Ok, got it. So addr:place+addr:housenumber for those. And a point inside the building for alternate address, if any. I still have to decide on a primary though.
Another minor question: normally, for the building number and suburb, the building number is prefixed with “бл.” (short for блок, meaning appartment building). It helps differentiate between street number and building number. Shall I include it in the addr:housenumber, and should I have an “en:*” field for translation?
