China’s Prefab Housing Boom: Factory-Built Homes Surge

China’s prefabricated housing industry is experiencing an unprecedented surge in orders as the country’s construction sector undergoes a fundamental transformation from on-site building to factory-based manufacturing. The shift is reshaping how homes, hospitals, hotels, and even data centers are conceived, produced, and delivered—both domestically and across global markets.

According to Xinhua News, the transformation represents a paradigm shift in China’s construction industry, moving the bulk of building work from dusty construction sites into controlled factory environments where robots weld, assemble, and finish building modules with millimeter-level precision.

From Construction Site to Factory Floor

At China Construction Steel Structure’s smart factory in Huizhou, Guangdong Province, a 400-meter automated production line—the first steel structure modular intelligent production line in China—operates around the clock. Robots handle welding, assembly, and surface finishing, while automated guided vehicles (AGVs) shuttle materials across the factory floor.

“Guess how many this production line can produce in a day? 50! North American factories of the same type produce 5 a day. We are 10 times that,” said Li Huakun, chief engineer at China Construction Steel Structure Green Technology Co., Ltd., as reported by Xinhua.

The precision is equally remarkable. “Previously, construction precision was at centimeter level or several millimeters. Now in digital workshops, precision can be controlled to 1-2 millimeters,” Li added.

Meanwhile, at China Construction Hailong’s intelligent manufacturing industrial park in Shenzhen’s Longgang district, a four-story, 50-meter-tall vertical factory houses the world’s first concrete MiC (Modular Integrated Construction) flexible intelligent manufacturing line. “A fully-equipped module comes off the line every 20 minutes,” said Wang Qiong, chief engineer at China Construction Hailong Technology Co., Ltd. The facility’s annual delivery capacity ranges from 20,000 to 30,000 concrete prefabricated modules.

Explosive Export Growth

The scale of this industrial shift is reflected in export data. According to 21st Century Business Herald, citing China’s General Administration of Customs, China’s prefabricated building exports grew from $1.472 billion in 2015 to approximately $4.339 billion in 2025—nearly tripling in a decade. In the first quarter of 2026 alone, exports grew approximately 45 percent year-over-year.

Shenzhen port has emerged as a key export hub. In the first four months of 2026, companies exported 1.68 billion yuan worth of mobile and prefabricated houses through the port, up 19.6 percent year-over-year and accounting for 13.8 percent of China’s total exports of such products. These exports reached more than 150 countries and regions, according to The Cover, which reported on CCTV Finance data.

Global Success Stories

The international appeal of Chinese modular construction is demonstrated by projects spanning multiple continents. In the United Kingdom, a property developer purchased 63 modules of Chinese-made modular retirement apartments. The modules were shipped to Southampton and assembled on site in just two weeks. British developer Paul Sorki explained the decision: “In the UK, land and traditional construction costs have become very expensive over the past few years. We looked at solutions from other countries, but ultimately chose China because no one could match the price.”

In Papua New Guinea, 84 modules shipped from China were assembled into a fully functional hotel. The country’s prime minister personally signed for the delivered modular building products in May 2026. The developer has since placed multiple follow-up orders, with a fifth phase currently under discussion.

“From the year before last to now, we have delivered nearly 20,000 such modules. These two years have seen explosive growth, and the technology is gradually maturing,” said Leng Hanyu, manager of technology and design management at China Construction Steel Structure Green Technology Co., Ltd. “There is demand abroad and production capacity at home. On-site, only about 10% of the work remains—just handling common areas.”

Breaking Into New Markets

China’s modular construction industry is also breaking new ground in regulatory terms. In 2025, China Construction Hailong obtained the first MiC principle pre-approval permit from Dubai Municipality—the first for any Chinese company. The seven-month approval process involved adapting to American standards and Dubai’s building codes, marking a shift from Chinese companies simply meeting international standards to actively shaping them.

Domestically, modular construction is gaining policy support. In March 2026, Guangzhou’s Housing and Urban-Rural Development Bureau issued measures requiring modular buildings to account for no less than 15 percent of floor area in new resettlement housing and no less than 10 percent in new commercial housing land parcels, as reported by Viewpoint/Ifeng.

Shenzhen’s modular building implementation area now exceeds 1.6 million square meters. The Shenzhen People’s Hospital Bao’an branch—a six-floor, 200-bed facility with 101 ward modules and 168 electromechanical modules—was fully assembled on site in just 12 days.

The Economics of Modular Construction

Modular construction offers compelling economic advantages. “The cost is in manufacturing and shipping; the savings are in labor,” Li Huakun explained. In Australia, where traditional construction labor costs account for 30 to 40 percent of total project costs, modular construction reduces on-site labor by more than half and shortens construction timelines by more than 60 percent. “Overall construction costs reduced by more than 10%!” Li said.

A hospital that would normally take three years to build using conventional methods can be completed in one year and eight months with modular technology, according to project manager Shen Zhaoyuan. During hoisting, workers achieved one floor every two days.

Industry Outlook and Challenges

Market research institutions project the global modular building market will exceed $142.8 billion by 2030, according to People’s Daily. China is also contributing to international standards—the country submitted the first international standard for digital product passports in the construction industry, which was approved for project initiation at ISO.

However, the industry faces significant challenges. “Modular construction is standardized, digital work that requires a large number of digital-intelligent talents,” said Jiang Li, deputy general manager of China Construction Steel Structure. The industry faces a shortage of three types of composite talent: designers familiar with overseas standards, production line engineers who understand manufacturing processes, and on-site delivery personnel with both technical knowledge and foreign language skills.

Li Huakun also offered a note of caution: “Modularization is not a panacea. But no building system in the world can solve everything. Find the right scenario, play to strengths—the modular, prefab market is huge.”

What to Watch For

As China’s prefabricated housing industry continues its explosive growth, several developments bear watching: the expansion of domestic policy support beyond Guangzhou, the pace of international standard-setting by Chinese firms, and whether the talent pipeline can keep pace with industrial expansion. With global demand for faster, more cost-effective construction methods rising, China’s modular building industry appears positioned to play an increasingly central role in how the world builds.

“Modular construction is the new quality productive force of the construction industry,” Wang Qiong said. The first step—industrialized production and data-driven process management—has been achieved. The next challenge is ensuring China’s modular building technology becomes a major force in the global construction industry’s industrialization transformation.
