Container Modular Prefabricated Housing

Container modular prefabricated housing is a modular architectural form that uses containers as basic units and is assembled through combination and splicing.

Origin and Development

The concept of container modular prefabricated housing was proposed by Phillip C. Clark in 1987 with a modification patent. Modular integrated housing originated in the United States in the early 20th century and was initially used for temporary buildings. With technological progress, its applications have expanded to multiple fields. In 2006, the first double-story container residence certified by the state appeared in the United States. In 2008, CIMC built a container school in Wenchuan after the earthquake that could accommodate a thousand people. In 2010, China initiated the compilation of relevant technical regulations. In 2012, CIMC created the world's first recyclable container hotel for the United Kingdom. In 2020, the first integrated housing production line was put into operation in Gansu. In 2026, Guangzhou City introduced measures to promote the development of modular buildings, and the Canton Fair set up a special zone for 'integrated housing and courtyard facilities' for the first time.

Structure and Materials

It adopts a steel frame structure, with corrosion-resistant steel plates and environmentally friendly panels as the core materials. Combined with ship anti-corrosion technology, its service life can reach more than 20 years, and it supports customized design in standard sizes ranging from 20 to 60 feet.

Construction Characteristics

• Rapid Construction: The main structure, interior decoration, and equipment pipelines are prefabricated in the factory and then transported to the site for assembly like 'building blocks', which can shorten the construction period by more than 50%. For example, for the MRDC modular hotel in Papua New Guinea, traditional construction would take 14 to 18 months, while the modular solution only takes about 7 months in total.
• Low Cost: The short on-site construction period reduces the constraints of labor, and the quality is standardized. Significant savings in labor costs are achieved. For hotels of the same scale, the number of on-site permanent staff in modular construction is much less than that in traditional cast-in-place construction, and the shortened construction period reduces hidden costs. Lightweight steel structure modules reduce the consumption of foundation and main structure materials, reducing the use of ground materials by 60 - 70%. The material waste from standardized CNC cutting in the factory is only 3% - 5%, while that on traditional construction sites is 8% - 12%.
• Green and Environmentally Friendly: There is less construction waste, the quality is controllable, and it can be flexibly disassembled and recycled.

Application Areas

It is widely used in residential, office, emergency, temporary resettlement, tourist homestays, commercial pop-ups, overseas engineering camps, and permanent residential, school, hospital, hotel, data center, and livelihood projects in Pacific island countries. During the COVID-19 pandemic, it was used to build makeshift hospitals and quarantine sites.

Technological Iteration

New systems such as MiC, C-MiC, and SMC have emerged, transferring more than 90% of the construction processes to the factory, which helps shorten the construction period, reduce construction waste and carbon emissions, and improve building quality and recyclability.

Market Situation

In the first quarter of 2026, the export growth rate of prefabricated buildings (including modular buildings) in China reached as high as 45%. In the first four months alone, the export of 'mobile houses' through the Shenzhen port reached 1.68 billion yuan, a year-on-year increase of 19.6%, with products shipped to more than 150 countries and regions.
