I’ve used addr:flatnumber occasionally, but doubt anything currently uses it judging by the overall low usage figures:
http://taginfo.openstreetmap.org/keys/addr%3Aflatnumber So in your example it would be something like addr:flatnumber=1-12 addr:housename=Honor Oak Mansions and add the building to the associatedStreet relation. Ed From: Tom Chance [mailto:t...@acrewoods.net] Sent: 03 May 2012 14:43 To: talk-gb OSM List (E-mail) Subject: [Talk-GB] Addresses for blocks of flats Is there a good way to tag flats within a building so that it is clear the flat numbers (e.g. 1-12) correspond with the building and not with the street? These are two examples I'm struggling with: A block of flats, 1-12 Honor Oak Mansions, sits on Underhill Road. The block doesn't have a number for Underhill Road itself that I can see. If I add the block to the associatedStreet relation and say addr:housenumber=1-12, or just go by addr:street instead of a relation, it looks like that building contains 1-12 Underhill Road. It seems I can only omit the flat numbers and leave it as Honor Oak Mansions on Underhill Road to avoid confusion, and perhaps leave the flat numbers in a note or stick them into the addr:housename. Or more complicated: a block of flats that itself is numbered 234-236 Peckham Rye, and within that block there are flats 1-18. If I add the building to the associatedStreet relation with addr:housenumber=234-236, there's no way to also say how many flats there are. But if I say addr:housenumber=1-18 it looks like that building contains 1-18 Peckham Rye! The only hacky solution I can think of is to put the flat numbers in the addr:housename value so it's there, albeit not easily found by a machine. Should I be nesting relations? Has anyone else come across a neat trick to solve this? Tom
