`addr:place=` is used in villages for `addr:housenumber=` numbering each address directly, and matching a `place=` (there's none here) . `addr:place=` also doesn't work when there are housing estates inside villages. The emergent practice in HK is to use `addr:housename=` for estate names, and `addr:unit=` for individual tower units (think Tower 1A for a building split into 2, which fits the wiki description for different stairs) or houses.
