In this chapter we have seen some innovative ideas and methods of using folding, deployable and retractable space grids. Single-layer folding grids are also being explored by Chuck Hobermann in the USA. Given the versatility of folding grid structures there is great potential for their extensive adoption for construction projects in the future. There is considerable scope for their application for a wide variety of uses such as as an economic method of erection or as a means of providing easily adaptable or demountable and reusable structures.
