Comparative housing studies traditionally focus on housing systems and social or economic policy, only rarely considering design issues. Through an examination of subsidized housing and its design in 20 countries, this paper explores how design research can benefit cross-national housing studies. Subsidized housing is essential to delivering decent and affordable homes, underpinning the right to housing. To relate design dimensions to housing systems, the analytical focus is on regulatory instruments, technical standards, and socio-spatial practices as well as housing providers, tenures, and target groups. Design research benefits the contextualization of housing systems and design outcomes in several ways. It reveals the contextual and contingent nature of regulatory cultures and instruments, socio-technical norms and standards, and socio-cultural expectations and practices that shape housing solutions. The paper concludes by considering productive ways architectural design research might contribute to an interdisciplinary housing research agenda by offering new means of theorization and analysis beyond traditional housing system typologies.
