Abstract: Method for the construction of a temporary shelter, comprising an even number of base modules of equal size each having an entrance at one end, the base modules being placed side by side in two rows with the base modules of one row facing in pairs those of the other row so as to form a hallway, the entrances opening into the hallway. Floor modules having the same width as the hallway are located between the pairs of facing base modules so as to join them at the bottom thereof. Two vestibule-forming modules having the same width as the floor modules are provided at the ends of the hallway so as to close it. The base modules are joined together by means of a first set of thin sheets of flexible sealing material each being removably secured between the front, the top and the rear walls of the base modules.
