If an evacuation order or advisory is issued to an area where the danger of a house collapse or life has increased due to natural disasters such as typhoons, earthquakes, volcanic eruptions, and heavy snowfall, They will evacuate to public facilities such as gymnasiums and public halls that are relatively safe and can accommodate a large number of people at once, and will have a temporary evacuation life (group life).
However, in evacuation life, people from a wide range of ages, from infants to the elderly, are laid down on the floors of gymnasiums, etc., with individuals or individual households laid down with a basket or blanket provided (distributed) by local governments, etc. Although it is small, it is possible to secure a space enough to wake up, but it cannot be separated by a partition (partition wall) for each individual or household and is always exposed to the eyes of surrounding people.
For this reason, daily activities such as changing clothes must be conscious of other people's gaze, and it is placed in a poor environment that tends to accumulate mental stress that cannot be said to ensure personal privacy. .
In addition, the life rhythms of each evacuated residents such as wake-up time and bedtime are inconsistent, and there are many cases where sufficient sleep time cannot be taken due to people's movements and voices. Physical fatigue such as lack of sleep and physical fatigue accumulate, and evacuated people may cause troubles due to minor things. Therefore, the evacuation life needs to be completed in a short period immediately after the occurrence of a natural disaster, and in the case of a long-term evacuation life, it is necessary to ensure privacy and the like.

Therefore, in an area where a natural disaster has occurred, construction of a simple assembly type temporary housing that can temporarily reside is being carried out.
Since this temporary housing is supplied to each household by a local government or the like where the natural disaster occurs, it is not exposed to the surrounding line of sight, and mental stress can be reduced. Therefore, the life rhythm before evacuation can be protected, the occurrence of trouble between evacuated residents can be suppressed, and the health of the evacuated residents can be stabilized.
As such a temporary house, for example, as disclosed in Patent Document 1 and the like, processes such as material processing and temporary assembly are completed in advance at a factory or the like, and at a temporary site, installation on a basic foundation In general, the prefabricated method is mainly used. This prefabricated construction method has the merit that the period required for construction can be shortened and many temporary houses can be constructed in a short period of time.
