Hi there LDCMidds13, Welcome to OSM.
I would like to give you a bit of input on this changeset. Ideally each of these semi-detached houses should be split down the middle into 2 houses each with a single value for addr:housenumber. This has the benefit of making it easer for the exact address to be found but also most software don't understand concaternated house numbers like "1 & 2" or "1;2" so it makes it easer for software too. you can see a good example of semi-detached houses i've done here: https://www.openstreetmap.org/#map=19/51.76923/-3.28708
kind regards,
Kits
