It was done in exactly 28 hours and 45 minutes.

The Chinese company Broad Group has unveiled the unusual house that was completed in record time in Changsha.

The housing is made of prefabricated panels made of stainless steel. Modular structures are easy to move because they have standard container sizes, and as can be seen, three cranes can be used to tow a building at an amazing pace.

Homes made using this technology weigh one tenth more than homes made using traditional technology and can even be built on a new site after demolition.
