Affordable housing is a global challenge in both emerging and advanced economies, where more than 1.8 billion people around the world lack decent housing (UN-Habitat, 2021). The affordable housing gap worldwide is estimated at 330 million urban households and is predicted to increase to 440 million households, or 1.6 billion people, by 2025 (King et al. 2017). Various organizations are supporting efforts to realize the Human Right to Adequate Housing, which is necessary for the three pillars of sustainability: economic viability, environmental protection, and social equity.
