Since I mentioned my old office in Hong Kong, here's a pic. The one with Hitachi near the bottom. You can see there are floors without windows because these are empty for fire escape and preventing fire spreading throughout the whole building. In case of fire, we were supposed to walk down/up stairs to those floors and wait for rescue if escape routes are blocked.
The twin buildings used to be the only commercial buildings on the water front (great place to watch fireworks during Chinese New Year on the harbour) but after I left, buildings popped up left and right. The most prominent one is the HK Convention and Exhibition Centre right next. This was where the historical ending of the colonial era of Hong Kong in 1997 took place. The ceremony was held inside the centre. If you look a little closer at the left bottom of the pic under that "I" of the "Hitachi" of the building I mentioned above, there is a golden bauhinia statue
Bauhinia is the official flower of Hong Kong and it's on the new flag after returning to China.
This is what it looks like. Total disharmonic with the buildings around
