The document discusses the design of cyclone resistant and flood adapted affordable housing in coastal regions of Bangladesh. It surveyed existing housing in regions affected by cyclones to study construction materials, designs and vulnerabilities. Based on the findings, it proposes improved housing designs that incorporate raised plinths, sturdy wall materials like bamboo and brick, and roofs able to withstand high winds like ferrocement sheeting. The goal is to develop affordable housing models that are durable and can better protect inhabitants from natural disasters.
