The Build Change Guide to Resilient Housing (Build Change, 2021) is a freely-available handbook that provides governments, funders, and practitioners with the tools they need to carry out and support resilient housing programs at scale around the world.

The Cost of Improving Vulnerable Housing (Build Change, 2022) draws on data from 1500 retrofits to show why improving existing housing is an all-round smarter, more cost-effective investment.

Saving Embodied Carbon through Strengthening Existing Housing (Build Change, 2023) provides compelling evidence that improving existing housing significantly avoids carbon emissions in the housing construction value chain.
