A developer in China has set a new record after building a 57-storey block in less than 3 weeks.
The Mini Sky City building was put up brick by brick at a rate of three full storeys a day in Changsha, the capital of Hunan Province in south-central China.
It has 800 apartments and office space for up to 4000 people.
Being a prefabricated building, most parts were made in a factory, transported to site and stacked up on top of each other.
