To say Hong Kong is crowded is an understatement. Over seven million people are squeezed into just 1108 square kilometres. And boy, in some places it's a tight squeeze.
As website China Smack pointed out, the city has 6588 high-rise buildings, which is more than New York's 5818. Hong Kong truly is a "skyscraper city".
In Architecture of Density, German photographer Michael Wolf captured the city's most cramped residences. They look more like concrete curtains than dwellings. The photos are unreal.
