Social distancing in 100 square feet: Hong Kong's cage homes are almost impossible to self-isolate in

This photograph taken by Benny Lam for the Society for Community Organization shows the inside of one of Hong Kong's "cage homes."

Hong Kong (CNN)Before the pandemic, Lum Chai used to go to the park and drink beers with friends to escape his tiny living quarters. Now the 45-year-old walks the city's streets alone to kill time and keep away from his neighbors.

Vigilantly practicing social distancing at home isn't an option for Lum. He lives in one of Hong Kong's "cage homes," subdivided apartments that often have space for only a bed and some clothes. His closest neighbor is just a few feet away, inside the same room.
Cage homes are usually smaller than 100 square feet, only 25 square feet larger than most of the city's prison cells. Bathrooms are mostly communal and often there are no kitchens -- just plug-in hot plates. Units are mostly divided by makeshift or removable walls.
    Lum, who is unemployed, said he pays 1,800 Hong Kong dollars ($232) for an apartment divided between 10 people.

    Lum's situation is extreme, but not unusual. Nine in 10 people in Hong Kong live in an area smaller than 753 square feet -- or 70 square meters -- and yet pay some of the highest rents and property prices in the world. The average cost of a home was more than $1.2 million last year, according to real estate investment firm CBRE.
