Looking in the wiki at this scheme: https://wiki.openstreetmap.org/wiki/File:Indoor2.0_elements.svg it seems that indoor=room is to describe a room (which is delimited by walls). In this case, these objects indeed should not overlap, as there will always be a wall between 2 rooms. If the walls were to be included in the object, it would be ok to overlap the rooms. Unfortunately the wiki (where I looked) didn't explain these basic concepts. FWIW, in architecture you would account for wall thickness (walls as 2 lines) for representation in scales below 1:200 and would use 1 line for scales 1:200 and 1:500. Different layers of the wall (=more than 2 lines) would be drawn in scales 1:1 - 1:25 (according to the materials, etc., in 1:50 you would use hatches to symbolize different kind of wall constructions, but would have generalized drawings without entering into specifics, usually). Cheers, Martin
