Extended Container House Drawings

The drawings for extended container houses need to be designed in combination with functional requirements, spatial planning, and structural safety. Here are the key points and case references:

I. Basic Structure and Size Planning

Container houses use standard 20-foot (6 meters long, 2.4 meters wide, and 2.6 meters high) or 40-foot (12 meters long, 2.4 meters wide, and 2.6 meters high) containers as modules, expanding the space through horizontal or vertical splicing. For example:

• Single-container renovation: A 15㎡ forest home utilizes a single 20-foot container, enhancing functionality by adding front and back doors, a patio, and solar panels on the roof.
• Multi-container combination: A Melbourne villa uses three containers stacked in a staggered manner to form a double-story space; a Danish 9-container residence creates patios and light wells through an interlaced layout.
• Space expansion techniques: Cut the sides or top of the container to embed glass curtain walls or balconies; use the gaps between containers to design walkways or green areas.

II. Functional Zoning and Interior Design

Divide core areas according to needs, focusing on space utilization and smooth traffic flow:

• Living area: Use custom folding beds and sofa beds to achieve multi-functionality; combine the bedroom background wall with open storage to reduce partitions and enhance transparency.
• Kitchen and bathroom area: A linear kitchen saves space, with upper and lower cabinets increasing storage; the bathroom adopts rounded corners and a wet-dry separation design to improve practicality.
• Public area: The living room integrates leisure, reading, and dining functions, with flexible layout adjustments through foldable tables and chairs.
• Case reference: A 15㎡ container home in Jiangsu achieves full functionality covering the living room, bedroom, kitchen, and bathroom through integrated design; a 30㎡ villa for two sisters adds an open-air balcony and a leisure area.

III. Structural Reinforcement and Safety Regulations

• Load-bearing and stability: Use galvanized steel frames instead of single-layer iron sheets, paired with intermediate beams and columns to enhance load-bearing capacity; use high-strength bolts at container connections to ensure earthquake resistance.
• Thermal insulation and sound insulation: The walls use sandwich thermal insulation panels (such as polyurethane foam), with thermal insulation layers added on the roof; doors and windows use double-layer laminated glass to reduce noise and temperature differences.
• Fire prevention and ventilation: Use fire-resistant materials for wall decoration, add ventilation openings or mechanical ventilation systems; equip the kitchen and bedroom with smoke alarms.

IV. Sustainable and Intelligent Design

• Energy system: Install solar panels on the roof for power supply, paired with energy storage batteries to meet daily electricity needs; use LED energy-saving lamps and low-power appliances.
• Eco-friendly materials: For interior decoration, choose renewable materials such as birch plywood and natural linoleum to reduce formaldehyde emissions.
• Smart control: Integrate a smart home system to control lighting, temperature, security, and other devices through a mobile app.

V. Key Points of Drawing Design

• Floor plans, elevations, and sections: Mark the positions of doors and windows, water and electricity lines, and structural reinforcement nodes to ensure construction feasibility.
• 3D renderings: Intuitively display the spatial layout and decoration style to assist clients in decision-making.
• Case reference: Taobao provides CAD construction drawings for 20/40-foot containers, including a full set of design details that can be directly used for renovation references.
