Earlier this year, a YouTube video of an American couple unboxing a Chinese prefab house went viral with 2.49 million views. They paid $28,689 (under 200,000 RMB) for a 70-square-meter expandable container home from a factory in Hebei Province. One day after delivery, it was fully assembled — bedroom, kitchen, and private bathroom all included.
The number shocked overseas viewers. In most Western countries, that amount barely covers labor costs alone. What the Chinese factory delivered was a complete, move-in-ready home.
But what many people overlook is this: the biggest buyers in China's prefab housing export wave are not individual families — they are mining companies.
According to China's General Administration of Customs, the country's prefabricated building exports grew from $1.472 billion in 2015 to $4.339 billion in 2025 — tripling in a decade. In Q1 2026 alone, the growth rate hit 45%. Just through the Guangzhou customs district, the value of portable building exports reached RMB 1.4 billion in the first four months of 2026, up 38.1% year-on-year.
Behind these numbers, camp accommodation orders from mining operations worldwide account for a growing share.
A large-scale mine in a remote area typically requires 5 to 10 years of construction. During peak periods, thousands of workers need on-site accommodation simultaneously. Worker housing is not just a logistical concern — it's a critical factor determining whether a mine can start production on schedule.
Using traditional construction methods near a remote mine site faces several insurmountable challenges: high building material transportation costs, local construction labor shortages, and uncontrollable project timelines. In Australia, construction labor rates have risen above AUD 80 per hour. Building a single room using traditional methods can cost over AUD 100,000. At high-altitude mining sites above 4,000 meters in Chile, transporting building materials on foot is practically unsustainable.
Modular construction bypasses these bottlenecks entirely.
The core logic is simple: move as much on-site work as possible into the factory. Walls, floors, plumbing, electrical wiring, and interior finishes are all prefabricated on the production line in a single pass, folded into standard container-sized modules. When the modules arrive at the mine site, a crane positions them, the units are expanded and secured, and after connecting utilities, workers can move in immediately.
It's not building a house from scratch — it's assembling a house that has already been built.
Climate conditions vary dramatically across different mining regions. A one-size-fits-all approach simply doesn't work in the mining camp sector.
For oil field and phosphate mining camps in the Middle East, summer surface temperatures can exceed 50°C, accompanied by persistent sandstorms. Sealing and thermal insulation are the primary challenges. The solution provided by 9States for Saudi mining camps uses broken-bridge aluminum windows with double-layer low-E hollow glass, high-temperature-resistant silicone sealant throughout the container body, and upgraded heat-resistant flame-retardant copper wiring — ensuring air conditioning systems can run continuously in extreme heat without electrical degradation.
For gold mining camps in Siberia, Russia, winter temperatures drop to -40°C, with snow accumulation exceeding one meter. Standard insulation is completely inadequate here. 9States upgrades wall panel insulation to 100mm polyurethane sandwich panels, upgrades the frame material to 3.0mm thick-wall square steel, raises the container base more than 30cm above ground to prevent frost heave damage, and designs the roof with a steep slope for natural snow shedding.
For nickel mining camps in Central Sulawesi, Indonesia, annual rainfall exceeds 3,000mm, and relative humidity stays above 80% year-round. A dual-layer roof design, elevated anti-slip waterproof SPC flooring, and moisture-resistant magnesium board interior panels ensure the units remain dry and mold-free even through months of continuous rain — in many cases delivering a more comfortable living environment than local traditionally-built housing.
Coastal mining sites in South America face high salt spray corrosion. For camps in coastal Peru and Chile, 9States applies phosphating treatment followed by fluorocarbon anti-corrosion paint to all metal structures. All exposed hardware uses 316 stainless steel, creating an industrial aesthetic that complements the region's signature red copper ore.
Why are Chinese companies succeeding at this? The answer is not in any single link of the chain — it's in the entire supply chain itself.
Two decades of rapid urbanization in China built the world's largest and most complete building materials supply chain. From steel and insulated sandwich panels to door and window hardware and complete bathroom units, every component can be efficiently sourced within highly clustered industrial zones. As the domestic real estate market entered an adjustment phase, production capacity naturally shifted toward export markets.
9States is a typical example of this supply chain in action. Leveraging the Yangtze River Delta's building materials industrial base, 9States delivers end-to-end solutions covering design, module production, ocean freight logistics, and on-site installation guidance. The company has proven product configurations and delivery cases across seven major mining climate zones: Middle East dry heat, Siberian extreme cold, Southeast Asian tropical humidity, Andean high altitude, South American salt spray coast, Australian outback, and African savanna.
Against the backdrop of China's overall prefab building exports growing at 45% annually, the mining camp accommodation segment is expanding even faster. Mining companies worldwide are increasingly adopting modular camp solutions for their mine projects under development. This is driven not only by cost competitiveness — a standard dormitory module delivered and installed typically costs 40% to 60% less than local traditional construction — but also by the proven performance of modular products in reducing project timelines, ensuring consistent quality, and adapting to extreme environments, surpassing what conventional construction can deliver.
From a backyard cottage for an American couple to a thousand-bed camp for an African mine, China's prefab housing is penetrating every corner of the global market in different forms.
For mining companies, the math is straightforward: before a mine can start production, the fastest and most reliable way to house a workforce is not to wait years for local contractors — it's to place an order with a Chinese factory, and two months later, have a fully functional camp standing on the mine site.
Every day, the team at 9States participates in this mission — extending the factory production line to the world's most remote mining locations.
