At least 10 people had died by Friday morning after a building collapsed in Shanghai on Thursday.
Fifteen people were being treated in hospital after the roof of a former car repair shop that was undergoing a conversion collapsed.
The 15 survivors and the 10 people killed were pulled from the rubble in a search that involved more than 150 rescuers.
The building, located beside Zhaohua Road in Changning district, was formerly a Dongchi Mercedes-Benz repair shop, which closed earlier this year.
The building was being converted into a commercial complex with restaurants, shops and offices.
The new building was scheduled to open by the end of the month.
Some local residents said that there had been complaints about the renovation work, which was being carried out round the clock and involved the restructuring of a large part of the building.
The building covered an area of 3,000 square metres and about a third of it collapsed.
The rescue workers and 24 fire engines were dispatched to the scene, the local fire bureau said on its Weibo account.
Locals said they believed most those killed or injured in the accident were construction workers.
