Abstract: The present invention is a reversible modular coordination system comprising central structures that are multiple connectable and disconnectable, flexible and independent of each other; versatile floor plates that are loose and positioned on the lower beams of the central structure; versatile ceiling plates that have flags positioned in the upper beams of the central structure; independent intermediate flexible side plates that are positioned in adjacent edge lines or vertical frames of the central structure; and groups of multipliable connective and disconnective nodes; forming individual modules that can be used in the building construction; and the use of reversible modular coordination system for the construction of provisional buildings as well as for the construction of perennial resilient and not resilient buildings.
