Dimensions of Container Houses in Gannan

The common dimensions of container houses in the Gannan region are based on standard container specifications, combined with customized non-standard requirements, and can be categorized as follows:

1. Standard Container Sizes

• 20-foot Container: External dimensions are 6.06 meters in length, 2.44 meters in width, and 2.59 meters in height (standard high cube) or 2.89 meters (high cube), with an internal volume of approximately 33 cubic meters. This size is suitable for single occupants or small families, offering compact yet fully functional living space.
• 40-foot Container: External dimensions are 12.19 meters in length, 2.44 meters in width, and heights of 2.59 meters and 2.89 meters, with an internal volume of approximately 67 cubic meters. It is suitable for multiple occupants or scenarios requiring partitioned functions, such as combined office and living spaces.

2. Other Common Specifications

• 20-foot Container: Internal dimensions are 5.69 meters in length, 2.13 meters in width, and 2.18 meters in height, with a volume of 24-26 cubic meters. This specification is more flexible for transportation and installation but has relatively limited internal space.
• 40-foot Container: Internal dimensions are 11.8 meters in length, 2.13 meters in width, and 2.18 meters in height, with a volume of 54 cubic meters. It offers high space utilization and is suitable for medium-sized families or small teams.
• 40-foot High Cube Container: Internal dimensions are 11.8 meters in length, 2.13 meters in width, and 2.72 meters in height, with a volume of 68 cubic meters. It increases vertical space by adding height, suitable for scenarios requiring storage or tiered design.
• 45-foot High Cube Container: Internal dimensions are 13.58 meters in length, 2.34 meters in width, and 2.71 meters in height, with a volume of 86 cubic meters. This specification offers spacious space but requires consideration of transportation and installation feasibility, typically used for large-scale projects or special needs.

3. Customized Non-Standard Adjustments

• Width Expansion: Some manufacturers offer widened designs, such as 2.5 meters or 3 meters in width, but the total width must not exceed domestic road width limits (generally 4.5 meters), otherwise special transportation permits are required.
• Height Expansion: Vertical space can be expanded by increasing the height of the container or stacking two layers, but structural stability must be evaluated to avoid safety hazards caused by excessive loads.
• Notes: Non-standard dimensions may increase costs by 10%-30% and require approval from local building codes. When actually living, the thickness of wall insulation (approximately 10-15 centimeters) should be deducted, and the usable internal space will be slightly smaller than the nominal dimensions.

Selection Advice: Users in the Gannan region should comprehensively determine dimensions based on transportation conditions, usage needs, and manufacturer availability. For temporary living or small projects, standard 20-foot or 40-foot containers offer higher cost-effectiveness; for long-term living or special functions, customized non-standard or high cube specifications can be considered.
