The 15-story Ark Hotel in Changsha, China was built in six days using factory-built parts brought to the site by a convoy of trucks. Completed on June 11, the finished building had triple-glazed plastic windows, heat insulation, LED lighting, and HVAC systems in place, while using no stationary cranes. The level 9 earthquake-resistant building was also sound proofed and thermally insulated.
The foundations were already built, however, using the prefabricated model of shipping in factory-built parts allowed the Arc Hotel to be erected while claiming a 1% construction waste. Dubbed the Sustainable Building, the builder states the structure combines environmentally friendly, comfortable, and secure elements. The video claims there were no injuries in the construction process.
