Oversized Combined Container House

An oversized combined container house is a type of housing formed by combining containers as basic modules through methods such as splicing, stacking, and expansion, featuring a relatively large spatial scale and composite functions. The following is an introduction from three aspects: application scenarios, structural characteristics, and advantages and challenges.

Application Scenarios

• Accommodation for Large-scale Events: For example, at the 2026 Nagoya Asian Games, the organizing committee used container houses to accommodate approximately 2,000 participants in order to reduce costs. The Chinese men's basketball team stayed in container-renovated houses at the port area dock, with three people sharing a room and using common bathroom facilities.
• Emergency Support and Temporary Relocation: In emergency rescue scenarios, foldable containers have become a popular choice for rapid transportation and accommodation due to their portability and low cost. For instance, foldable containers from different companies were transported from a factory in Suzhou to an emergency rescue site in Wuhu, Anhui, demonstrating advantages in transportation and storage costs.
• Commercial and Residential Integration: Some oversized combined container houses are not only used for living but also extend to commercial functions. For example, a huge black container building in a rural area is composed of 16 containers forming a four-story structure. In addition to serving as a family studio, it also has a café and event space that can be rented out for parties and exhibitions.

Structural Characteristics

• Modular Combination: Using standard containers as basic units, space is expanded through methods such as splicing, stacking, and offset stacking. For example, by splicing or offset stacking 2 - 3 containers, functional areas such as living rooms, bedrooms, and bathrooms can be created. Double-wing expansion containers fold in the side spaces during transportation and unfold the wings at the site to increase the usable area.
• Flexibility and Variability: Personalized designs can be carried out according to actual needs to achieve different functional layouts. For example, in a project in Chile, two sets of double-wing expansion containers were designed as two-bedroom, one-living-room, one-kitchen, and one-bathroom residential units, while the other two sets were designed as storage spaces.

Advantages and Challenges

• Advantages: Low cost and short construction period, enabling rapid deployment; flexible space utilization to meet diverse needs; modular design facilitating transportation and installation, suitable for different scenarios.
• Challenges: In severe weather conditions, problems such as house leakage and waterlogging may occur; living comfort may be affected, such as cramped space and limited bed sizes.
