We've got a good example here, not actually "horrible", but awfully dull and boring-looking; after WW2 a lot of prefab houses were put up "on a temporary basis" all over the UK... there are still hundreds left, and one small row (the last in town, I think) is just ten minutes' walk away. They've been totally refurbished at least twice that I know of, and I sometimes wonder if the only thing holding them up is the decorative brick lining that was put on last time.
