How to Combine Container Houses

There are various ways to combine container houses, and you can choose single-container or multi-container combinations according to your needs, achieving different functions and spatial effects through horizontal splicing, vertical stacking, offset/cantilevering, etc.

Single-Container Combination

As a basic unit, a single container can enhance space utilization through internal modular layout. For example, functional areas can be divided along the length, with modules for living, sleeping, and storage set up to meet residential, office, or commercial needs. Deformation expansion is a feature of single containers, such as folding down the container panels to form a patio or using hydraulic rods to flip up and build an awning, increasing the usable area. Telescopic expansion is achieved through movable side panels and pulley designs, allowing the container to slide out internal modules upon arrival at the destination, doubling the space. In addition, single containers can be creatively shaped through cutting and reassembly, such as dividing a 40-foot container into two parts and connecting the gaps with a roof to form a split modular building, paired with large windows and an open patio to enhance indoor-outdoor interaction.

Multi-Container Combination

For multi-container combinations, it is crucial to consider the position and connection method of the containers. Horizontal splicing is suitable for expanding planar space, such as打通 (connecting) two containers horizontally to form a flat layout with an integrated living and dining area, two bedrooms, and a bathroom, covering an area of up to 100 square meters. Vertical stacking uses corner fittings to transfer loads vertically, enabling the construction of buildings up to six stories high, such as dormitories or hotels. It is essential to ensure that the corner fittings and corner columns are aligned and locked tightly vertically to maintain structural stability. Offset/cantilever combinations can create rich spatial layers, such as L-shaped or U-shaped enclosed layouts, often used in trendy homestays, cafes, and other settings. However, the cantilevered sections require additional diagonal bracing and prohibit drilling to maintain structural safety. Additionally, crisscross stacking can create large buildings, such as a four-story structure composed of 16 containers, achieving flexible spatial scales through standardized modules.

Combination Principles and Considerations

When combining containers, it is necessary to follow the logic of structural loading to ensure a clear load transfer path. For example, welded containers transfer roof loads to the sill through sidewall columns and then distribute them evenly to the ground, suitable for frequent relocation. Bolted modular containers require checking the tightness of connection nodes to avoid affecting overall stability. At the same time, fire prevention and corrosion resistance requirements must be considered. Class A rock wool or glass wool should be used for filling in crowded places, steel structures should be coated with fire-resistant paint, and escape routes and fire extinguishing equipment should be provided.
