We thrashed out ideas on th wiki the other day and decided upon the following:

The buiding areas are tagged with building=residential (or
building=whatever if its something else)

The nodes are also tagged with buidling=residential and have an
additional ref=# on them for the house number.

Will document this in Map Features if it looks to work out ok once rendered.

Cheers

Andy
