Social housing (SH) upgrades involve multiple stakeholders with sometimes divergent requirements and needs. Collaboration and participative processes are essential to ensuring an appropriate value for users is delivered through social housing upgrades. Living Labs are user-centred initiatives where researchers, public and private partners, and users collaborate to develop innovative solutions in real-live environments. However, scarce research exists on how Living Labs may support the upgrading of social housing, and there is a need to explore what the challenges are that can be expected in this context. This paper discusses an integrative literature synthesis of housing upgrades developed within the context of Living Labs. Nine information-rich cases identified in the literature were chosen for in-depth examination. A living lab process was proposed based on the literature and activities and tools used in Living Labs were identified. From the challenges highlighted by existing studies, a series of recommendations to support the development of Living Labs in social housing upgrades was proposed. These should support Living Labs implementation initiatives in this specific context.
