Model JJ-DW20 · MOQ 1 unit (sample), full container recommended · Ships from Qingdao, China

Key features

Floor area doubles on site

Side wings unfold on hinges to add roughly 140% floor area to the same transport footprint.

Interior fitted in the factory

Kitchen, bathroom, bedroom and electrics are completed and tested before the unit is packed.

One container slot per unit

Ships closed at 2.44 m wide, so freight is charged as a standard 20ft or 40ft container.

Commissioned in a day

Crane the unit, unfold the wings, connect water and power — usable the same day.

Metal carved panel facade

Embossed decorative panels on both wings — the finish buyers ask for on show units and site offices.

60 m² from one container slot

Both long walls unfold to give a three-room layout: living, kitchen and bedroom.

Overview

The double wing model is the answer when floor area matters but transport cost does not allow oversized loads. It travels at standard container width, then both long-side wings unfold on site — hydraulically or manually depending on the configuration ordered.

The unit shown here uses metal carved panels, which gives the facade a decorative finish suitable for villas, sales offices and upmarket site accommodation.
