Design for Change is an approach by which structural and spatial creativity can be improved. This approach is based on three topics: First, the availability of Reasons for change like (functional or environmental requirement), secondly, identification the mechanisms of change (including the mechanisms by which change occurs) and finally, determining the Outputs of change (related to the variance in the morphology. Consequently, the Lightweight metal structures, which have the ability to instantaneous deployment, are Attractive models for applying this design approach. due to: the ability of these structures to adapt to Functional adaptation and mobile transformation, Temporary enclosure of reusable dynamic spaces, The problem of research is the need to utilizing the approach of design for change in developing transformable structures, with a focus on light metal structures that have the ability to instantaneous deployment, as distinct models in dealing with expected functional or environmental changes, the research aims to prepare a study on approach of design for change and its related issues, like designing, categorizing and constructing instantly depolyable structures ; they can be physically reconfigured to meet many changing needs. The goal of the research was accomplished according to a descriptive and analytical approach based on two topics: 1st, an Introduction About transformable architecture and depolyable structures, 2ed, essential considerations in designing and constructing depolyable structures. The research is concluded with a Conclusion and relevant main findings
