House names / numbers at The Peak
Addresses around the Peak have changed over the years.
First there were a small number of grand buildings, and addresses were simply "<Name of the house>, The Peak".
The number of houses increased, and at some point numbers were used. #1 was, not surprisingly, Mountain Lodge at the top of Victoria Peak. From there numbers increased in a roughly south-eastward direction, reaching #566 at the end of Middle Gap Road on Mount Cameron.
Today addresses follow the more usual <Number, Road> format. So "566, The Peak" is now "24, Middle Gap Road".
Does anyone know if the changes just happened gradually over time, or if there were formal dates when addresses changed?
