This week, I'm sharing with you an advertisement for the launch of Calendon Apartment Block at 7 Hatton Street, Ryde from 1971 (The "road" is an actual error). Two bedroom apartments were on sale from $14 950. According to the RBA Inflation Calculator, this is the equivalent of $149 140 today.
Hopefully the views of the city are still around for those up at the top.
