It is amazing to see what is On Top.
This is what you find on top of Hong Kong residential high rises.
Grass, swimming pools of various sizes, water features, rest areas, trellis, planters with plants, sun bath chairs.
Also, fans for cooling water system etc.
On commercial high rises, there is a different view.
You have antennas and satellite dishes, devices for lifting gondolas for cleaning and maintenance of external walls etc.
For some of buildings, we cannot even see what is on top.
