Hello Anna Map,

welcome to OSM.

Please do not use "Building" as a name - this makes no sense https://wiki.openstreetmap.org/wiki/Names#Name_is_the_name_only

Building is the key and you can use the tag to describe the type of a building with specific values e.g. "house", "church", ...

See wiki for the rules:

https://wiki.openstreetmap.org/wiki/Key:building#Values

Thanks & Happy mapping
