Note: Assume annual completion of 28,000 public housing units and 18,000 private housing units in 2017-2026; 16,000
public housing units and 11,000 private housing units in 2027-2046, and no demolition of old buildings in the next
30 years.

1. We collected data on the age of all private and public housing in Hong Kong and constructed the
building age pyramids. It can be seen that in addition to our population, our buildings too are
aging rapidly.

2. In 2016, only about 9% of all housing units in Hong Kong were over 50 years old. Assuming that
no buildings will be demolished in the next 30 years, by 2046, OHKF estimates that about 47% of
them, which contains nearly 1.5 million units (of which nearly 670,000 were public units and
850,000 private units), will be over 50 years old. This will seriously a ect the living environment
and quality of the Hong Kong people. In view of this, OHKF believes that we need to respond to
future redevelopment needs and take preemptive actions.
