Re terraced/semi-detached houses; I found this comment from https://www.reddit.com/r/openstreetmap/comments/vu0hgl/whats_the_best_way_to_split_a_house_in_two_is_osm/ interesting

>You should first consider whether it makes sense to split a building. The addresses can be represented as points, if the buildings are one unit, then it is better to leave them together, so that you can specify buildig_level, roof_shape etc. together for the whole building.

What do you think?
