Container House Design Flowchart

The core process of designing and constructing a container house can be divided into the following steps, as illustrated in the flowchart: land approval → container selection → structural modification → insulation and lighting design → interior decoration and system integration → exterior beautification → acceptance and maintenance.

1. Preliminary Planning and Approval

It is necessary to clarify the nature of the land (such as homestead or leased land), go through the house-building approval procedures, and provide structural drawings to avoid the risk of illegal construction. At the same time, determine the functional orientation according to needs, such as single-story or split-level layouts, and spatial divisions (living room, bedroom, bathroom, etc.). For example, a 100㎡ single-story layout can achieve an integrated living and dining area by connecting 2-3 containers.

2. Container Selection and Combination

Common specifications are 20 feet (with a load capacity of 25 tons) or 40 feet (with a load capacity of 45 tons), with side panels 1.6mm thick and roof panels 2.0mm thick. The splicing method should be combined with the terrain and function:

• Single-story combination: Suitable for small-area needs, forming a coherent space by horizontally connecting containers;
• Split-level stacking: The staggered layout of the upper and lower floors can create courtyards or aisles, improving ventilation and lighting, especially suitable for mountainous or forested areas.

3. Structural Modification and Reinforcement

When cutting containers, it is necessary to polish the cuts and apply epoxy primer + topcoat for rust prevention, and the welding points should be treated with special attention. For foundation construction, it is recommended to use pile foundations to elevate the containers, avoiding direct contact with the ground, preventing moisture and insects, and facilitating site leveling.

4. Insulation and Lighting Design

• Insulation treatment: The walls and roof need to be equipped with internal insulation layers, and triple-glazed windows (with better thermal insulation performance than red brick walls) should be selected; the roof should be designed with eaves or sunshades to reduce summer exposure.
• Lighting optimization: Install large floor-to-ceiling windows, roof skylights, or glass partitions to enhance natural light utilization.

5. Interior Decoration and System Integration

• Space utilization: Adopt designs such as folding beds and integrated cabinets to enhance the flexibility of small units;
• System installation: Integrate solar photovoltaic power generation systems to achieve energy self-sufficiency. In remote areas, rainwater collection systems and septic tank systems can be added.

6. Exterior Beautification and Acceptance and Maintenance

• Exterior treatment: Weaken the industrial feel through paint spraying, themed spray painting, cladding, or glass curtain walls;
• Maintenance points: Regularly inspect welds and corners for rust prevention (reapply anti-corrosion paint every 7-10 years in humid southern regions), replace sealants every 5-7 years, and clean roof leaves to prevent water accumulation.

Note: The actual design should be adjusted according to climate and terrain. For example, strengthen moisture-proof measures in humid areas and prioritize split-level designs in mountainous areas to improve ventilation.
