After investigating the architecture of informal settlements, the ETH Zurich Master of Advanced Studies Program in Urban Design at the Chair of Marc Angélil and directed by Charlotte Malterre-Barthes in collaboration with local partner CLUSTER, proposes new designs for affordable housing units in the neighborhood of Ard-el-Liwa. Selected projects show how different housing layouts and rearranging existing building components can lead to new urban forms that allow public spaces to emerge. By altering the typology of informal housing via a simple recombination of existing architectural and structural elements, the projects aim to enhance the living quality of single units and establish collective urban formations that ultimately improve entire districts.
