Longnan Container House Design

The design of container houses in Longnan requires comprehensive consideration of multiple factors, including functionality, structure, safety, aesthetics, and sustainability. The following analysis is conducted from three dimensions: design key points, case references, and technical specifications.

I. Core Design Key Points

1. Functional Zoning
   It is necessary to clarify the purpose of the house (such as residential, office, or commercial use) and plan the space reasonably. For example, residential container houses should be equipped with separate bedrooms, kitchens, and bathrooms, ensuring an indoor clear height of ≥2.4 meters and a local clear height of ≥2.1 meters (referencing rural dilapidated house renovation standards). Commercial houses should focus on openness and circulation design. For instance, the reception center of Aolunda Tribe in Shanghai expands the actual usable area and enhances spatial hierarchy by staggering and combining containers and introducing the concept of 'shadow'.

2. Structural Safety
   Container houses must meet load-bearing requirements. Priority should be given to using GB/T12418-inspected and qualified containers, ensuring that beams and columns are free from defects and corner fittings are intact. The structural load path should be 'panel secondary beam → main beam → corner column → corner fitting → foundation'. Corner fittings are the only stacking load-transfer points, and spot welding is prohibited as a substitute. When stacking multiple containers, corner fittings and corner columns must be aligned and locked vertically. The seismic fortification intensity should be ≤8 degrees, with a maximum of 6 stories and a height of ≤24 meters.

3. Lighting and Ventilation
   Natural lighting can be optimized by adding windows, skylights, or using transparent panel materials, while ventilation can be ensured by designing air vents or mechanical ventilation systems. For example, the 'Container House' in São Paulo creates a bright space with a white color scheme and uses visual illusions to enhance the sense of space.

II. Case References

1. 'Container House' in São Paulo
   Composed of two 40-foot containers placed side by side, it integrates a living room, kitchen, and bedroom suite. The floor and facade are finished with ultra-dense decorative materials, and it is equipped with a 90-square-meter outdoor space, reflecting a combination of minimalism and functionality.

2. Reception Center of Aolunda Tribe in Shanghai
   Composed of ten staggered containers, it expands the usable area by introducing the concept of 'shadow', breaking the traditional industrial impression and achieving integration with the natural environment.

III. Technical Specifications and Material Selection

1. Fire Prevention and Corrosion Resistance
   The use of flammable core materials such as EPS in enclosure fillings is prohibited. For crowded places, Class A rock wool/glass wool with a fire resistance limit of ≥0.5 hours should be used. Steel structures should be coated with fire-resistant paint and equipped with escape routes (with a clear width of ≥0.9 meters), fire extinguishers, and other facilities.

2. Material and Mobility
   Steel containers are the most commonly used, while aluminum containers are lighter but more expensive. Composite sandwich panel containers are suitable for temporary buildings. Depending on the needs, fixed (hoisted), towed mobile, or folding and transportable types can be selected.

3. Sustainability
   Priority should be given to using recyclable materials, such as the 100% recyclability achieved in the São Paulo case. Additionally, energy-saving technologies (such as solar panels and rainwater collection systems) can be adopted to reduce environmental impact.
