The period following disasters for families is really hard to get over, who have lost their houses. X-Box is a temporary residence for disaster survivors. Every box is for one family. Taking up little space, locked boxes are opened on the disaster stricken region, so the delivery and storage phases are much easier. Once reached at the destination, x-box is installed on the place, when it is unlocked; it extends automatically to above and to one side. Consequently enough space is generated for a family. The locks are located on the corners of the box. The unlocking movement is as the same as opening the trunk of a car. The material of new walls is textile (tent), so they can be folded and unfolded easily without taking up much space.
