Container House Size Illustration

The following are the common standard sizes and combination methods of container houses. When in actual use, it is necessary to reserve 10% of the space and maintain structural integrity:

I. Standard Container Sizes

1. 20-foot General Purpose Container: It has an internal length of 5.9 meters, a width of 2.3 meters, a nominal capacity of 33 cubic meters, and an actual available capacity of about 28 cubic meters. This size is suitable for single-person living or small office scenarios, with compact space but complete functions.
2. 40-foot Container: It has a capacity of 58 cubic meters, which is larger than the combined space of two 20-foot containers. The high-cube version can reach a height of 2.7 meters (including the air-conditioning position), increasing the utilization rate of vertical space and being suitable for designs that require higher ceiling heights.
3. 45-foot Container: It has a capacity of 86 cubic meters and an open internal space, suitable for large open-plan designs such as open office areas or public activity spaces. Reducing partitions can enhance the sense of spatial openness.

II. Splicing and Combination Examples
Modular splicing can break through the size limitations of a single container. For example, Guangzhou Jinge Company uses three 40-foot containers to splice into a duplex structure measuring 11.8 meters × 6.75 meters × 2.8 meters, with an available area of 80 square meters. Such designs require prior planning of water and electricity lines and load-bearing structures to ensure stability after splicing.

III. Custom Sizes and Processing Limitations
Manufacturers can produce non-standard sizes according to needs, such as small single rooms measuring 3 meters on each side or suites measuring 6 meters × 3 meters. However, it should be noted that:

• Equipment Processing Limitations: Cutting the container body may damage the original structural strength. Self-modification can easily lead to collapse risks and should be carried out by professional manufacturers.
• Space Reservation Principle: In actual use, 10% of the space should be reserved for equipment installation, ventilation, and personnel activities to avoid overcrowding.
• Structural Integrity: During modification, the container frame should remain unchanged. Functions can be optimized by adding internal partitions or extending the ceiling height, but major load-bearing components should not be removed.

IV. Application Scenario Recommendations

• Residential Scenarios: 20-foot or 40-foot containers are suitable for single-person/family living, while 45-foot or spliced structures can meet the needs of multiple people living together.
• Commercial Scenarios: Custom suites or duplex structures are suitable for offices, cafes, etc., and need to be combined with sound insulation and lighting design.
• Temporary Facilities: Standard containers have obvious advantages in rapid deployment, but long-term use requires consideration of anti-corrosion and moisture-proof treatments.

Summary: The selection of container house sizes should take into account both functional requirements and structural safety. Standard sizes offer high flexibility, splicing and combination can expand the space, and customization should strictly follow processing specifications.
