This document is for the design, construction, and retrofitting of houses. It covers the three principal subjects related to efforts to rebuild housing after a disaster design, construction technology, and the decision whether to repair or retrofit versus demolish. The chapter provides guidance to help practitioners make decisions that result in the most appropriate solutions. All considerations and recommendations developed here are relevant for both urban and rural contexts, but they need to be adapted to the context to ensure the appropriateness of given building technology in the urban or rural environment.
