An 11-storey building was erected in less than 29 hours in Changsha, China, marking a global first. This rapid construction was made possible by the Hunan Yuanda Technology Group's use of stainless steel instead of reinforced concrete. This modular building, often referred to as a 'living building', can reportedly be assembled and disassembled easily, and is built to last a thousand years. The technology combined prefabrication methods with easy site assembly, facilitating faster construction times. Not only is the structure resistant to physical stresses like earthquakes and typhoons, but it also possesses excellent thermal insulation properties. This method of construction greatly reduces carbon emissions and is cost-effective due to large scale material purchasing and increased factory production efficiency. Despite potential skepticism concerning the stability and durability of such structures, this innovation demonstrates China's continuous advancement in the construction industry.
