# A building on top of a parking garage, adjoined buildings

 1 Situation: A group of 4 buildings immediately adjacent to each other that constitute one industrial location. 3 of the buildings are on "ground level". The 4th building, however, has two levels. The bottom level, which is open on two sides, is a parking garage. The top level is warehouse, same as the other buildings, and is on the same level as the other buildings. The bottom level isn't quite a basement, but if I mark it as "ground level" and the other buildings are also "ground level", you wuold get the impression that you can walk from buildings 1, 2, and 3 directly into the the parking garage, with a warehouse above you. That's not the case, as in relation to the other adjoining buildings, the second story is the same level as the other buildings' 1st story. The building closest to the camera is on top of a parking garage, which is built into the depression. How do I tag this? asked 22 Jul '14, 18:30 TylerSchwend 125●5●5●14 accept rate: 0%

 1 Hi TylerSchwend, if the buildings are separate tag them accordingly as three buildings even if theres a layer on top. And add levels as well. Or tag it using the 3 D rules, look here http://wiki.openstreetmap.org/wiki/Simple_3D_Buildings answered 22 Jul '14, 21:30 Hendrikklaas 8.7k●184●216●358 accept rate: 5% 2 I understand that the buildings should be separate, but I'm struggling with the building that is 2 levels, with the top level being a warehouse that is attached to the other buildings' 1st level. (24 Jul '14, 14:11) TylerSchwend Please read buildingparts dot 2 & 3 join the upper levels by using building:part=yes area a building part=yes allows you to join the upper levels independent of the lower levels.

(24 Jul '14, 18:19) TylerSchwend Each building is a multipoly, with the walls/unenclosed ways being members of those multipolys. Since they are separately constructed buildings which could be free-standing, I don't think it's quite appropriate to tag them as "parts". Besides, Building:part does not allow the use of relations. For now, I have simply designated 2relations for the parking/garage warehouse building that uses the same boundaries. The "level" tag is different on the two relations. I don't know how to designate that "level 0" on one building connects on level ground with "level 1" on another building, but oh well. (24 Jul '14, 20:47) TylerSchwend
