Container House Design

Container house design should revolve around modular characteristics, incorporating structural safety, functional adaptability, and regulatory requirements. The specific design points are as follows:

1. Structure and Material Selection

Container houses are centered around standardized steel-frame structures, with the main framework constructed from corrosion-resistant steel plates (e.g., steel with a yield strength of ≥235MPa), combined with shipbuilding anti-corrosion processes to ensure a service life of over 20 years. During design, it is crucial to evaluate the seismic resistance and deformation resistance of the steel structure: for example, a fully steel-framed structure can limit wall deformation to within 1.2mm under a 12-grade wind load, meeting stability requirements in extreme weather conditions. Additionally, wall materials should balance environmental friendliness and performance, such as using eco-friendly panels for filling, which reduce pollution and enhance thermal insulation.

2. Spatial Combination and Expansion Methods

Space optimization is achieved through horizontal and vertical expansion: horizontally, multiple containers can be spaced and arranged, connected with wooden or steel fillers to form open areas like living rooms and corridors; vertically, they can be stacked in multiple layers using bolted connections to create functional zones such as office areas and accommodation spaces. Modular assembly supports customization in standard sizes ranging from 20 to 60 feet, such as combining two containers to form a suite with an independent bedroom or constructing a two-story residence through multi-layer stacking (as seen in the classic case by American architect Peter DeMaria).

3. Functional Adaptability and Interior Design

• Flexible Partitions: A single container can be divided into two independent spaces (e.g., accommodation or storage rooms) or combined with multiple containers to form a large office area, meeting diverse usage needs.
• Pre-installed Systems: High-end designs can achieve 100% factory pre-installation, including wall finishes, plumbing and electrical systems, and furniture, allowing for immediate use after on-site hoisting and connection to utilities, significantly shortening the construction period.

4. Roof and Sealing Treatment

The roof adopts a layered sealing design: the bottom layer is laid with oriented strand board (OSB), covered with a waterproof tarp and secured with a wooden frame, and the top layer is installed with aluminum corrugated tiles or eco-friendly panels to ensure waterproofing and thermal insulation. Walls must strictly adhere to manufacturing processes, ensuring water tightness through welding or bolted connections, while using soundproof cotton and thermal insulation layers to enhance living comfort.

5. Regulatory and Case References

Design must comply with standards such as the Technical Specification for Modular Combination Container Houses to ensure structural safety, material environmental friendliness, and durability. Typical cases include:

• Self-built Project by a Couple: Utilizing scrapped containers spaced and arranged, filled with wooden planks, and topped with waterproof tiles to complete a low-cost, self-built structure;
• Commercial Design: Such as the recyclable container hotel built by CIMC for the UK or the modular application of double-story container residences.

By following these points, container houses can achieve efficient, eco-friendly, and flexible architectural practices, balancing functionality and economy.
