The detachable container house is a type of modular house that built with all basic parts. The flat-pack is a modular house in a semi-finished condition. The biggest difference is that the floor and roof of detachable container house are connected to the column by fastening screws, and the floor and roof of flat-pack are completed welded.
Detachable container house requires assembly of all accessories on site, and the process is complicated; the installation of flat-pack container house only needs to assemble 4 columns and wall panels with the floor and roof, the crane or other hoisting equipment would be required.
The transportation of flat-pack and detachable container house is different completely. The detachable container house is delivered in CKD condition which can increase loading capacity of the shipping container; the flat-pack house is delivered in flat pack condition.
