This document describes a re-deployable building system designed for Syrian refugees called Re:Build. It consists of prefabricated shelters that can be assembled with unskilled labor. The system allows for clustering of shelters rather than linear layouts and includes options for 1-2 bedroom homes, schools, and clinics. It was developed and tested in 2013-2014. The goals are to provide long-term housing solutions, create local jobs, and eventually have materials sourced within the region to reduce costs over time.
