45-meter Container House

The 45-meter container house is typically transformed from a 45-foot container. Despite its compact interior space, it can meet living needs through reasonable design and features environmental friendliness, flexibility, and mobility, but attention must be paid to fire safety.

I. Structure and Space Design
The 45-meter container house is generally composed of a set of 40-foot and a set of 20-foot containers, arranged in an L-shaped staggered layout and stabilized with deep piles. For example, in a case in Auckland, New Zealand, the main body of the house is placed on high ground to optimize the view and lighting, with a wooden deck extending behind as a resting space. The interior space is utilized extremely compactly: the main container includes a living room, kitchen, bedroom, and bathroom, while the smaller container is transformed into an office and guest room. The functional design emphasizes versatility, such as hidden storage cabinets under corner sofas that can be unfolded into double beds, office desks that can be folded into beds, and pull-down folding beds on the walls, accommodating up to seven people simultaneously.

II. Material and Performance Advantages
The container house uses steel containers as its main structural component, featuring durability, ease of movement, and reusability. Second-hand 45-foot containers have lower costs, long service lives, and significantly lower prices compared to temporary简易 houses (simplified houses). Its environmental friendliness is reflected in the recyclability of materials, and some cases have passed the '8 Homestar' certification, achieving comprehensive sustainability standards in energy utilization, water efficiency, and material environmental friendliness.

III. Fire Safety Hazards and Prevention
Container houses have certain fire risks that require attention:

1. Material Hazards: Some temporary houses use flammable sandwich materials such as polystyrene and polyurethane foam to save costs, which have poor fire resistance and can be ignited by electrical welding sparks or cigarette butts.
2. Combustion Characteristics: Flammable materials burn rapidly, melting and deforming at 80℃, causing fire to spread, and their combustion products are highly toxic.
3. Rescue Difficulties: The spread of fire can easily lead to collapse, and the iron sheet wrapping structure hinders water gun spraying, increasing the difficulty of firefighting.
4. Escape Difficulties: Black smoke is produced during combustion, and toxic smoke accumulates, making it difficult for trapped individuals to survive.
   Preventive Measures: Use A-grade fire-resistant materials such as rock wool boards and fireproof cotton for filling; keep heat sources and fire sources away from the house; protect wires with sleeves, use metal galvanized boxes, and install them openly; equip with simple firefighting equipment; and maintain a house spacing of more than 6 meters.
