The Importance of Design in Affordable Housing: Lessons From Mutual Self-Help Housing in California

We focus on three nonprofit organizations developing mutual self-help housing and analyze their projects to examine how they are addressing cost increases. We find that instead of using simpler designs, they are developing more elaborate homes through intricate financing. We are critical of this evolution. First, we suggest that the original modest house design of mutual self-help housing allowed for more affordable housing through post-occupancy improvements and de facto incremental development. Second, after the modest design was replaced with a larger model, development costs increased. Despite financial innovations, including longer loan terms and secondary financing, participation by poor households dropped. Third, we urge a return to the modest housing idea. Fourth, we call for policymakers to better integrate design-based thinking in housing policy.
