Container Houses with Multiple Floors

Container houses can be designed up to six floors. Here are the details:

I. Number of Floors in Actual Cases

1. Four-story Building: A massive black container building stands four stories high, composed of 16 construction-specific containers. Each container is approximately 12 meters long, 2.4 meters wide, and 3 meters high, allowing for flexible stacking and assembly through standardized modular design.
2. Five-story Building: The flexible housing apartment hotel in London, UK, adopts a five-story modular volume, with each room constructed from 30-foot recycled containers. Its facade is dynamically formed by welded steel fin elements, providing both privacy protection and shading.
3. Six-story Building: The container residential building in Johannesburg, South Africa, reaches six stories and is stacked from 140 recycled containers. The building is divided into blue and green sections that tilt outward, forming a triangular courtyard, with open corridors on each floor serving as public balconies. The Highpoint Treehouse project in Texas, USA, also features a six-story design, with each floor equipped with an independent balcony and bedroom.

II. Feasibility of Structural Design Supporting Multiple Floors

1. Modular Connection Technology: Modern container customization achieves stable stacking through multi-story frame connection technology. For example, the three-story office building of COSCO Shipping Heavy Industry (Nantong) combines 48 six-meter standard containers with 48 fourteen-meter extended containers, ensuring uniform structural stress through high-precision factory prefabrication.
2. Lightweight Skeleton Design: In the three-story office building project of Qidong Container Factory, 6mm steel plates are bent to form top beams, bottom beams, and side beams, replacing traditional heavy square tubes. This design ensures structural stability while making the individual container skeletons more lightweight, enhancing overall construction convenience.
3. Waterproof Node Treatment: Multi-story buildings require special attention to inter-floor waterproof nodes. For example, the UK apartment hotel ensures space privacy through mesh patterns printed beneath the glass while using high-performance double-layer laminated glass units to meet waterproofing requirements.
