What if architects and urbanists could become authors of "spatial hope"? That was the brief set by Esther Charlesworth and John Fien for their new book, Design for Fragility: 13 Stories of Humanitarian Architects.The text surveys a range of humanitarian architecture projects from a maternity waiting village in Malawi, a women's resource centre in regional Fiji, to a Cairns rehabilitation centre for people living with an acquired brain injury, and many others.
