In a lot of places in the UK standardising of houses has been happening for a long time. I lived on two public housing estates, both of which featured row upon row of identical houses. The only difference was that the colour of the front doors was varied, but only using about four different colours.

I can think, offhand, of a few private estates in the area that I lived where the houses were all identical in structure. I think that the Brits tend to accept this more than do the Americans.

I must admit that I still find it interesting that, in any one road here in Maine, there can be so many diverse building styles. I think that is one of the major differences I have found here from the UK.
