I have data from a ground survey which collected information on the structure of buildings. The options are wood, concrete or semi-concrete and wood. I now want to upload this information along with some other information to OSM. How would I tag the semi-concrete and wood ones? I've read the OSM wiki on using multiple tags, but I'm still not quite sure, so any help would be appreciated.

The solution I came up with was to use the following tags/values if I have a building with mixed material:



or could I use building:material=wood;concrete

as this is not a top level tag?

Many thanks for your help.

Do you mean a wall would have both wood and concrete? If they are on separate parts, building:part= can be used.

@Kovoschiz, yes exactly, the buildings are built with wood and concrete. Many thanks for the tip with building:part, I didn't know that existed. That is super useful. I just looked it up but I think I probably shouldn't be using it in my case. The building information I'm uploadin at the moment are only point locations ( I should have stated that in my question), but according to the wiki building:part should only be used on polygons, I might go with what @Hendrikklaas suggested below.

Hi, you should make a choice for instance the first floor or basement, that is what you see at first. But your own suggestion wood:concrete is a good one. It is not populair.
