Hi David,

I would say no, since building:part is used for when more than area makes
up the same overall building, eg a conservatory, garage, extension, etc,
joined to a house. In a terrace each property is its own thing, despite
having party walls, and, in the cases highlighted in this conversation,
sometimes the terrace considered as a whole has something special (name,
date, etc) that's not particular to each house in the terrace. I wouldn't
consider individual retail units in a shopping centre (if drawn as areas
and not simply as nodes) needing to be tagged like this either, and
similarly you would have an encompassing building with the centre's name.

Those are the conventions laid down by others I've picked up on over the
years but that's not to say they're the only way, or even the right way, of
mapping these things. It's a fine line in some situations.

Regards,
*Paul*
