The apparatus and method is disclosed and seek to claim exclusivity of conception of a versatile structure that follows the maritime container ISO dimensions and that is collapsible to be stored in scanty places and / or hauled together with other collapsed units, saving transportation costs. Larger surfaces may be created by simply juxtaposing one modular unit to others, side-by-side, front-to-back or stacked. In order to allow these modules to dismount in a practical manner, the inventor conceived a “Collapsibility Mechanism”, requiring minimum labor and equipment, which is based on the two frontal frames natural swing produced from hanging them by each of the two pairs of the eccentrically oblong supports. The COLLAPSIBLE ISO CONTAINER-TYPE MODULAR SHELTER also comprises original design of profiles used in the top chassis perimeter that constitute that chassis' main structural elements, as well as prevent rain-water to flow through the unit lateral and frontal sides, as gutters do. This “Structural-Gutter” concept may fit numerous other applications in the construction industry. Governments can benefit from this invention to alleviate urgent needs to shelter people domestically and abroad. Private businesses would also find it a practical and affordable solution for many of their requests of temporary housing or mobile shelters.
