In June 2025, the world’s highest-altitude and largest-scale pressurized building complex at the Xijiang Huoshaoyun Lead-Zinc Mine was completed and delivered. The high-altitude pressurized buildings are customized high-quality houses for plateau areas, which are globally pioneered by China Construction Third Engineering Bureau Group Co., Ltd., a subsidiary of China State Construction Engineering Corporation.
Through a series of environmental regulation technologies such as pressurization, the buildings adjust indoor environments, including air pressure, oxygen concentration, temperature, and humidity to levels equivalent to those in plains. As a result, they are able to transform plateau environment conditions into those in plains and solve health issues like high-altitude sickness and long-term physiological damage caused by low pressure and oxygen deficiency. Currently, the technology has been applied to scenarios including national defense, scientific research, engineering projects, and tourism accommodation, with several dozen plateau projects implemented.
As an upgraded version of this technology, the Polar Scientific Research Pressurized Buildings have reached Antarctica with China’s 40th and 41st Antarctic scientific expedition teams. The complex will provide work and living guarantees for researchers at the Kunlun Station, where the average annual temperature is -52.5 degrees Celsius and the altitude is 4,087 meters.
