House Container

House containers typically refer to container-style housing units in modular construction, which achieve rapid construction through factory prefabrication and on-site assembly, featuring standardization, mobility, environmental friendliness, and efficiency.

Modular Construction Approach

The core of house containers lies in modular construction technology, which divides an entire building into independent modules (such as bathrooms, living rooms, and bedrooms). Over 80% of the processes, including the main structure, interior decoration, plumbing and electrical systems, and sanitary facilities, are completed on factory assembly lines before being transported to the site for assembly. For example, China State Construction Integrated Architecture built modular houses for Australia, with each module integrating plumbing, electrical systems, decoration, and even soft furnishings, allowing for “move-in ready” occupancy upon connecting to utilities on-site. China State Construction Steel Structure Jiangsu Co., Ltd. produced “building block houses” for the North American market, which were transported across the ocean in containers as four independent modules and directly assembled into fully furnished residences on-site.

Technical Characteristics and Advantages

1. High Construction Efficiency: Factory prefabrication and on-site assembly operate in parallel, shortening the construction period by 60%-70% compared to traditional methods. For instance, an 18-story high-rise residential project in Hong Kong, which would take 3-5 years to build traditionally, was delivered in just one year using a modular approach.
2. Environmental Friendliness and Low Carbon Emissions: On-site assembly reduces noise, dust, and construction waste, meeting the stringent green construction requirements of markets such as North America and Europe. For example, China State Construction Steel Structure's North American project reduced carbon emissions during the construction phase by approximately 40% through factory operations.
3. Quality Control: Standardized production in factories ensures manufacturing precision within 1-2 millimeters, significantly improving product quality over on-site wet construction. For example, a smart factory in Guangdong can produce 50 modules per day, ten times the capacity of similar factories in North America.
4. Flexibility and Relocatability: Steel-structured modular houses feature a steel frame paired with fire-resistant rock wool sandwich panels as the main structure, integrating insulation, fire protection, sound insulation, and waterproofing. They can be repeatedly disassembled and relocated. For example, a company in Hohhot specializing in residential container houses uses a combination of galvanized steel frames and rock wool sandwich panels, with single-lift transportation costs ranging from 15 to 25 yuan per kilometer, resulting in low relocation and resettlement costs.

Application Scenarios and Market

House containers have been widely used in temporary housing, commercial buildings, data centers, and other fields. In the first four months of 2026, enterprises across the country exported movable houses worth 1.68 billion yuan through Shenzhen ports, a year-on-year increase of 19.6%, with products sold to over 150 countries and regions. Their cost-effectiveness is remarkable: the average construction cost for houses of the same specifications in the United States is approximately 165 USD per square foot, while the total landed cost of Chinese modular houses is less than 30,000 USD (for a two-bedroom, one-living-room unit of about 70 square meters), with an installation period of just a few days.
