Flexibility is written into the DNA of the RDM. Because the system is based upon a series of universally sized interlocking parts, multiple configurations are possible by simply substituting parts for one another. In this way, smaller units can be made larger by simply clicking them together. Additionally, because sanitary facilities can be a major concern in many environments, Visible Good has designed shelters that incorporate Latrine and Shower facilities; all of which can be assembled by two persons in about an hour with no tools or hardware. For institutions, NGO’s and corporations involved in remote location operations or crisis response, a single building system that offers multiple configurations with ease of assembly is of real, practical value.
