Specifications and Models of Old Container Houses

The specifications and models of old container houses are primarily based on standard container dimensions and can be customized to meet diverse needs. Common specifications are as follows:

I. Standard Container Base Dimensions

The transformation of old container houses typically uses standard containers as prototypes, with core dimensions divided into three categories:

1. 20-foot Container: External dimensions are 6.06 meters in length × 2.44 meters in width × 2.59 meters in height, with an internal usable area of approximately 28.3 square meters. This specification is suitable for single occupants or small families and can also serve as independent functional modules (e.g., offices, storage rooms).
2. 40-foot Container: External dimensions are 12.2 meters in length × 2.44 meters in width × 2.59 meters in height, with an internal area of approximately 67.6 square meters. Its space can accommodate multiple occupants or be designed as a composite functional area (e.g., integrated living room, bedroom, and kitchen).
3. 40-foot High Cube Container: Based on the standard 40-foot container, the height is increased to 2.9 meters, providing a vertical space increase of approximately 12%. This specification is suitable for scenarios requiring increased ceiling height or mezzanine design, such as loft-style residences or commercial exhibition spaces.

II. Residential Customization and Expansion Dimensions

To meet residential comfort requirements, old container houses can achieve area expansion through container splicing or structural modifications:

1. Single Container Splicing: By horizontally or vertically splicing multiple containers, flexible spaces ranging from 30 to 120 square meters can be formed. For example, a combination of a 20-foot and a 40-foot container can achieve approximately 95 square meters (including common areas), while a double 40-foot container combination with a mezzanine design can reach 135 square meters.
2. Non-standard Width Customization: Some manufacturers offer width expansion services, increasing the standard width of 2.44 meters to 3-3.5 meters, enhancing internal horizontal space utilization.
3. Curved Roof Design: By transforming the container roof into a curved structure, headroom is increased, and lighting is improved, suitable for scenarios requiring higher ceiling heights (e.g., art studios, gyms).

III. Industry-Specific Functional Specifications

For specific needs, old container houses can be developed with special functional modules:

1. Foldable Container Houses: When unfolded, they can reach twice the size of a standard container, facilitating transportation and rapid deployment, suitable for temporary housing, post-disaster reconstruction, and other scenarios.
2. Sloped Roof Containers: With an eave height of 3.2 meters and a slope of 15-30 degrees, they enhance drainage performance and architectural aesthetics, commonly found in tourist attractions or rural homestays.
3. Emergency Medical Containers: Based on standard dimensions, an additional 0.5-meter equipment area is added, integrating negative pressure systems, air purification devices, etc., for use as mobile medical stations or epidemic isolation units.

IV. Technical Parameters and Performance Indicators

The transformation of old container houses must balance structural safety and residential comfort:

1. Load-bearing Capacity: The roof can bear 1-1.5 tons per square meter, and the floor can bear 3-5 tons per square meter, meeting the needs for furniture placement and personnel activities.
2. Thermal Insulation Performance: Using 50-150 mm polyurethane or PIR sandwich panels, with a thermal conductivity coefficient (K-value) of 0.18-0.28 W/m²K, adapting to different climatic regions.
