The city's first capsule apartments, which were built by a 75-year-old retired engineer in April, are facing a mini-wrecking ball after the city released new regulations that effectively outlaw them.

The draft rules for housing rentals were posted on the Beijing municipal government's website on April 30 and will remain online until May 15 for public comment.

According to the draft rules, the per-person size of a rental unit should be no less than 10 square meters and each person's individual living space should not be smaller than 7.5 square meters.
