Joseph Mukeku is a qualified and registered architect in Kenya who besides mainstream architectural practice is also involved in community design initiatives, and works as an affordable housing special-ist with Urban-A. He holds a PhD in architecture and urbanism and his research focused on the logic underlying the morphology of self-built environments based on a case study of the Kibera slums in Nairobi. Mukeku has worked extensively on slum upgrading projects in Nai-robi and is continuously engaging with affordable housing solutions, incremental housing and infrastructure upgrading targeting the urban poor, and focusing on participatory, com-munity-driven, scalable projects. An important component of his work is the mediation and liaison between different stakeholders, including local and central government, private sec-tor, local organizations, and the local community, in order to anchor the process and further push changes on-ground.
