Copyright prevents us using Google Streetview for mapping, but we
can use it for illustrative purposes.  https://goo.gl/maps/o6ribodaAqUhvak2A
That group of five dwellings was originally called Priory Terrace (the name
is not part of the address and few people know it used to be called that).
They were built at the same time by the same builder and are listed
by a heritage organization as being of significant value.

Talk a walk to the north-east (left in the image) and you will see a long
line
of conjoined buildings of different styles.  Most (all?) of those other
buildings
were built after the first 5, yet it would be perverse to describe
them as extending or enlarging those original 5 dwellings.  They're
houses that happen to share side walls (because it's cheaper and
lets them take up less room).

I said this earlier in the thread, but I think it is still applicable:

Because if you followed that Streetview walk, you'd have countered 33
dwellings in that terrace.  It's nice to be able to give them addresses.
Because they're of different sizes, it's nice to show where the boundaries
between them are.  This is the start of that walk:

My opinion counts for no more than anybody else's, so you are free to
disregard it.  Redefining established use of a tag is problematic.  To say
the least.
