According to meaning of building=* should be used for building constructed as ruins (for example sham ruins in an English landscape garden). Frequently used in conflict with other building=* values. building=ruins used for house that is an abandoned (but still a building) conflicts with tagging it as building=house.
Due to this mistagging it is a good idea to explicitly mark construction as sham ruins (for example with note=*).
