It is estimated that around 80% of cities worldwide do not have affordable housing options for the majority of their population (1). The world needs to provide two billion homes over the next 75 years — meaning 96,000 new affordable homes need to be built every day (2).

The ‘Sustainable and Affordable Housing’ report challenges the widespread perception that affordable and sustainable housing is not a mass market solution. Many of the solutions to the global housing crisis already exist. The case study content from five regions highlights cutting-edge built environment projects, making sustainable and affordable housing a reality for all — from 3D printed homes in Kenya, community engagement and collaborative financing models in Nepal, to disaster-resilience retrofits in the Philippines.
Through this publication, WorldGBC champions a unified vision for sustainable, affordable housing and spotlights best practice worldwide to demonstrate opportunities for success that could be scaled for greater impact. An analysis of case study data derives key calls to action for policy makers, the finance community, community approaches, and the design and construction industry.
