How to Convert a Container into a House

Converting a container into a house requires scientific design and standardized construction to achieve functionality and safety. The specific steps are as follows:

1. Foundation Design and Structural Adjustment
Select the container type based on site conditions (e.g., standard sizes of 20-60 feet), prioritizing recycled shipping containers to reduce costs. To expand space, arrange multiple containers at a certain distance apart and build connecting frames with wood or steel in between to form an open or semi-open structure. For example, the 'Floating House' project elevates containers with metal columns, reducing concrete usage while preserving the original landscape and enhancing earthquake resistance. If the site is uneven, pour concrete foundations in advance or use adjustable supports to ensure the containers are level.

2. Frame Reinforcement and Space Division
Although the original structure of the container is strong, local reinforcement is needed after cutting windows or doors. Assemble wooden or steel frames on both sides of the container, secure them to the container skeleton with bolts, and build triangular trusses at the top gaps to support the roof. Lay moisture-proof treated wood or composite flooring on the ground and reserve channels for pipelines. For window and door installation, cut the container walls in advance, embed metal frames, and seal with waterproof glue to prevent rain leakage.

3. Roof and Waterproofing Treatment
The container roof requires layered treatment: first, lay oriented strand board (OSB) as the base layer, cover it with waterproof tarpaulin or asphalt felt, then fix wooden strips to form a drainage slope, and finally install aluminum panels, color-coated steel sheets, or tiles. If the original container roof is retained, build a frame simultaneously and cover it with waterproof materials to ensure overall sealing. The eaves should be extended by at least 30 centimeters to prevent rainwater from flowing back onto the walls.

4. Material Selection and Eco-Friendly Design
Prioritize the use of recycled materials: salvaged wood can be used for interior decoration, and the remaining steel plates from container cutting can be processed into furniture or decorative pieces. For example, the 'Floating House' enhances sustainability through roof greening (planting drought-resistant plants) and a rainwater harvesting system (collecting rainwater for irrigation), with 70% of construction waste being reused. The exterior walls can be painted with eco-friendly coatings to reduce volatile organic compound (VOC) emissions.

5. Detail Refinement and Safety Measures
Strictly follow the design drawings during construction, reserving enough windows (with an area not less than 10% of the indoor floor area) to ensure ventilation and prevent moisture-induced steel plate corrosion. The edges of windows and doors should be polished smoothly and painted with anti-rust paint, with gaps filled with silicone. For long-term residence, treat the steel plates with ship anti-corrosion processes (such as spraying epoxy zinc-rich primer) to extend their service life. The electrical system should be wired independently and equipped with leakage protection devices, and gas pipelines should comply with national regulations.

6. Compliance and Customization
Before renovation, confirm local building regulations, as some areas require container houses to pass structural safety inspections and obtain temporary building permits. Refer to the 'Technical Specification for Modular Combined Container Houses' for standardized design, such as stipulating that the distance between containers should be no less than 1.5 meters to ensure fire lanes. Customize functional modules according to needs, such as adding solar panels, ground-source heat pumps, and other energy-saving devices, or designing movable structures for easy relocation.
