Overseas Large Container Houses
Overseas large container houses are primarily used as temporary, modular building solutions, applied in areas such as event accommodations, emergency shelters, commercial spaces, and high-end residences. They offer advantages like rapid construction, cost control, and flexible expansion, though they may also have living experience issues due to design or budget constraints.
I. Event Accommodations and Temporary Shelters
The Nagoya Asian Games abandoned traditional Asian Games village construction due to budget overruns and instead adopted container houses as one of the accommodation solutions for athletes. Approximately 2,000 athletes were housed in temporary container accommodations built at Nagoya Port. These container houses are based on standard 20-foot or 40-foot shipping containers, with modular installations of walls, utilities, and bathrooms completed in factories, and then assembled on-site to form complete living units. However, due to cost constraints, the container houses at the Nagoya Asian Games had significant hardware shortcomings: for example, single beds were only 195 centimeters long, insufficient for taller athletes; room heights and aisles were narrow, with poor sound insulation, and each unit was equipped with only one air conditioner, resulting in low living comfort. Additionally, the container housing was far from some event venues, with commute times exceeding one hour, further affecting athletes' competition experiences.
II. Technical Advantages of Modular Construction
The core advantage of container houses lies in their modular design concept. Taking China's exported modular buildings as an example, factories complete precise assembly of steel structures, walls, and pipelines through assembly lines, then load the prefabricated modules into containers for transport to their destinations, where on-site assembly efficiency increases by over 60% compared to traditional construction. For instance, a British retirement apartment project used 63 Chinese-made modules, taking only two weeks from shipment to on-site hoisting completion; the MRDC hotel project in Papua New Guinea shortened its delivery cycle from 14-18 months to 7 months through a modular approach. This model not only saves labor costs (with hourly wages for construction technicians in Europe and the United States reaching 200-400 RMB, while modular sites typically require only about 45 permanent personnel) but also controls steel waste to 3%-5% through standardized CNC cutting (compared to 8%-12% on traditional construction sites), while reducing the use of foundational materials by 60%-70%.
III. High-End and Customized Applications
The application scenarios for container houses are expanding from temporary buildings to high-end residences and commercial spaces. For example, Carol's House in New York, USA, is composed of 15 stacked containers, forming a 5,000-square-foot (464.5-square-meter) multi-story residence equipped with an open living room, five bedrooms, a home theater, and a temperature-controlled wine cellar; the Stockholm container house in Sweden achieves integration with the natural environment through a stacked design of eight containers and was shortlisted for the annual housing competition finals. Additionally, the dual-wing expandable containers produced by Chinese companies for a Chilean project demonstrate the flexibility of modular buildings: a 20-foot container expands to provide 36 square meters of indoor living space, which can be designed as a two-bedroom, one-living-room residence or storage space according to needs, with the sides folded in during transport to improve loading efficiency.
IV. Market and Industry Trends
The global modular building market is growing rapidly, with China as a major exporter seeing prefabricated building exports reach $2.79 billion in the first half of 2026, a 45% year-on-year increase. The explosion of AI computing infrastructure has further driven the construction of modular data centers, such as a mega prefabricated modular data center project in Malaysia that shortened its construction cycle to 10 months (compared to 18-24 months traditionally), with CIMC Group's modular data center business revenue surging more than fivefold year-on-year in the first half. Market research institutions predict that the global modular building market will continue to expand by 2030, with high-end residences and data centers becoming important growth areas.
