The design process in social housing projects includes several inefficiencies that impact not only the design itself but the whole project results. Part of the problem is that the design includes several non-value adding activities such as waits, design modifications, and rework. Preliminary data from a case study in this research shows that deliverable control; work team coordination, communication and integration; personnel workload; and work planning and allocation are the main drivers of a good design in these projects. On the other hand, existing literature suggests the use of lean philosophy to improve the design but there is no evidence of how lean could be used in the context of social housing design. Therefore, this research assesses the most relevant drivers from the identified list for a case study and proposes and tests the use of Last Planner System and Collaborative Design to address these drivers to support social housing design. The article describes the case study context and discusses the results from the interviews and surveys used to identify the main drivers for a good design. The article also proposes a lean design process and the validation methodology which is still to be implemented.
