Container House Interior Decoration Standards

The interior decoration of container houses should be standardized according to their intended use and meet general safety and functional requirements. The specific standards are as follows:

I. Classification-Based Decoration Standards

1. Dormitory Type (20-foot container)

   • Space Allocation: Designed for 4-6 people, with a per capita area of ≥2.5㎡ to avoid overcrowding.
   • Furniture Configuration: Use bunk beds to save space, and provide storage cabinets for personal belongings. Independent bathrooms should be waterproofed and equipped with ventilation fans to prevent moisture and odor buildup.
   • Safety Restrictions: Prohibit the use of high-power electrical appliances such as induction cookers and electric heaters to reduce fire risks.

2. Office Type (40-foot container)

   • Functional Zoning: Divide into an office area (for 10-15 people), a reception area, and a pantry. Reserve space for filing cabinets to ensure efficient office workflow.
   • Lighting Requirements: The area of lighting windows should be ≥1/5 of the wall area to ensure sufficient natural light and reduce reliance on artificial lighting.

3. Homestay Type (Modular Combination)

   • Space Layout: Design with 1-2 bedrooms, a living room, and a bathroom, equipped with an independent kitchen (which should be fire-resistant). Meet both living and cooking needs.
   • Bathroom Design: Adopt a wet-dry separation structure with ventilation rates of ≥3 times per hour to prevent moisture and bacteria growth.

II. General Standards

1. Space Dimensions: The indoor clear height should be ≥2.4m, and the aisle width should be ≥0.9m to ensure unobstructed movement.
2. Fire Safety: The fire compartment area should be ≤500㎡, and firewalls should be installed if exceeded. Except for homestays, kitchens are prohibited indoors, and high-power electrical appliances are banned in dormitories.
3. Ventilation and Lighting: The area of natural ventilation windows should be ≥10% of the indoor area. Mechanical ventilation equipment should be installed in areas without natural ventilation. The indoor illuminance should be ≥100lx to avoid dark corners affecting usability.

III. Key Considerations

• Material Selection: Use waterproof and fire-resistant materials in kitchens, bathrooms, and other areas to extend service life and reduce safety hazards.
• Electrical Management: Clearly define electrical appliance usage restrictions in dormitory-type houses and reasonably plan electrical circuits in office-type houses to avoid overloading.
• Ventilation Maintenance: Regularly clean mechanical ventilation equipment to ensure air exchange efficiency. Natural ventilation windows should be kept easily operable.

By combining classified design with general standards, container houses can balance practicality, safety, and compliance to meet the needs of different scenarios.
