Girlfriend said her home is on the fifth floor. What kind of community needs floors?

Not what kind of community decided to draw lots. This means that when the house is demolished and rebuilt and moved back to a new building, it is not clear who is on the first floor and who is on the second floor. If that's the case, the head of the demolition office has long been cut off, so it is allocated by district lottery, so that the people can be calm and resigned.
