Looking for prefabricated homes in China with a distinctive exterior finish? YJD’s black grain expandable container house is a factory-built 20ft modular home with a double-wing structure. It folds for transport and opens at the site to create a wider living area.
The 20ft model can be planned as an open space or with 1-bedroom, 2-bedroom, or 3-bedroom layouts. Panel core, doors, windows, electrical setup, and interior fit-out can be selected according to project requirements.
These factory photos show the production environment and finished expandable-house units. Buyers can review the product’s appearance and manufacturing setting together before discussing the required layout, materials, and finish.
For a project quotation, share the intended use, destination, preferred room plan, and any local electrical or material requirements. The approved drawing and quotation should identify the exact production scope.
Use the expanded footprint for site planning and the folded dimensions for delivery access and transport coordination. These figures come from YJD’s 20ft standard double-wing parameter sheet.
