Introduction
Expandable is based on flatpack but can be extended the building area from both sides. The main part of an expandable is a 20ft or 40ft flatpack, but with folded roof, wall and base on both sides when packed. When arrives in the site, two sides can be open and connected, so extra space on both sides will be made. A 20ft flatpack container house has only around 14sqm building area, but a 20ft expandable has around 36sqm.
But expandable cannot be stacked or even difficult to be combined, it normally used as a single house with two to four bedrooms plus bathroom and living area.
The expandable cubic is full prefabricated in workshop, all structure well connected, wall and roof panels are well installed, doors and windows are pre-set in the wall panels, plumbing and electricals are embedded and ready to use, floor and ceiling are finished, only need to fix some connections, flashings and shirting onsite.

Packing and transportation
The expandable can be folded during transportation, which makes it cost saving. We can fold the two side parts into the main center part, make it a 20ft or 40ft SOC box, put other components inside the SOC box then load into shipping container. In this way, each SOC box is one unit of expandable, so you can find all components easily onsite. Or if any delay of the project, you can also put the SOC box in warehouse or in the site, there will be no mess up or damage, no accessory will get lost either.
