In this design activity, students designed a deployable (retractable) pavilion, a self-standing shell structure that is capable of altering from a very compact arrangement to an expanded configuration. To respond to changing scale, the structure obtains a transformational capacity that is provided through built-in mobility. The kinematic properties of the proposed mechanism are capable to support different stages of deployment when the structure change its position, shape and size. The suggested design consists of a system to temporarily fix the desired size or form in place. The structure covers at least 400 sqft.
