As populations around the world grow rapidly, some cities such as Hong Kong and San Francisco have seen a surge in the construction of tiny apartments. Some units are as small as 200 square feet, earning them the nicknames “micro-flats,” “coffin homes,” “mosquito units,” and “gnat flats.”

While some argue the tiny living spaces are not adequate to live in, others have gotten innovative with their small space, downsizing their belongings and embracing the tight squeeze.
