I'll go along with what Wiki says and allotments seem to be for a very specific use - individual gardening plots for families. In reality, these are allotments in name only ("dārzniecības kooperatīvs"), but not in practice. These are now almost all individual houses, summerhouses and cottages. So I mapped them all as residential until there's an adopted use for "cottages" or something like that.
