Second-hand Container House Capacity
The capacity of second-hand container houses varies depending on the specific model and design, with common specifications ranging from 33.2 cubic meters to 86 cubic meters. Here is an explanation of the capacities of different types of second-hand container houses:

Standard second-hand container houses are typically modified from international standard containers. Their external dimensions are 3000mm (length) × 6000mm (width) × 2720mm (height), with an internal usable space of 2860mm × 5860mm × 2500mm, reaching a capacity of up to 45 cubic meters. This type of container house, by optimizing its internal structure, can meet basic living or office needs and is suitable for temporary buildings, construction site dormitories, and other scenarios.
The capacities of other common second-hand container specifications are as follows:
- 20GP Second-hand Container: With a length of 6.05 meters, width of 2.43 meters, and height of 2.59 meters, it has a capacity of 33.2 cubic meters. This specification has a relatively small volume and is often used in scenarios with lower transportation or storage requirements. When converted into a house, it is suitable for single occupancy or small functional rooms.
- 40GP Second-hand Container: With a length of 12.19 meters, width of 2.43 meters, and height of 2.59 meters, it has a capacity of 67.7 cubic meters. Its length is doubled, significantly increasing the internal space. It can be converted into a two-bedroom or multi-functional office area, suitable for family living or use by small to medium-sized teams.
- 40HQ Second-hand Container: With a length of 12.19 meters, width of 2.43 meters, and height of 2.89 meters, it has a capacity of 76.3 cubic meters. Compared to the 40GP, its height is increased by 0.3 meters, providing more vertical space. It is suitable for scenarios requiring higher ceilings, such as conversion into houses with lofts or art studios.
- 45HQ Second-hand Container: With a length of 13.71 meters, width of 2.43 meters, and height of 2.89 meters, it has a capacity of 86 cubic meters. As the largest specification of second-hand containers, both its length and capacity reach their peak, meeting the needs of large event spaces, warehousing, or commercial purposes.
It should be noted that the actual capacity may vary slightly due to the modification design of the container house (such as partitions, door and window positions, and the thickness of interior decoration). When choosing, a comprehensive assessment should be made based on the specific purpose, site constraints, and budget.
