Expandable Container House

Casa Box is dedicated to providing premium Expandable Container House solutions. Through our innovative folding design, we deliver the perfect balance of compact packaging to slash ocean freight costs and rapid on-site expansion to instantly multiply usable space.

Our core model lineup covers all-scenario needs: 10ft (Flexible Micro-Space), 20ft (Classic Best-Seller, High Cost-Effectiveness), 30ft (Spacious Upgraded Layout), 40ft (Luxurious Multi-Room Partition), and the F700 (Emergency Essential, Rapid Response).

Core Product Advantages

  • Sturdy Structure: Built with a high-strength galvanized steel frame, paired with fireproof rock wool or insulating EPS sandwich panels and magnesium oxide (MGO) flooring. It delivers superior wind, earthquake, and corrosion resistance to easily withstand harsh environments.

  • Rapid Deployment: Highly prefabricated with water and electrical wiring, as well as basic interior finishes, pre-installed at the factory. A small team can complete the on-site expansion in just a few hours, achieving a true "move-in ready" standard.

  • Global Mobility: Specifically optimized for international shipping logistics (maximizing 40HQ container loading efficiency). These units are 100% foldable and relocatable, making them highly adaptable for global construction camps, temporary housing, commercial projects, and post-disaster emergency relief.
