A Chinese company has built a 57-story building in only 19 days in the town of Changsha, China, a construction company official told ABC News.
The project, called Mini Sky City, was built by 1,200 workers and includes 800 homes and working space for 4,000 people, the official with Broad Sustainable Building told ABC News.

The building could be built so quickly because it was made of pre-fabricated parts. Nevertheless, it is earthquake-resistant and safer than others, the company official said.
