20-feet Container House
The 20-feet container house is an independent office or living unit transformed from a standard 20-foot container. It features a sturdy structure, convenient transportation, and strong expandability. Its common dimensions are 6×2.4×2.6 meters, and prices vary significantly depending on functions, materials, and configurations, ranging from several thousand to tens of thousands of yuan.

I. Basic Specifications and Structural Features
The 20-feet container house is transformed based on the international standard 20-foot container. Its external dimensions are typically 6 meters in length, 2.4 meters in width, and 2.6 meters in height, with a slight reduction in internal net dimensions due to wall thickness. Its core structure employs a high-strength steel frame, paired with color-coated steel plates, corrugated plates, or sandwich panels as wall and roof materials. It is windproof, earthquake-resistant, rainproof, and flame-retardant, with a service life of over 20 years. Some products optimize sound insulation and thermal insulation through air-gap thermal insulation designs, adapting to different climatic environments.
II. Functional Classifications and Expandability
- Basic Type: Used as a single unit, it can be planned as an office area, bedroom, or storage space, suitable for construction site command centers, temporary offices, etc.
- Expandable Type: By adding expansion modules (such as double-wing expansion boxes) on the sides or ends, the usable area can be increased by 30%-50%. For example, a 20-feet double-wing expansion box, when unfolded, has an indoor area of approximately 36 square meters, which can be designed as a two-bedroom, one-living room, one-kitchen, and one-bathroom residence or a multifunctional storage space.
- Modular Combination: Supports the connection of multiple units to form larger office or living areas, meeting the needs of temporary offices in industrial parks, event planning, etc.
III. Price Ranges and Influencing Factors
- Basic Container House: Priced at approximately 7,000-9,000 yuan, it is suitable for simple office or storage purposes, with color-coated steel plates as the main material and basic doors, windows, and lighting configurations.
- Expandable Container House: Priced at approximately 20,000-30,000 yuan, such as double-wing expansion boxes, it includes expansion structures, refined decoration, and functional zoning designs.
- High-end Customized Model: Priced at over 50,000 yuan, it employs weather-resistant steel, solar systems, or intelligent modular designs, suitable for long-term living or commercial use.
IV. Application Scenarios and Advantages
- Rapid Deployment: Prefabricated in factories, it has a short on-site installation period (usually completed within one day) and does not require foundation construction, making it suitable for emergency relief, temporary facilities on construction sites, etc.
- Convenient Transportation: It can be stacked and transported in a contracted state, reducing logistics costs, especially suitable for overseas projects (e.g., a Chilean project used two 40-feet containers to transport four sets of 20-feet double-wing expansion boxes).
- Flexibility and Sustainability: It is highly mobile and reusable; its materials are recyclable, aligning with green building trends.
