predict that in 20-30 years these houses will be seen as one of the ugly architectural trends of my time.
While houses that were built a century or even more ago (and that still stand) are lush with these ornaments and still retain a sort of beauty. [2]
I've lived in one of these type of houses and while they have some impracticalities because they have been built in a different century the outside stays a thing of beauty and you could guide people to your house purely because of how it looks.
Currently my wife and I are looking to build a new house and one of the requirements that we have for our architect is to build it with small details on the outside and a bit more classical than the current trend is.
