Ningbo Container House Size Diagram

Common sizes of container houses in Ningbo include standard container sizes, customized sizes, and sizes derived from shipping containers, with specific specifications as follows:

I. Standard Container House Sizes
The fast-assembly container houses produced by Ningbo Zhiya Integrated Housing Co., Ltd. adopt a specification of 6 meters in length, 3 meters in width, and 2.8 meters in height, which is a commonly used size for on-site accommodation, offices, medical and epidemic prevention, and other scenarios. Its internal net space is optimized through modular design, meeting basic living needs, and supporting color customization and free design drawing services. In international standards, 20-foot dry cargo containers (with an inner dimension of 5898×2352×2390 millimeters) and 40-foot dry cargo containers (with an inner dimension of 12024×2352×2390 millimeters) are also often transformed into houses. However, it should be noted that their original design is for maritime transportation, with a relatively low indoor height (about 2.39 meters) and a long and narrow horizontal space, requiring container combination to improve the spatial layout.

II. Customized Container House Sizes
The Ningbo market offers a variety of customization services, with sizes including but not limited to 3 meters × 3 meters, 3 meters × 8 meters, 3 meters × 9 meters, etc., mainly designed according to customer needs. For example, a small single-container building may adopt a 3-meter × 3-meter specification, while a large combined building can achieve an area of hundreds of square meters by splicing dozens of containers. Customized sizes need to consider transportation restrictions (such as road width and bridge height) and structural stability, and usually require evaluation by professional manufacturers before production.

III. Sizes Derived from Shipping Containers
The specifications of shipping containers are of great reference value for house design. Common types include:

• 20-foot open-top container: with an inner dimension of 5890×2320×2310 millimeters, the top can be opened, suitable for scenarios requiring vertical lifting equipment;
• 40-foot high cube container: with an inner dimension of 12024×2352×2698 millimeters, the height is increased to 2.698 meters, improving living comfort;
• 45-foot high cube container: with an inner dimension of 13580×2340×2680 millimeters, providing a larger volume, but it is necessary to confirm whether local transportation regulations allow oversized containers.

Precautions:

1. The size of the container house should be selected according to functional requirements. For example, dormitory buildings need to consider the per capita area, and hotels need to plan corridors and restrooms;
2. Customized sizes may involve additional costs, and it is necessary to confirm the process feasibility with the manufacturer;
3. When used in combination, the structural load-bearing capacity needs to be calculated. In international standards, a 20-foot container has a load-bearing capacity of about 25 tons, and a 40-foot container has a load-bearing capacity of about 45 tons.
