RCHI Members Laura Wainer and Billy Ndengeyingoma recently collaborated with Sally Murray of the International Growth Centre on the report "Incremental housing, and other design principles for low-cost housing" in Kigali, Rwanda. To address Kigali's critical shortage of low-income housing, they explore the promise of incremental building, where unfinished houses on serviced plots are provided for beneficiaries to improve over time. Their project builds on previous work undertaken – including a two-day stakeholder workshop – to provide a policy brief for key stakeholders in affordable housing development in Rwanda, particularly the Rwanda Housing Authority, and to build a longer-term research partnership between the IGC, the RHA, and the researchers.
